We use Cummins G series. They burn natural gas and have spark plugs.

 

Is anyone using the version of this plug with the little lever for releasing the oil? I think they called it "finger touch" on geno's website.

 

I have that one. I like it, its out of the way up behind the axle. I put a small hose clamp around the body of the valve and it stops any accidental drain.

 

WVAussie, I noticed you said you put a hose clamp on the valve. Doesn't the lever have a little indent that it rests in until you open it and is the lever just simply too easily dislodged to an open position that clamping the outlet off was necessary?

 

yes it does have a detent and I think that would work just fine. The reason I put the hose clamp on is I've got 4 boys and experience with them.
