Lawnmower will not run on its own. Unless helped with starting fluid.
Hi I have a craftsman 4.0 HP 917-388260 that wont run on its own. Ive completely disassembled the carburetor and soaked it overnight in solvent then sprayed it aggressively with carburetor cleaner. All parts are clean and all holes appear to be clear including the jet. But it still wont run! Ive got fresh fuel and it is getting to the carb because I pull the bowl off and there gas in it. Any help would be highly appreciated!! Thanks!

The couple of "starts only if snort of ether" lawn
mowers I've serviced, the problem has been leaky or missing gasket between the carb and the side of the engine body. Please install said gasket if missing. If gasket is there, don your surgical scrubs and disposable gloves and seal the gasket on both sides with Permatex IIb non hardening gasket sealer. The stuff takes days to wear off your hands. (Alcohol drygas removes the stuff.) .. Christopher A. Young Learn about Jesus www.lds.org .. On 8/12/2013 1:24 PM, wrote: Hi I have a craftsman 4.0 HP 917-388260 that wont run on its own.

Sucking air downstream from the carb, choke is

I may have sent the wrong information. Looking
again. After the squirt of ether, does it start and run, does it start and die? Apologies if I read your post correctly. .. Christopher A. Young Learn about Jesus www.lds.org ..

But then again, a squirt of cas into the carb usually does the job equally well. Unless the engine is partly flooded or the spark is weak - in which case ether lights a LOT easier than gasoline. That said, My first teaching experience came because the regular teacher stupidly poured gas down the carb of a 6 cyl chevy while cranking it, trying to get it to start. It backfired and lit the gas in the small container he was pouring from, and he pulled back, splashing the now burning gas all over his arm and chest --------. If he had been using ether it would have been a flash, and that would have been it. He may have lost some hair and got a "sun-burn". This way he was off work for 7 months. |

My little ETQ generator, won't start on the
recently purchased gasohol. Not after choke on, choke off, and more than a dozen pulls. Will start on ether. I'm going to pour the recent gas oil mix in the truck, and buy some new ethanol free gasoline, and see if that works better. My ethanol free lawn mower starts on the second pull. Why not my generator? That said, a squirt of bad gas won't help start an engine, if it won't start on bad gas. .. Christopher A. Young Learn about Jesus www.lds.org ..

Well, if bad gas is the reason the lawn mower won't
start, adding a squirt of "the gas which is available" won't help. Make any more sense, now? .. Christopher A. Young Learn about Jesus www.lds.org ..

I's also wonder if he blew the carb out with compressed air? Removed any welch plugs that need to be removed to get to ALL the orifices? I doubt just soaking it in carb cleaner is enough if it's been gummed up. |

Thanks! check the flywheel brake, my weedeater lawnmower would disengage the brake properly, if you poured gas into the carb, it'd run fine, but if it turned off, you had to move the brake over and repeat the process. I replaced the braking mechanism, now it runs like a charm |
