Fmf calls for a 260 main, by itself. Premix up, foam filter up, lid removed up, but these are estimates a plug chop is necessary to confirm. Temps and elevation play a role as well. 250 might be ok if everything else is stock, but again only a plug chop can tell you.

you will need something better than a 250 then. you should be at 270-280

stock oil injection or pre-mixed gas?

you need to leak test your engine too

I pre mix my oil and I was wondering what do I need a leak yeast for

A leak test is to make sure the engine isn't pulling extra air, there's lots of threads on here about it, just search. Whats your elevation and temps
