Finally got it running good. So today I was looking for vacuum leaks, didn't find any but swapped out the brake vacuum check valve, after doing that I bought vacuum caps and put em all over the carb. After doing that I decided to take the carb apart and mess with the float level. When I was...
Here you go. Not much to see really besides my crappy relay wiring for the HEI (this is just roughed in for right now until I get it running good, then I'll secure the wiring).
Unfortunately I installed the carb and HEI at the exact same time so I'm not sure which is causing issues. All of my troubleshooting thus far has been HEI related so I think I may switch to looking at the carb now. Thanks for the info I'll have to check it out and let you know what I find.
Had a little bit of time today so I decided to check what voltage I was getting at the HEI, it was at 6 volts. So I tried to trace back the wires which led me to the plug that connects the fuse box to the engine bay which is so old I didn't want to risk breaking something taking it apart. So...
I was thinking of doing this initially but my dad didn't run a new wire on his 350 when he put a HEI in and it has been running for the last 25 years that way. Makes sense why this would cause issues though, I'll have to do that next. Thanks for the info
Come to think of it when I was setting the timing it seemed to run better the more I retarded the timing beyond 4 degrees before top dead to a certain extent. I'll try the things you are mentioning and let you know what works when I get it running good. Might be a few weeks out on that though...
I haven't thought of vacuum check valves so I'll start there. I'll have to check out those websites you were telling me about too. Thanks for the info!
Hey guys I have been having a weird issue with my 1973 Chevrolet C20 with a 292 straight six and 4 speed manual with granny low. Just installed a new single barrel carb on the original intake manifold and a HEI distributor. Got the timing set to factory setting (4 degrees before top dead center)...
