I hooked-up a kick-down cable, but it will not work. I don't know if the carb linkage is just not pulling it out far enough or not to engage. Before I try to rig it, any ideas why it's not working? I unhooked it temporarily to see it affected the problem listed below.

Also, my engine bogs down from standstill and when I step on it at pretty much any speed. I can gradually press the gas and it will pick up pretty good. Just can't step on it at all! I noticed if I dropped it manually into 2nd when it started bogging down around 40 or so, it pushed through it ok. I'm still suspecting carb problems, but I previously switched it with another rebuilt one and it does the same thing.

Another thing I might add is that I replaced one of the heads due to valves sucking through. I looked at the other head with the cover off to see if the stems on it were any lower than the others. I didn't see any sucked in like the other head. This was a rebuilt Autozone engine. It still only has less than 10,000 miles on it!!! The warranty ran out due to time, not miles. I've had nothing but trouble since I got it!

I've tried all timing settings, put in HEI distributor, had the carb adjusted by mechanic, all with same results. I even gapped the plugs more (I didn't know they had to be gapped different when going to HEI from points).

How can I tell if valves on the other head are ok without taking head off?

Thanks,

Losing my mind
