I got a cordless Dewalt cutoff tool and a 20 gal parts washer for the shop.
I bought myself a slightly used Demon carb. A fella bought it new, put it on his truck, fouled the plugs idling, and swapped it out for a new Holley TA. So I've been busy excising it here lately. Though I think I just about have a tune now. I had to drop the jets 4 sizes in the front and 3 in the rear to get it close. I swapped out the 31 squirter with a 25. Now the idle circuit needs to to be leaned out a bit more. I'm going to try larger air bleeds first. If it will not lean out I will have to bush the idle feed restriction. Barry Grants tech people say it will be rich at idle if you don't run at least 15* of base timing. I guess that is there excuse for an excessively rich condition. Fuel is too expensive to be spitting it out the tail pipe right now...
