n20 and timming

ok well. plans are in place and parts have been ordered to finish motor on the gas.
total planned shot is 150. ( kits smallest pills = 100 )
-upgraded to Scat I beam rods for added insurance (good thing its still on the stand)
-5 gallon fuel cell and equivelant electric pump
-step down 1 heat range .030 gap on plug (also find a shorter plug) the plugs i have stick way out.
-initial timming down to 28* to start
-looking at VP100 (street blaze) fuel all the time due to CR, but will try the 50/50 mix and see how it starts and runs.

thanks all,
im still taking comments.... fuel, spark plug specifics etc.
