During my 1-2 shift, the car seems to have a slight hesitation/stumble and I have no idea where to start troubleshooting??? It didn't do this last year. I've got a new carb and a more than adequate fuel system this season. It's almost like it cuts out for a 1/2 second as I shift to 2nd gear. It doesn't do it on the 2-3 shift. I'm stumped on this one :confused:

could it be your float level ? or would it do that out of the gate too.. and you said it only happens on 1 to 2. ????? dose it do that on every pass?? :confused: :confused:

It does it consistently on every pass, every 1-2 shift and that's it. When I removed the distributor cap tonight, there was a lot of white corrosive build-up on the contacts and on the rotor tip. Wonder if that could contribute to the problem???

Patrick suggested to increase my fuel pressure by one lb. It's currently set at 6.25 lbs, so I'll bump it up to 7.25 lbs and see what that does.

Replaced the plug wires, rotor & cap. Hesitation is still there. Looks like I'll start looking at fuel delivery.

Do you have a fuel pressure guage you can see when driving the car? Mine used to be mounted on the cowl panel and I could watch the pressure drop on acceleration. Mine dropped to the lowest during 1st and 2nd; I guess that's when the g-forces were the greatest.

Yeah, mine stays rock-steady the entire pass.

Where is your guage tapped off at? I looked at the pictures you sent me I don't see it.
The gauge is plumbed in between the regulator and the carb.
