Hey guys,
Got the timing adjusted properly this weekend...it is right at 8 degrees BTC. We also adjusted the valve lash (we had done this before the timing issue). Also adjusted the dwell again and it is right on. Running better, but still a little hesitation/missing at idle and with the throttle up to 2500-3000rpm. The hesitation/missing does not go away at higher rpm. It warms up fine. I drove it, and it hesitates a lot when I step on the gas. If I accelerate very slowly, it seems to be better. Feels like it should have more power as well. Still smokes, smoke is a whitish blue, but it doesn't smoke all the time. I'm thinking that ggzilla is right about adjusting the carb. The manual calls for adjusting it in drive using a CO2 meter (which I do not have). Is there another way to accurately adjust the idle mixture? Also, could it be valve problems?
Also, when I bought the car, it has a stuck intake valve on the #2 cylinder, and a bent pushrod on the intake valve of the #3 cylinder. It would not start until I fixed these issues, obviously. However, now I am wondering if the valves leak a little, possibly causing the blue smoke and hesitation. Could this be a possibility?
Thanks again guys so much for the help. This is the only place where I can find people to help me out on my little Datsun.
