Howdy guys,
So I'm at wits end here with this 2100. It cruises at 14.7 on the highway at 60 in 5th (so good). But it requires I run a rich idle (11.8-12.2). I set up the choke per the rebuild manual then by how the 4100 is setup (YouTube video i found). It likes to run extremely lean (14.5-15) when choked and requires 2 pedal stomps. When I go around left turns it leans out past 18. When its cold it likes to die when i come to a stop (leans out past 18). When its hot, and I rev it to about 2000 in neutral, it leans out to around 16-17 and stumbles bad.
I'm about to raise the float a little more but I'm running out of things to do. I do have the PCV hooked up but it did the neutral lean out before. Currently I'm running 54 jets. The idle mixture screws are about 2.25 turns out. The idle is about 800-850.
I'm pretty sure the neural lean out and the lean cold choke are related. Maybe jets? Next size I have are 56s.
For those that don't know, i have a 200, 2V 1980 head, 1.75/1.5 port flow valves, 256H Schneider cam 2 deg advanced, dual out headers, 1.08 1968 2100.
Very much considering putting on this Holley 2300 350cfm i have. The last 2100 i had had weird issues and never ran right, so this doesn'tgive me fuzzy feelings with the current one. The only thing keeping me from the 2300 is that I don't where to start jetting wise.
Am I better off to figure out the 2100 or go with the 2300? If I'm better off with the 2100, what do you all think it could be? I've made damn sure there's no vaccum leaks. If I'm better off with the 2300, whats a good place to start with it?
Thanks guys
Ryan
