won't it take air there ??
I installed a micro fine o-ring there just in case...
There is only one o-ring on the crankcase below the carburetor to seal up the air. It no need another o-ring if the sealing o-ring is in good condition.
If you use 16% nitro,you can use 0.3mm head shim. Want more punch use 0.2mm shim. If 0.2mm burn your plug(coils pushed),change back to 0.3mm.
Use long body normal plug #5. It has the widest usable range.
If you want to use Turbo head button,use #6 turbo plug.
