Success at last. Cured carb flooding. Now before I explain what I did, I realize that the needle seat was the only component that I did not change to fix the flooding because (a), I would need to order one which would take a few weeks to receive and (b), there is a very slight possibility that...

I gave the shaft a good clean with very fine paper and applied plenty of grease when re-installing the pulleys. Hope you can see what I had to make up to get the pulley removed. I would guess that a few tons of pressure was applied in order to get it to let go. Copy and paste this link to see my...

Would have tried that earlier. I polished the seat where the needle rests and inspected it under the microscope and all looks good, however one thing on the carb is not original and that it the O ring on the bowl. I was thinking that if the non original O ring was a thicker gauge ( which I am...

Thanks guys, I am pretty sure that I cleaned all jets etc recently, however I will remove the carb later today and use my inspection scope to take a close up inspection. If all looks ok I will put a shut off tap on it as suggested by Fish. I was thinking about doing this but wondering how do I...

UPDATE, Fitted new float and float needle but still flooding when not running. Everything looks clean inside carb.

I own the machine from new. Took it out of the box myself about 1996. I guess yardman fitted the engine to their mower and fitted the manual choke and put the small screw in place to stop the auto choke facility that came already fitted to the engine. Easier to put the stopper screw in place...

One thing that puzzles me on my engine is the choke setup. My mower has a manual choke but also has a choke link on the governor bracket . My understanding is that at full throttle this choke link applies the choke slightly for some reason. However there is a screw inserted in one of the holes...

Best of luck with the Jap engine.

Thanks, I don't have any experience lawnmower engines etc as this was my first attempt at lawnmower engine restoration since I rebuilt an old BSA motorcycle engine about 30 years ago. I borrowed a honing tool and took the glaze of the bore also. I was just wondering about the increase in...

Final observation, Checked the compression cold today to compare readings since I replaced piston and rings etc and measured 70psi now. Wondering if this is ok.

UPDATE. Received the piston / rings today and fitted them. Fitted new head gasket, torqued head, seated valves and checked clearance, made crankcase gasket as I didn't order one originally but I made with gasket paper which is the same thickness as the heavy one that is supplied in the kit for...

This is how we did it in the old days. https://www.dropbox.com/s/u8hjcl3v1zeojbc/2007-10-19%2014.43.44.jpg?dl=0

I have a rocket M5 plugged into a 120 degree panel. Customers local to me ( up to 1 mile ) use nano stations and ones further away use power beams. My rocket went faulty recently after 6 years. https://www.dropbox.com/s/oj686zn4ysk4hri/20200401_133208.jpg?dl=0

Use Ubiquiti gear . I have 12 friends working of mine at a distances up to 7 miles.

Thanks bertsmobile1, I didn't know that the side valve engines were referred to as L head. I think I have all the information I need now that B&S sent me the valve clearance measurements. I am going to check the valve clearance and re seat them while I await the new piston and rings to arrive. I...

Thanks StarTech I will take a look now. I think the manual in post # 16 is for a different type engine. I stand corrected ??????. UPDATE. I sent an email to Briggs and Stratton via their website and to my surprise I got a response in about 2 hours with the valve clearance measurements for my...

Hi, That makes sense. Never thought about how to adjust the valve clearance in my engine setup. My full engine details are28D707 type 0123-01 code 951215ZB ( or Z8 ). Did you post the link to the manual. Thanks again.

BTW, As I await the parts delivery I am wondering if it is a good idea to check the valves and maybe re-seat them. Any idea about the valve clearance settings on this machine as it is fixed.

My engine is old type splash feed. No oil pump.

I see 3 listed of different thicknesses . Whats the procedure in selecting and fitting. I take it that its got to do with crank end play ?????. The one that is .015 is listed as standard. My engine is year 95 ( code 951215ZB ). Maybe I can make one with .015 paper.

Thanks for that. I will see if I can get one. If I realized this earlier I would have ordered one when I placed order for the piston.

Thanks B, I ordered a piston and rings and a cylinder head gasket this afternoon. I reckon that as I have the engine removed and stripped, the extra cost for a piston is well worth it. I intend using a chemical gasket on the sump casing. I cleaned the crank shaft that held the pulley with some...

UPDATE., I had to make an attachment to fit tight to the crankshaft and put pressure against the pulley shoulder using an hydraulic pullers. Severe pressure was required to remove the pulley. I now have the piston and rings removed and I am going to order a new set of rings, wheather the...

I setup a flat piece of cast iron ( not ideal material ) with a slot cut out of it that fitted snugly around the main shaft . I welded two vertical pillars on the flat cast iron that I placed into the cross arm of a hydraulic pullers. Putting pressure on the pullers lifted the iron plate up...

Hi All, I have removed the engine from my MTD Yardman mower to check the piston rings as I noticed a large "blow back" pressure ( my own term ) when I remove the oil dipstick when in use last summer. I also checked the compression when cold and remember it reading 55psi and 90 ish when warm. I...

Hi All, Just came across this site . Hopefully some forum members may have a machine similar to mine which is rare on this side of the Atlantic. My machine is an MTD Yardman, 136C561C643 and is mid 1990's. Never had any issues with it over the years until now. While replacing all the drive...
