I messed with my dual Carter W-1 set up again today. The truck runs really good once off idle and at full throttle. The problem is with the rear carb still not idling right. I have cleaned it three or four times now, studied on it and compared it to the front one, I just don't see the problem.
These are 483's.
I am down to the low speed idle jet tube being bad, it doesn't look very good and I tried to flare the end, but his had no change in idle quality.
Looking down the barrel when running, the fuel is dribbling out, you can hear each drip hit the throttle blade, the front one is mix fuel and air correctly. With just a slight choke, the rear carb perks up. I spent 2 hours turning mixture screws and idle speeds trying to find the right combination. This week I will swap front to back to verify the carbs or intake problem. Vacuum is a steady 20 inch's with the throttles open some, I don't have a full time vacuum signal except the PCV so I still need to check the vacuum at idle once I Tee into the line with my gauge.
My Uni-sinc gauge doesn't seem to be effective on these, if I set it to float the red ball, the engine will die, it needs to be at a high idle to get enough air passing through, this I believe goes back to the rear carb not acting right.
Any thoughts?
Any body sell internal parts for the W-1? I haven't found any one yet.
