Thanks :) Was able to short test it outside, after a few pull on the rope (carb diaphragm has to fill bowl in the tank to allow fuel to the main jet) it started and ran pretty good :) I just tested a few minutes without air filter/box, let it warm 5 minutes and looks it can idle and rev. I have...

Hi, Remove the carb from the engine, remove the fuel by orienting them in any direction so you have not to open it. Then try to blow through input line / port when normal orientation you should be able to, flip it upside down and it should block the ability to blow in. If not blocking, as said...

Hi, lot of time has past since :) Busy busy summer, and I tried to order parts from firedog.com, without success. They won't ship worldwide during the COVID pandemic, ant I can't contact them because their formulary system always fail me at the captcha test like I am not human... so I can't...

Help to find your model number : https://www.briggsandstratton.com/na/en_us/support/videos/browse/how-to-find-your-push-mower-engine-model-number.html Are you sure the crank is not bent with a broken sump ? When you got the numbers you can have the owner manual and the Illustrated Part List to...

Hello ! For sure someone can help you there :) Can you post the complete motor code please ? Its stamped somewhere (above the head, or above muffler, if a heat shield), like 123456-7890-XX Pics of carb, governor arm can help too !

Hello, A little follow up. Not a lot of hours on the engine, but works fine, gasket is fine, no leaks. Frame was painted (not by me, credits to the current owner :) ) and I had to change the flimsy fuel line I put... now I bought the right braided line SAE standard fuel compatible ! I add...

Great, it's quite experimental making about the same bowl system from pictures ;) They are usually rated at 3600RPM for max power, with a lot of variations depending on application, air cleaner. Peak torque is at 3000RPM, Idle is at 1750.

I took a pic for you, the little tang is plain, so nothing goes out there. As soon as you bowl is not emptying, it should be ok, and this should not happens in 10 sec

Thanks for proposal, I would be happy to have you doing the seats for me, but as you said, sending the block to you is 60$ US ! And I think about the same for the return... so we reached the value (or more) of the running engine :p And here, nobody do that on old flatheads, and on OHV you just...

Ok if the timing is right and the spark is good, I don't understand why it does not fire if you put some fuel in the intake. 80 PSI is low I think for a not that old OHV engine, but someone more knowledgeable than me should help you for this case !

Oki... But I don't have seat cutters and I dont plan to buy some, I checked and they are way too expensive, like 300-400$ ! If I only buy a new valve this make a difference without touching the seat ? Yes valve guides are within specs, intake is perfect and exhaust as a bit of play - but the...

So finally, I clean the valve good and I lap them. The exhaust had a little bit of pitting, but should not be a big concern. The intake worries me a bit more, the ring is clearly at the outside. An the seat "seating" size is at max of tolerance according Briggs manual. Anyway, I give it a try...

If you have spark, gas mixture and compression it would run. Except if you hit something and it stopped ? If not, did you try to dump some fuel in the intake to see if it run a few seconds ?

I cleaned the valves and inspected them more thoroughly. I am a bit concerned with them, some pics below : - The intake has quite a deep groove, is this a problem ? - The exhaust has some "pitting" on it, should I clean it with something more abrasive, like a scotch bite pad ? - I'm still...

I progressed in the disassembly this weekend First I made a little "tool" from a flat steel bar, two holes and a bit of grinding to allow me remove the starter clutch. I know a tool exist, but time to order with current restrictions and shipping that will double or triple tool cost, I went DIY...

For this price it is a good choice I think. Don't forget to charge the battery in the winter season and the regulator will pay itself on the first battery, it will last twice as long if not fried by charger and not depleted during winter.

Hello ! Time to remove the carb, check if float move freely and flot needle does not stuck. While in, you could clean the jets and passages, especially if you have some dirt in the bowl. Check if you have good flow from the line while it's disconnected to service the carb, perhaps the problem...

Nice, well done ! Thanks for the update ;)

Hello, You never had an hard stop of the engine ? Could be the flywheel key sheared, this cause timing issue. For the valves, they are known to to lose lash and burn if you don't set it again correctly. You should lap them to see if they seal all around. If you have questions about precise...

Thanks for your comments tom3 and Its Me. So I'm not alone to love them ;) Yes I need a head gasket for sure, don't know if I will buy the whole gasket set, the motor was pretty greasy - so some leaks exist here and there. For sure the dipstick tube oring is toast, but other probably too...

You can use an higher amp regulator as it normally has to clamp the voltage to 14.4V as cars do. I don't know exactly the construction of the briggs 5-9amp but as said above this should be fine for a basic application. Mower batteries does not last long because they are cheap of course, but you...

I continued my work on this 5HP (and my monologue here :p ) This was a bit less fun, has after removing tank and carb, this was only cleaning. Greasy stuff with dirt all around the block, but I need something clean to be able to open the crankcase. Checked the valves lash, no surprise with...

You are welcome. Perfect if you lap the valves. Some bolts/screws have pretty coarse thread, if they cut good this can work. https://www.amazon.co.uk/Bolt-Base-Stainless-Steel-Screws/dp/B00LCH1DUG If you measure et cut it to good length (no need of a sharp tip) you can't go in the guide, the...

Hello, yes quite tiny pics. I think you can go the size (pixel hight by piwxel width) as long as your don't exceed 1MB of size. But as your reduce the dimensions file size reduce too; reducing the size to something like 1600 x something and using jpg with 90-95 of quality result in good quality...

Hello, I saw your post yesterday but I was surprised by this design too, so I thought someone more knowledgeable has the answer. It seems a bit odd for many of us so I did some research... On the part list (I am sure you already have it) it looks like this goes under the valve... thats right...

(I was limited to 10 pics...) The 3 longs bolts are not in the right spot anymore, and we have marks on almost all fasteners. Someone did some repairs -or try to do- on it. Inside there is some carbon build up, I'm not sure the valve are sealing good. Cylinder looks ok, nothing I can feel with...

Hello all :) Last year I worked on a similar engine used as a generator. I love those old Briggs flatheads, especially the 5HP I/C with sleeved cylinder, dual bearings and oil alert. Si I won for five bucks the auction of the following motor, that was the description, I even don't know what was...

Hi all, My father mower started to develop an oil leak on the rocker cover. This is an OHV 6hp briggs vertical for a Toro walk behind mower. This design is with a die cast rocker cover, then an gasket, than a rocker plate (where the studs holding the rockers are), a gasket (cylinder head style...

Back to this Mitsubishi clone engine after a while ! It's because I was waiting on the gasket cutting (and I was working on the Briggs 5HP anyway). For the crankcase gasket I know I can cut it by hand or any small hammer (even if it's aluminum block should work), but it's not fun or at least...

Received my small range (5-25Nm) 1/4" torque wrench, so now I am able to properly torque bolt like head and muffler :thumbsup: Already have a 1/2" bigger (28-210Nm) one since a while, but it's more usefull for car than small engines.

Ha yes, I was wondering why clearance always getting closer over time. Yes bad seating valves, if you don't solve it quickly this can make a lot of damage I believe you. Finished motor assembly - started with remounting the head, with proper torquing sequence (all is in L-Head Briggs manual)...

Yes, I think it's quite a good way to do it, but I don't have valve and seat cutters (and don't plan to buy some for just engine - I'm not in the business, just an hobby). So I filed down the valve stem until having the good clearance, reassembled the valve springs and retainers, put back...

I continue my monologue :laughing: Was able to borrow a valve lapping set, with fine paste and asmall suction cup that just fit on my small briggs valves ! So do a quick lapping, ring is not a the same place on exhaust and intake... more inside on exhaust valve and more outside on intake...

Tried to remove the big dent on the shroud, but as you can see I'm not a body worker :laughing: At lest it's better, even if it is far from perfect Removed this ugly orange Bosch sticker in the same time. A plus

Hi there, Received my tool to play with ! Its a bit less easy to use than what I think. The spring on exhaust side is strong, but once the tool is installed it easy to remove the in of the valve. On the intake side spring is more soft, I was able to quickly remove the retainer without it... but...

Thank's Scott ! Yes for the moment it's going well ! Yes for sure you can't know all governor styles, including this old particular one... What I just try to do is thinking and try to understand what was wrong or not set right; so when I fire it up I can quickly find the right setting. But...

Thanks guy for help, pictures ;) About power distribution, frequency and voltages.... if someone want to discuss that (technically - not politically) please open a thread. It can be very interesting. But for now, we just have to use the power we have where we live :rolleyes: this mean I have to...

Thanks Scott for information. :smile: I have a small RPM counter / hour meter, the simple one you wind 5 turn on the spark plug cable. It's not the more practice but works great on all my single cylinder engine (checked factory settings on my new ones, adjusted the idle of my old briggs...

Thank you all for all advices, link and explanations ! :thumbsup: really cool. I think I will discuss thinks by topics, as many replied for same subject... First, about 50Hz and power. Yes most of people here have habit for 120V / 60Hz, while a big part of the world is 240V 50Hz. I don't care...

Hello :biggrin: I just bought for cheap this old Briggs and Stratton 5HP flathead generator ! Gen head is a bosch unit, 2150W Engine feature cast iron bore, double crankshaft bearings, oil guard. Its a 132237 0363-01 engine, year 87. Was able to find both owner manual and part list on B&S web...

I continue my monologue :laughing: Was able to "crimp" the carburetor plate on his shaft again (was loose before), so no play anymore. I should receive gasket paper soon, meanwhile I cleaned both surface so I'm ready when I have cut the new gasket :

Hello everybody, I'm a fan of engines and love to play with small engines (as I don't have space place and money to play with bigger :laughing:) I have fearly new power equipment so apart oil changes nothing else to do (yet)... This is where come this old 71 2.25HO horizontal Briggs and...

I continue the story :smile: I spend a few minutes on this old generator when I have time. Submitted a form to have the gasket "on request" but the answer is "5 or 6 month" :laughing: So I ordered gasket paper and will try my best to make a decent one ! I start to clean the old gasket and...

Thanks all for help and advices so quickly ! The good new is I was able to open the crankcase cover ! :smile: The "not so good" new is that was with unconventional method... as you can see below I had to use the 2mm play I had on the shaft to put some wood spacers between cover and case...

Hello everyone, First I'm new here, I try to read basics thing but if I do something wrong let me know. I used forum a lot when I was younger, but not so many since... If this place is strictly reserved to mower let me know I remove my thread... I like working on small engines, manly doing...
