Well for one I did not recomend him to do it so he should use his own judgement. if the things drippin with fuel he sures got problems. And anybody with half a brain i dont think would do it if its that saturated. Like i say I have used this method on gas soaked chainsaw snowmobiles have fumes inthe bellypan and lots of fuel spit out the carbs with quite a bit of fume
and never had problem. Everything in life can be dangerous he could pull the motor over and the rod could come through the block and kill him just as easy. Like I say I did not reccomend him to try it .just telling him how I do it. I think it would have to be pretty air tight to hold enough fumes to go up. But thats just my opinion Dave
