It does not use oil and plugs dont foul. Also has black oil come out exhaust tube and muffler. Is there anytype oil i can use that will not smoke so bad. Does not hurt anything except smokes building full of smoke. [Reply]   [No Email]

Replaced the plugs today they were all a little oily but not fouled beyond firing. I guess i will just let her smoke kind of embarassing in public. [Reply]  [No Email]

No such thing on MINE...????? If that diaphragm involves an oil line, I would suspect it is feeding oil to the fuel.. Your Pony is stated to have something like 10 Wt oil..not positive, but I know it is not supposed to be more than 20 Wt.. Are you sure the Breathers are not plugged..?? Ron.. [Reply]  [No Email]

Is it really firing on four cylinders? The starting engine should be able to rotate the diesel under compression continuously with 0F outside temperatures. Many times I see starting engines at shows that are claimed to be 100% but will only slam start the diesel if your hand eye coordination is quick. [Reply]  [No Email]
