Joejr915 Posted March 3, 2012 Report Posted March 3, 2012 Working with a 543 cheetah. Just put together my new motor and fired it up. When i rev it up it sounds like something is holding it back or like something is tight. It has 39 pwks with 52p and 175m. Timing is 90 thousands with a pvl. Squish is 56 thous. I pushed the kicker down with my hand its not bad about the same as my 4 mil. It sounds fine when its idleing. Cannt figure it out. Any info will be helpful. Thanks Quote
