why carnt u run 30% with .6 .7 clearance will it detonate, or u can u just carnt run the higher temps
gee the alpha must have some clearance out of the box
the novas are just designed the way they are and the alphas are designed the way they are , the head buttons are just machined with different tolerances thats all
you can run 30% fuel with .6 or .7 if you would like but the engine will last longer and run smoother with much better runtimes with .8mm and 30%
at nats i would run 40% with .75mm or .80mm , tuff to make power at 5500ft elevation
the engines now come with2x.30mm alu. and 1x.20mm copper instead of 2x.30mm alu. and 1x .10mm copper
thats what i am saying
