Sears 4000W 8HP doesn't idle up under load

I bought this unit about 1992 from Sears and worked fine until recently. Now it will idle but only puts out proper voltage under load when it is manually adjusted for engine speed. The linkage to the carb is ok and throtle on carb works fine.

I posted an answer to a similar question here. You probably have a broken current transformer or a bad idle control board.

Rate me?

If you feel that before getting the fuel car was fine, and something has suddenly happened after re- fueling the car, it may be due to the contaminated fuel or the clogged fuel filter.

The motors in a garage door opener are under quite a strain and will not run too much without overheating. The thermal overload will cut them off until they cool. This could be your problem. The model number of the opener is on the end of the motor unit nearest the door and you need that to make sure you have the right keypad. There are more than one and some will not work.

Sounds like a small leak at head gasket or Water pump going. Small leak on head gasket under idle will leak slow, But when under load will leak faster. Have a compresion check done on the cylinder to locate. Also you might want to try a presure test on the coolant system. Good luck and hope this helps to get you going again.
