^ Mine is cold to start too, same thing. ralleybmx, if you were the guy with the orange wheels in pro buggy at the Hut today, I am talking about you. That thing was nasty. Honestly, besides Steve running that .28 Rossi in his truggy your engine was the baddest out there. At this rate, my engine is going to be junk by the time I get it tuned right because you're race prep is like twice as fast as my full mod. How is this possible??? For now the compression is good enough that it will pass the 3 o'clock test with flying colors. I'll throw some more P5's at it...For now I am going to put the JS in my buggy because the mileage sucks on my Orion. A little bit of a rant here but I am sorely disappointed that I can't figure out how to get my engine tuned right. Good racing by the way! You coming back to the Hut any time soon?
