I've had my share of problems. Oil line Fire, the worst(all burnt wiring repaired except fuel gauge wires),727, pan leaks,(mopar gasket fixed),belt alignment(pressed WP threaded flange fix),stock air cleaner to Holley DP HO 750 carb(1/2in adpt fix), dialing in the big cam and carb to work with the mild(1800 stall, 2100rpm flash converter), carb benn off 20 times for changes, it finally got time for some short test rides! Drove several 4-5 mile slow(3500rpm max) test, returned for adjustments. My 10 year old son(I'm 62), loves off road, was with me yesterday, and on several other test. Almost home he said, it just don't run like it did when it was in the car dad. Now it's still choked down with only 2in cherry bomb style pipes, and the single valve springs still on(I have triples to install,4500 max untill), we left the last stop sign turning right,1/4 mile from home, I laid into it hard, Lit the rear tires up for just couple seconds, tact hit 5k before I could get out of it, he grinned ear to ear,said now that's what I benn missing. Springs going in soon, then going to muffler shop to uncork, I think I'll be happy.
