Years ago a fellow in the local club had a wagon with a 140HP with PG and he complained it would not run well due to timing issues. Either it would ping a lot, or reducing the timing would make it loose power and the fuel mileage was awful.watersrl62 wrote: ↑Tue Feb 27, 2024 9:24 am Thanks to everyone who replied. It is a 1962 Monza Wagon, engine currently has a 4 carb setup, power glide trans, white body, burgundy roof. It has a custom burgundy interior, custom front grill, custom brake lights. It has a white body with burgundy top. Both will be repainted once I complete rust repairs. Let the fun begin....
The problem was a 140HP manual transmission distributor! The LM Corvairs equipped with a 140HP and PG were different. One thing was a revised distributor curve. I found the 110HP distributor was close in timing to the 140HP PG distributor, except the static timing was 2 degrees greater. I gave him a good 110HP distributor and he set the timing 2 degree less at static for the 110HP distributor in LM cars. It solved his problems. The engine put out more power and NO pinging.
Not saying you'll have the issue, just something to know. When you have time find the distributor number and we can tell you what engine it is for. Enjoy the car.
