Swapped out my carb for a professionally rebuilt stock one. I also swapped out most of the vac lines with silicone ones. When I turn the key and pump the gas twice (activate electric choke) she'll start up and idle smoothly but when I hit the gas, she stumbles and dies. I've gotta wait a few minutes or else she won't even start up again after. Wondering if this is carb adjustment or whether it sounds like I mixed a vac line up, possible but I tried to be careful. Bowl looks about half filled.

 

Well, I left a vac hose off... Duhhh- and now I can't figure out where it goes. Anyone know?

Big one, closest and going to the left

 

If you are talking about this hose, I think it connects to the air cleaner.
