>Checked the ignition
set to stock gap can you adjust timing?
> Choke rigged backwards?
chokes not engaged no idea if it's backwards
>Impossibly small idle jet?
35 some letter and yes it is tiny. but i have no comparison o wait i have a stock idle jet i'll see if that is bigger.
> Missing main jet holder (jet sits too high in the bowl)?
i have a main jet holder
> Slide needle taper/length completely wrong for this engine/carb?
it's a four stroke needle, should i just do the ghetto trick and grind down the end?
> Clogged idle jet, air screw adjustment off, clogged air passages (I
know it's new - just sayin').
clean, i do keep rechecking to make sure i didn't miss any thing. and i'll try fiddling with the mixture screw and needle adjustments tomorrow?
> 20mm is oversize for that engine. 18/19 would be more appropriate.
a 20 $ carb is hard to pass up on and i come from 2 stokes people run 20's on 50cc one speeds...
>You've built a C90 engine with the 88 kit.

> Only thing is - your C90 has too much air intake and too little exhaust flow.
