| I have a craftsman with a 15.5 hp turbo cooled motor and one day i decided to pulley swap it and bypass the governor so i could get a little extra speed by pulling on a string (i only did this once) i rode it all over and then it shut off and would not start again. I cleaned the piston and cylinder walls thourougly and it has good spark. I think i may need to add oil and clean the carb. I tried to start it this morning and it fired once then died and wouldnt start again. | |

| I think it sounds like a carb problem, but then again there could be a whole slue of problems..Not to get you worried, but I would just start with a good carb cleaning.. try this, take a little gas in something you can pour small amounts from and drip some gas directly into your carb without the air filter..as you do this, turn it over..If it tries to run, but struggles when you stop dripping the fuel, then It might mean you have a carb problem. If it does nothing, you may have a carb problem where it is giving too much gas..hence flooding the intake....try that and see what happens
running without a gov without changing some of the stock inturnal parts can be risky. I personally can not attest to the uncertainty, but I have seen alot of people mentioning that unless you are rebuilding with performance in mind, leave the gov on..

| This may help
Instead of using gas to prime the engine, I use spray bomb carb cleaner. They usually come with a straw that lets you aim it right down the bore.
Its my best method for testing engines on site. If it will run on carb cleaner it will run with a carb job. | |

I suppose If you have the stuff go for it..Do you have an air compressor? helps down later in cleaning...Please wear eye pro! I know you arent using carb cleaner spray, but I have had it in my eyes three times...sux | |

| Dou you have a compression tester?
Does it feel normal when you pull on it.
Time to go down the list,
Does it have compression Does it have spark Does it have fuel Is the timing right Is the mixture right
If these things are correct, a good mototr should run
If not look for mechanical issues | |

| These are a couple pics of a cast flywheel on a pulling tractor that exploded: Yeah its a modifed motor, but its pretty much what could happen if a cast flywheel weakens - two things could prevent this - proper speed parts with a billet flywheel or a bigger motor . My murray had a stock governed 18HP twin that ran around 30mph - the original 14.5HP OHV motor didnt have enough power for me. | |

| It was running on sarter fluid so i cleaned up the carb a little and blew out the jets and it fired right up but i forgot to hook up the throttle and governer so it started to rev up so i shut it off and hooked it back up but it wouldnt start because my battery is dead. | |

| Ive got the battery charging but the compression is allot higher than it was before i think i put the rod for the intake valve on the exhaust valve and vice versa. ive got a fuel leak somewhere i think im gonna drop it off at western auto and get it fixed by the pros | |

You can be serious.... Did it get liquid locked? what happens is oil floods the cylinder and its virtually impossible to start.. you have to remove the spark plug and give the flywheel a turn with your hand...Slowly, watch for oil to come out..you can also, push a length of paper towel in there and see if its full of oil. you got to flush it out and even then itll burn and smoke for a bit.. Watch this video of 1PUGLIFE its an oldie but goodie a romp with pug pt 2 of 3 | |
