Hey,
Im trying to break my engine in. I've got it started up, but when its running there is fuel bubbling up through the head. I think it's coming up in between the crank case and the head.
Also, the when the engine runs, the glow plug comes loose and it eventually dies.
I had it going to full power pretty good yesterday, but I shut it down because of the foaming.
Today the engine was just weak. At full throttle it felt like idle.
The glow plug is fine and the head screws are as tight as they will go.
Whats wrong with it?

Oh yea, it also spitting out fuel through the exhaust(which is normal, but there seems to be more than usual).




Thanks!

Sounds as though you have not peaked the needle valves and then set them correctly?

Enjoy,

Try taking an alan wrench and insuring all of the bolts on the engine are uniformily tight. They do not have to be excessively tight, just nice and snug. Insure the carburator is seated all the way against the crank case and insure the glow plug copper washer is installed.
