Oil line dosent go in the front like that, thats the crankcase drain plug. Oil line goes into the hole in the top of reed valve plate on the back and.just drips in and oil gets sucked in with the air flow
Re: M type petter oil problem

thank you very much mick i will have alook soon that is where it was when i picked up the engine also any idea approx how many drips does it need per minute. thanks.


I run my engines at 10 drops / minute. At the moment we are not driving anything so they just tick over at low rpm. If that sounds excessive I don't mind or charge for 'weed control'.
