I am finally road testing my 2.0 restoration and haven't quite got it right yet. It starts fine, runs smooth idling or revved up in the driveway but on the road test it accelerated slow, with what sounds like valve chatter when I give more gas to accelerate. It wouldn't go over 3000 rpm in 1st, 2nd or third. I tweaked the timing a bit and it seemed to get better, less chatter and almost up to 4000 rpm. Suggestions, comments; am I on the right track?

Yes, "ping" is what I was trying to describe, sorry for the vague terminology. By tweaking the timing, I changed it from about 22 degrees to 27 degrees (as indicated by the dial on the timing light) by rotating the distributor. I had originally set it a few years back (2015) but I have removed the engine a couple times since then due to major oil leak and transmission issues and was suspect of the timing when I heard the "ping".
When I began the restoration (2006), it had carbs. It is now fuel injected. I bought another 1974 2.0 with severe body issues for parts and a second set of FI components for a 1974 2.0. I picked the best of those to put on the restore, trying to keep things compatible using a document by Paul B. Anders I found on reenlist. A little more of the backstory; I shipped the engine to Arizona to be rebuilt (by Greg Robbins) over 10 years ago. He put in 96 mm Keith Black pistons and Raby Cam kit, so it's about 2056 cc now. I added a couple before and after pics. |
