Yard Machine 5.5 hp tiller it won't stay running unless I manually hold the governor part in the right spot until it stays running but the second and let go it dies or I prime it to keep going

Carburetor is not supplying fuel to the engine correctly. There probably is a foreign object partially plugging the metering jet inside the carburetor.

Engine starts but won't continue to run. Choke doesn't stay closed after starting. will stay running only if I hold choke closed manually.

let it warm up with choke closed manually after it starts to stall with choke closed open it and dont let it stall u can learn to play with the choke a little to get it to run right GOOD LUCK!

Yard Machines rototiller front tine- having problems starting

Sounds like you are either losing your "prime" or your carb needs either, cleaning, rebuilding with a kit. Probably a cleaning will do it. Watch U Tube there are wonderful people who film the whole process from tear down, to replacement. Com'on! Get into it its easy and it don't take long. Then you'll always know how to do it!

Mtd yard machine snowthrower not starting, doesn't sound even like it is firing, new gas, new plug, oil is full, emptied gas tank and ran dry before storing last year, blizzard tonight, help!

First spray a prime down the throat of the carb with the choke in the run position and attempt to start. If the motor hits and runs for a second then its a fuel related issue and you will need to remove and clean the carb. If it wont run or try to run on a prime then it may be an ignition issue. check for spark. If no spark then remove the ground wire from the module and check for spark again. If still no spark suspect the module, if spark with ground wire removed then wiring or switch is the culprit.

And make sure you dont over look little things like... does it have a fuel shut off valve and is it open? Is there a safety key and is it in -place? etc.

Tiller won't stay running

If you choke or prime the engine, it starts up for a second or two and dies, the carburetor need to be cleaned/repaired.
