Carbuetor Issue

I just rebuilt my motor last year and have a 1406 carb. . I was having hesitation issues and had 3-4 plugs always looking rich and the others fine. I also put on a NEW rebuilt dist., flame thrower #3 and module.

This year I brought back to my mechanic and we did a compression , leak down, manifold smoke, valve check and everything was fine. So I decided to try a new 1411 carburetor and follow Jason blog to a t. Plugged gutter holes, bought insulator spacer and away I went.

Started the car and found the car with less power and still hesitating? So I pulled off the carb and found the insulator front holes seem to be about 1/32 too big for the manifold? We also noticed that the gasket was soaked and the gutters were full of fuel.

Can anyone help.

Thanks

Dominic

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments 0 Likes

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,
