Hello,
Hope you can help, My son has a l120 about 7 years old, came to me to fix it and I am out of suggestions. Engine was smoking and losing power. Some one told him the carburator was bad for allowing gas to enter the oil. I drained the oil put mechanic in a bottle in the carb and let it sit for 2 days and took the bowl off the carb and cleaned it real good, put new gas , filter, gas line oil spark plug on it.
Took it back to him running great. He even mowed with it for abut 5 minutes, put it up 3 days later got it out smoked like a freight train and lost power.
Can anyone help with this proble?
Thanks much,
Daviedav

My ESP is in the shop for a tune-up. You don't give us much to go on to help you. We don't know type of engine, model numbers, L-head or OHV, type of unit it is on. If I had to guess I would say you have a blown head gasket, if it is a OHV engine. Or it could be the mechanic in the bottle.

(Mechanic in a bottle) Hmmm I can't see anywhere that it tells you it repair's a f*&^k up carb seat...! but goodluck anyway.

Has the oil level risen since he last used it? It sounds like whoever told you the carb was bad for allowing fuel to seep past the float needle was correct. Check your oil level and see if indeed fuel has entered the crankcase. You can affirm this by checking for an unusually high oil level. If that's the case, you have to clean/replace the needle & seat. (Possibly even an overlooked leak in the float itself) What engine model is this again?
