Thanks everyone!!! Hopefully my luck continues this next weekend. Mac65 you have a nice set of tires on that mini mod. I always found the tires meant alot with those. That is biggest negative about pulling, we only get one shot at it week to week and no testing time in the middle. I can't rememeber how many say their engines ran great in the garage to see it sputter and die when hooked to the skid. We r still playing with the barrel valve with this engine. Seems to want to bog abit at the start then comes to life.
