GRP... test run number two coming up! On my first run my carb got stuck somehow, but good old Drake gotter going for me again. Thanks Adam!

Anyways, I ran a P3 OS plug (per actual words from Mike Truhe mouth that it would work) and the motor seamed ok. But I want to know what carb insert you guys are running? I think I had an 8mm or stock one the first time out. It seemed ok but it was a bit hard to keep my tune. If I run this for the Nats, all I care about is run time and bottom end. High power motors just get me in hot water too fast! My modded RB C6BBT7 is just too much power, so I'm hoping to get the GRP smoothed out.
