hello I have a FL40 Allis fork lift with a Buda G-153 engine and it has a carb it started smoking real bad it would fill a 2500 sq ft building in seconds so you could'nt see 20 ft away the engine runs ok no engine miss dead cylinder It had a coolant smell to me so I pulled the head expecting to see a blown head gasket it wasnt blown sent the head to machine shop had it pressure checked it is ok. What can be the problem? Only other thing to note is it is a bit overfull on oil not with antifreeze but gas smell this thing is not used very often and short running times that is what I contribute the over fill and smell in oil

Do you have an external fuel pump on the side of the engine? Sounds like the diaphragm went out and thinned the oil down until it started passing oil past the rings.

Yea, I can fix that.....
