tunning help

I have a early 1970 California GS 455 4-speed non staqe 1. Motor has 76,000 miles, new points cap wires, condenser, coil, carb rebuilt. Choke seems to be working. hates to start cold. Warm starts good, under power runs good, steady speed has a slight stumble. Where do I look? Thanks Mark Rehr

 

check the dis. for to much timeing with vacum hose hooked up:beer

 

Chek your primary shaft in the q jet for up and down movement and side to side.

 

Thanks for the help, I put the old cap and wires on and it runs great. So much for new, Will find out if it was the new cap or wires. Old ones dated 1975 works great.
