Hi guys,
Six months ago, I bought a 67 289 2v autolite coupe with a C4. I love it. However, it did sit on a lawn chair for more than 15 years without really running...
After all the hard work on the body, now I'm tackling the mechanical aspect and have come up with two problems
1. The car is hard to start, requiring 5-6 GOOD pedal pumps and some cranking to start. Also, after it starts, when we give it gas, it stalls or bucks and burps. It idles very fine though.
2. Although our test drive was in my neighborhood streets and we did not go over 20mph, the car does not seem to shift into second gear.
My obvious questions are: how to troubleshoot these problems.
a. We already verified that the accelerator arm does move and does inject ''some'' gas when we push on the accelerator pedal. However, does it inject ''enough''? Is the accelerator arm on these things adjustable? Could the float bowl be the culprit?
b. I checked the transmission oil level with the engine running. It was very full. Slightly past the ''full'' line. Could the vacuum modulator be the culprit?
I am sort of a newbie at this stuff, but I love to learn and am already hooked at finding the troubles and resolving them. But I admit for these two problems, I'd like the insight of experienced people...
Oh, as a final question. If it comes to replacing the autolite 2v carb, should I go for a 4v, higher CFM unit? I will be replacing the heads, intake, cam and exhaust this winter, but would like to have a clean running car this summer... Can a stock 289 run fine with a 500CFM 4-barrel carb (for example)?
Thanks guys...
Pete
