Hi slomo. I believe it has just one main jet. See pics. Plugs are Champion RS14YC

I hear ya, slomo, and have considered the countless variables. Though an 80-100F variation seemed a bit excessive to me on a 782cc engine. The fact that you are saying this is normal, I will sleep much better LOL! Thanks again! - Ken

Good point. I will check that the valves are seating properly

Hi slomo. I am using an Infrared Thermometer. Even if it is not reading the exact temp, the differential is still accurate of course

Hello All 1988 Onan P220G Opposed Twin. S/N unknown. MFR date is stamped on the flyball cover. Electronic ignition. Awesome beast of an engine I got this engine as a POS on Craigslist and rebuilt it from ground-up End result of my build is that CYL 2 runs much hotter than CYL 1 by...

Turned out to be a fuel delivery problem. I rebuilt the Carb and flushed the fuel system and she works. Thanks all! - Ken

Surely starving for fuel. kjonxx, I had checked the fuel cap by loosening and that isn't it. The same BS continues But I've been somewhat lazy in the last week - Argg! I still must check the fuel output from the pump to ensure consistency. As ILEngine states, there is blockage somewhere...

Thanks ILEngine. What timing for this to happen just when the PTO does not engage properly. Oh well "Fuel flow restriction some place" for sure, and I will find it. Will check the output flow from the pump to the carb first to ensure consistency

Hi ILEngine I always appreciate your feedback - Thanks. What is that, the impulse line which drives the diaphragm inside the pump? It's on my left as sitting on this now-POS. I checked it and it has not been messed with and appears to be in very good shape - Still pliable and not rotted or...

Hey All New problem apparently, and possibly related to the original issue of engine dying after PTO is engaged Starting engine on Choke, reduce to highest RPM w/o choke, PTO not engaged, not moving in forward or reverse - Just sitting on it in neutral. Engine runs for a few seconds then...

Hi Bert Parking Brake ON. Stood up and engine continues to run fine so all good there With deck repaired (new shoulder spacer on the Idler Pulley) and fully installed, engage PTO, engine now sputters till it dies. Used to be it would cut power immediately or so it seemed. I played with the PTO...

Hey berts. Thanks. I will check this seat switch and parking brake ordeal tomorrow ILENGINE, I have yet to check out the reverse safety ASSY but will do. I value your theory and thought process Mr Seat Switch is a 4-pin configuration which is new to me. Lots of safety switches on these...

Hey Hammer I hear ya. There is something wrong with the deck which I noticed only today during further inspection. 3/4's of the spacer washer that secures the idler pulley is broken off at the head and causes the ASSY to ride high and probably unstable - Mr Idler wobbles like a(n) SOB. I will...

Hi MM Good idea. Will check these points tomorrow Ken

Hi Hammer Deck installed, started engine, engaged PTO, engine dies PTO engages fine with belt removed Strange though, with PTO engaged and spinning and no belt, I am able to travel in reverse w/o using the override The spindles spin freely I confirmed the belt configuration / routing to be...

Hiya GearHead. Yes I have. All three rotate without interruption and the belt is in great condition. The mower has only ~50 hours which is pretty low all together and this is a 2015 model. The thing is in like new condition

Thanks evh. I have checked and both are firing. My next step is to inspect this mow in reverse linkage behind the left rear wheel

Hi Bertrrr, it's an electric PTO. Will check that out

Hello All Model: XT1 M/N: 13WQA1CQ009 DOM: 03/2015 S/N: 1C125H20445 Engine: Kohler 7000 Series 24hp Cub XT1 50" Shuts Down when PTO is Engaged. It doesn't sputter or anything; the engine just shuts off quick With Deck removed (no load), the PTO engages just fine. This tractor has just 50...

Scrub, yes. Solid meaning they have pull, and there are three magnets as I realized yesterday upon tear-down of the machine

Hello All Stihl This BR-400 is all OEM except for an aftermarket Carb FYI. The unit is probably 15-20 years old and is in great overall condition ISSUE# 1 It appears to be running lean based on the white-ish flavor on the plug after a full-throttle run through the yard. Also, after 15...

Regurgitating this thread. New coil (3rd one including the ORIG OEM), still no spark. Really weird. In the case that it is/was the plug, I did try a CJ8 in-place with each coil. Nothing, nada - Whit's end. Please share anything else I should be checking. I disconnected the kill wire by the...

Hey Del I am going through the very same problem by the way. I think that is why I am truly interested in yours 2-cycle Echo PB-403T backpack blower OEM coil - no spark Aftermark coil - no spark Is this even possible. I've ordered another coil from a different MFR. We will see

Yea, sorry. I think I misunderstood the full context of your initial posting. So see pic. You're doing this, right? Just making sure b/c I don't want to misunderstand yet again LOL

Hi Del. You should be touching the spark plug's electrode to the engine block or something grounded to see spark. That's the way to check spark. I think you do you fire

Hi 7394. Yes, base touching the head. The pic is just to show the machine. Got to be bad coils

Strange. I took care of both these possible issues. Gapped with card and disconnected the kill wire. I am thinking bad second (aftermarket) coil. I am going to exchange it for a replacement. Thank you Joed, Scrubcadet (a Taryl reference - Nice touch) and AMZ

Hello All Echo PB-403T Back Pack Blower no spark issue Now has a new (aftermarket) coil, I've changed the plug and the flywheel magnets appear solid. Still no fire. Two bad coils, ORIG OEM and aftermarket product? I welcome any good words Ken

Hi All Apparently I 'allowed' a connector from the Stator touch ground on an Onan P220 during a bench start. It fried the rubber/plastic off the connector that puts out AC. So, new Stator, or is it possible that I instead or also destroyed the Voltage Regulator? Maybe the coil is done? I...

Hey Semi Re: but then stops Does it start and run for just a bit or doesn't actually start at all? The T110 is a very newer mower I believe. $2000 at Lowe's? (a quick google). Adjusted the valves: You've gone far so far

Hi PTmowerMech That video was awesome. And who doesn't love Taryl?!?! Tell me one But in referencing the video, I believe this has *always* been a part of the game, and of which we are and were all a part, even in some small way each of us. Awesome post PT guy

Hey Lindy46 of 78 and still groovin'. Your snake oil might be a Zinc Oil Additive at first thought. But you might also be running a little rich on the fuel or the valves are shot or your rings have seen their day from lack of oil changes and/or extreme use Change the air filter first or...

Does the engine die *immediately* up engaging the PTO, as though you turned the engine off, or does it huff and puff and die eventually post-PTO? If it is a quick die, I'd say you have a bad safety kill switch gone wrong somewhere

Check the Spark Arrestor in the muffler. If it is caked, remove it and throw it away

Echo - Nice. Does it REV UP fine with no bogging down and hold a strong top-end RPM?

Maybe starving of fuel. First thoughts: You might have an air leak going on somewhere, or an obstruction in the governor linkage. Fuel filter clogged? Do share the make and model# of your engine when able

That is a giant swath of truly uncut grass, in a straight line no less. Maybe check to see if one of your blades (center) is mounted upside down by remote chance. I have an old non-tech Jacbsen 46" and I don't have this problem when I mow any grass

Great, thanks. New Valve Springs then too while I'm at it. Weak springs will result in valves not closing completely I believe

Thanks ILEngine. Will new valves cure the problem?

Hi Rickcin I would remove the ball valve and take it to the local hardware store (if there are any left nearby) and match things up Ken

Hello All Briggs 4hp horizontal not running just right. 1976 model 100292 on a Troy-Built tiller. VID: Flywheel key is intact Good compression Carb is rebuilt 100%. I actually tried 3 different carbs and got the very same result Bowl in tank has plenty of fuel No leaking fuel Has good spark...

Thank you very much, StarTech!

Hello All Stihl BR400 Backpack Blower Replacing the coil. The original has a wire coming out of the housing which the new aftermarket ones don't have. I am talking about the wire with the eye loop at end. Do I need to care that the new ones don't have this wire?

Howdy Gunship. I am guessing the engine maker is Briggs. Please confirm. If so, please share the info below when able 1) Model# 2) Type# 3) Code# This info should be on the blower shroud or somewhere somewhat obvious Ken

Hi Lawn Addict. Still more/less 14.75". I source impossible product for a living actually (semiconductors, etc). This one is impossible so far. I am hoping to get an impossible find using this portal is all. I've been looking for quite some time

Hello All I am looking for 2 blades (out of three for the deck) for my: Jacobsen Product Number: 53201 AKA Jacobsen 1000 53201, or just "1000" sometimes Serial: 13722 Production Year: 1979 So just by remote chance, if anyone has 2, I'd consider a buy

Hi back I took dial bore gauge readings during the rebuilding. Both sides are true and perfectly round left to right and lower to upper - Amazing So thanks again for the help here. I do have a STD honing tool - A spring-loaded three-stone. Will use that instead of my 3.25" ball hone Ken

Hi IEngine Ring Gap on on this Onan should be 0.003-0.008in. The source of my info is here: www.wersis.net/onan/p220g.html The actual ring gap is 0.015 which is way out of spec. I will purchase a new full set of rings at OnanParts.com and do a ball honing to see if I can level that out enough...

Hello all, I don't have the further specs on this engine as the information was not visible when I got it. Best I can guess is that it's an early model P220 (with electronic ignition) based on what OnanParts.com mentions repeatedly when I had bought parts. Their site is very helpful in this...
