Falcon006

After the rebuild it’s running a lot better. I still have a little backfiring during shifting. I think it’s from the lack of a dashpot. Besides that she is running great, except for the fact its a lot harder to start in the mornings ;-). Guess my next project is getting a choke cable. Thanks for the support all.

I have just recently bought my 240z. I bought your carb tune up video, which help a lot, and was able to rebuild my carbs. I used a cheep 20 dollar rebuild kit from autozone. This only had gaskets and fuel line. I decide not to use the needle/seat it came with because it broke while trying to install. I reused my old ones. I'm pretty sure this might be causing my richness problems but I was wounding if the N45 needle or nozzles could also cause my motor to run rich? I'm most likely going to buy the needle/seat and SM needle from Ztherapy . Should I also replace the nozzles?

I just recently bought a 240z! (1972) I tune up the basics ( points, caps, plugs, ect..). Now I’m trying to get the carbs to balance. The airflow between the two carbs are extremely off. I’m getting 2 or 4 times more airflow on my rear carb and hardly any flow in the front. I thought it could be a vacuum leak, but I check it with the starter fluid trick. I haven’t top the SU carb oil yet and I haven’t check the valve clearance ( Should I?). Do i need to rebuild the carbs? I’m pretty new cars . So be kind to me.
