have ? for u all. i have the eb mod version. i ran maybe 3 gallons. i think the compression is low but not sure for this motor. i cant turn it over by hand with a lil force. i run nova motors though and i cant do that with them. motor runs like bat out of hell no problems. was thinking it needs a pinch since it feeels like this. are these high compresion motors? just trying this one as a experament. thanks for any insight. also if u all say it needs a pinch or new p/s will the version 2 p/s combo fit the version 1. if somone could pm that would be great. get busyy and forget to check form talk thanks
