Post Problem starting

Here's what it's doing, I start it and it dies, I try again and it won't start at all, I keep trying and then it won't even turn over, just clicks. I give it 10 mins or so and it starts but very rough at first and then smooths out. I'm guessing it's flooding but why would it not even turn over and then later start right up? Even when it does start right up it's rough at first. The carb is a Holley 750 E Choke fresh rebuilt and fresh rebuilt HEI, any ideas? Thanks.

if it was running before the carb work was done? then one would guess that someone messed up? pull one of the spark plugs after it dies and see if it wet or dry?

I bought it from a self called "Holley Expert" He did the rebuild. The first few days were fine. If the plugs are wet what does that mean? Thanks.

I know that LOL! What I meant was what to do? What to check? Just making it leaner won't solve it would it? It's a rebuilt 350 .060 bore, Hyper Pistons, 9.5-1, Victor Jr Intake, 518 lift Crower Cam.

I believe you have to much carb for that engine! if your are street driving it? you are going to have lots of problems with that holley! much like the trouble you are having now! a holley is good if you are racing it? if not? i recomend you go to and edelbrock for street or find a good quadrajet, if you insist on a holley? then go with a 650 double pumper with vacume secondaries.

I know you're right, I had a Q Jet on there but it had a few problems. The Holley people told me I need the 750 for that cam but I can tell it's too much.

I would check the float levels. I had problems with a Holley until someone told me to check the rear float. Voila!

If you have a double pumper with vacuum secondaries...I have to see it!!!

One nice thing about the Holley is it's easy to work on. I checked and set the floats, it didn't seem to help.

it is possible to use a 750 on a small block,but as set up in chevy power performance book but it still would give you street drivability problems.

nothing wrong with a 750 vac secondary on a small block thats the beauty of the vac secondaries, you can't overcarb. Check for a blown or wrong power valve or wrong float settings or wrong or plugged idle bleeds, most of the self styled holley experts i meet aren't all that. as the kids say. I went to school for Holley way back when they were owned by Colt industries, and i still see some interesting modifications by "Experts"
