Chris,

Sounds to me like your oil pump is dry and isn't primed.=A0 If I'm = correct, the only way to get it going is to either take the front cover off, remove = the pump and prime it with Vasoline (I think that is what Lynn recommended), or pressurize the crankcase with 3-5 psi of air while cranking the engine over= to try and force oil up into the pump to get it to prime.=A0 That's what I= had to do to get my 20B oil pump going.=A0 Maybe someone else has a better suggestion.=A0
