I have just purchased an 83' Rabbit GTI, that I will be running in ITB in the SEDiv. This car was last ran about 2 yrs. ago. It had a pretty bad exhaust leak & the guy I bought it from said it was down on power, the last time he ran it. The motor had just been built about 2 races before he quit running it. I figured it had a burnt valve, so I pulled the head & had it checked. No valves were burned & everything else looks good including the bottom end. It has good oil press. Wondering if it could be timing? The head has been shaved & the timing seemed to be off. I have a manual & can't seem to figure it out. The lower pulley has no notch in it to line up the dot on the intermiediate shaft pulley for the distributor. I did notice the distributor didn't have the vaculm advance hooked up. Is this normal? The injectors look good & clean. Has anyone else had this problem? Thanks in advance.
