Hey evryone,this is my first post here and im extremely desperate for help here as I plan on racing tomorrow and cant figure out my problem.I have a Go 3port in my Hyper 8.5 and had a bad accident at the track today.I went over a big jump and scraped the wall on the way down.In the process I broke a few of the fins off of my cooling head and snapped the HSN off.I replaced the HSN with my MACstar .28 needle.My buddy who ons the track has a 21 5 port and gave me his head (grey) because he got an after market one.So i get everything hooked up and when all 4 tires are on ground and I try to move the car the flywheel wants to spin with the car.So in a nutshell.I try to move the car and it wont move due to the flywheel moving with it.Any help soon would be awesome and greatly appreciated.I dont know if its the shims or something other than that.I have 3 shims on there.Also,I changed glow plugs to a Mccoy mc9.
