I had an issue with the intake I got with a Polini kit ...it wasn’t completely flat on the mating surface ....which caused an air leak.... which made my Moped go faster than ever and seize!

I built a new bottom end and ordered a new kit that was just a cylinder only deal .... same thing happened....

I wondered where the sand or stuff was coming from ....

It was coming in from the intake seal at the head above the reeds....

I used some 1000 grit sand paper and a flat polished piece of marble to sand the intake flat and it hasn’t caused an issue since
