Really bogging down in 3rd gear

- Auto trans? 3 speed? 3 speed

- Is the car revved up a lot when it shifts, or just normal RPM's and speeds and cruising? I have to rev it up going from 2nd to 3 rd

- Does it run better in 3rd when you finally get it revved back up? No, it still is boggy in 3rd when it gets going

- Does it bog after shifting from 1st to 2nd? No, honestly it jerks and bumps from 1st to 2nd

- Is the timing setting at idle per the timing cover tab, and is timing set with the vacuum advance hose removed from the distributor and plugged, and using a timing light? Yes its set on the timing tab using a light set at 8 deg. I cant remember if iplugged thehose when i timed it

- Is this an older points distributor? Yes, new points replaced several months ago but part of what i plan on doing is new points

I would be thinking carb's power valve not working (you have a Holley 1920, right?), ignition timing (perhaps mechanical or vacuum advance not right), overall timing (basic ignition timing, or timing chain, but not likely just the chain as it would be doggy off idle in 1st and 2nd too), or fuel restriction. Answers to the set of questions above will help narrow this down.

Its a new carb. Not a holley. I plan on replacing plugs again i had lots of touble several months ago getting it to fire and run...180 out, etc, timing back fire. New cap and button. I am oing to replace the fuel filter again and reblow outthe lines. New tank also.

Thanks for the help. Merry Christmas
