40:1 sounds ok, unleaded is ok too but my fizz used to get a bad virabtion when you revved it hard and using unleaded gas.

Use a higher grade unleaded like Optimax or real 4 star gas.

Enjoy !

I have just burnt a hole in my piston my FS1e and I am thinking it is to do with me putting in unleaded fuel with fully synthetic oil at a ratio of 40:1 does anybody know what it is meant to be?

Cheers,

Ross.

lead replacement additive and a mixture of 20-1 would probably solve your problems
