I hit the gas it does nothing for 1/2 a second then goes, or it pops and backfires, and has died a few times. If this were a 2 stroke i would say LEAN! does this apply to 4 stroke as well?


Do you have access to another carb and can you set total timing at 34 degrees? base timing doesn't really matter with this topic you need to know where it is at 2000-2500 and the base will be whatever it is twocents
At this point in your process you have to rule out ignition or fuel ratio so you know what it isn't shruggy

the only other carb i have is a 1050 dominator... that won't help.


on 2nd through i have a 650 holley on a SBC... runs great on a very mild 350
i need to get my other timing light from my parents house to set total timing, ill try to do that soon.


Is your current carb a vacuum secondary variant or a double pumper? It looks like a vac sec from your pics. Have you done any "performance mods" to your carb?
