Had to rebuiled the top end of my 2.0 ltr engine, had bad rings. Installed new
pistons and cylinders and did a valve job. Just tuned my engine on my sons
Dyno. Instaled 32MM choke tubes and change the main to 135 on my IDF40's
Engine now dellevers 93.35HP at 108.65 lbs. of torque with a high lift cam.
Engine started out with 76HP at 99 lbs. of torque what a difference now.
