[Timing Set, and it seems worse >.<!]

ok so... I'm having issues! I had my timing up to 30+ before I actually had time to get a timing light in there and set it on advanced 13. but now that I have it set on advanced 13 I'm wondering if it's not getting enough gas, and if that's the case I would need to up my power valve in my carb.

 

I'll list the symptoms here; when going between 0-15 mph it doesn't wanna accelerate, when I come to a stop it likes to die if I sit longer than 4 seconds, and if I punch it from a stopped position it sputters and tries to go then dies.

 

Any help is appreciated!

 

P.S. 355, .30 over pistons, mild cam, +13 timing, 650 Holley Carb (made in 76), smallest power valve for the 650 carb (I do have about 2-3 extra valves sitting around).

hey, I actually had a similar issue about a week ago. I kicked off my edelbrock quadrajet and threw on a 650 holley. I know you're going higher than a 650 but this may also help. Basic rules of carb switching, Check all Vaccum lines, floats, and also check your power valves to make sure you're not flooding out your carb. I had a power valve that was to large and I had to drop it down just so I could stay running. also, Most of everyone here may know this and is well experienced with cars but, Those vaccum lines at the back of the carb running to the master cylinder.... yeah those are important too... ahaha... I didn't reconnect mine at first and tried to seal it off.... Don't try it... not worth it! besides all of this. if it's not a new carb, simply try rebuilding it *shrug* couldn't hurt anything more than your wallet, and the engine/carb if you rebuild it wrong O.o I trust you though, I mean hey, you were smart enough to ask these guys

 

hmm, in hind sight, none of this may relate to you because the carb is from '76... and I still have the original engine in the '72... soo if you're running something newer, I'm sure it's different X.x
