In every gear I grab It starts to sputter at the very beginning of each gear. I just put a new disty, rotor and spark plugs in and I can't figure it out anyone got advice?

 

What's your RPM when it happens? Checked the timing?

 

It's 1000 rpm after that it quits. but when I put my weber 38 on I never checked the timing?

 

1000 RPM sounds to low to start a gear. Are you sure it's actually miss firing not just struggling to accelerate?

 

Yeah sorry it's about 1500 to 1700 then it smooths out. The 4.88s help push my 33s great but I get that sputter when I first take off.

 

1st gear doesn't do it but 2-5 does.

 

Did you set the timing when you installed the distributor?

 

Yes I had my buddy do it while I was at work maybe I should check it.

 

Check timing first. New 38 or used? Used could have bad accel pump causing it to starve when you give it the skinny pedal. If new it could be that it's dumping too much fuel and flooding it a little (especially if you're down at 1000rpm on new gear and flooring it?). Any backfireing? Or just sputter/hesitate? Anything when giving it gas at higher rpm's and not shifting? Try rapping it out a little more before shifting and see if it makes any diff.

 

New 38 and just sputters when I'm barely in the peddle it runs fine when I rap it out and shift at higher rpms. It just does it when I'm barely in the peddle.

 

And no backfire.

 

Sounds like you're just lugging it a bit or it may be a jetting issue. Oh, when you installed the 38 did you use the redline 2 piece adaptor plate? They're notorious for vacuum leaks. How's the idle?

I've had a 32/36 on my truck and currently have dcoe's, but have never run the 38, so there might be something paticular to that carb with low rpm and low throttle that causes this.

Maybe someone with a 38 will chime in?

 

Do you have a fuel pressure gauge and/or regulator on there? Just running straight off the stock pump?

 

Yes I have a regulator and it idles very smooth like a champ. I'm also running a lil rich. And yes I have the crappy two piece adapter and I've torqued it down twice already but I checked for leaks and didn't find any.

 

Oh and the fpr is running right of the pump.
