Hi,
My mods are stock motor 2nd oversize
-Trail porting on cylinders
-Top end is fresh, has about 2 hours of run time on it
-Trinity pipes
-Cool head with 21cc domes
-Chariot performance intake manifold
-Stock carb machined out to 28mm
-Dual pods with outerwears
-Timing advance +4
-Running on 91 Octane 32:1 mix with AGIP 2 stroke oil
-BR8ES plugs gapped at .020
I am at sea level with 27.5 pilot 300 Main, air screw out 2 turns. Carbs are synched.
My issues is that it pops at idle. I know usually this is created by a rich mixture and I believe that is the case since the plugs are wet when I pull them out after a minutes running at idle. I pulled out the air screw to 3 turns which did not change much. I then swapped for the 2.5 pilot 1.5 turns out on the air screw and its still popping and with a new plug after 10 minutes of idling the plugs are clear and wet...
I have a Nology coil just to make sure spark is good.
Do you guys have any ideas?
Thanks,
Mark
