No performance/ bogging down issue

So I got a real stumper going on. I rebuilt my Qjet and put leaner primary rods in to fix a rich condition. Also replaced my coil, cap and rotor to fix a miss. So for a month everything was running well. Took it for a cruise night and it was running great. Lots of power, no misses, nice and smooth. Parked it for a week and then no power, bogging, barely running.

Check the dist and it is tight, so that did not move.

Figured it had to be fuel related. Put 5 gals of fresh gas in, no change. Checked the fuel pump, 6 PSI (mechanical). Took the carb apart and the float was stuck to the bottom of the well. gas evaporated and residue glued it down.

So I fixed that and checked everything else inside the carb and it was fine. Put it back on and it started up after the bowl filled. I can rev it and 80% of the time is fine, but I still hear it struggling. When I put it in gear it starts to die. When it warmed up, it dies at idle.

So what do I look at now? I feel it is still fuel related. I measured the psi after the filter, but before the carb. Very disappointed!

Re: No performance/ bogging down issue

Plug wire? Fuel line? Could change back the primary rods just for grins?

I feel for ya brother. Hate this stuff...usually it's really simple yet it takes us a while to figure out.

Re: No performance/ bogging down issue

Did you check the points (assuming you don't have HEI)? I had my distributor rebuilt last year by Jerry McNeish and it was set up perfectly-dwell was right on. The car ran fine after it was installed. I took a couple of short trips and the car ran great. Got it out this spring to take it for an inspection and alignment. One the way home from the shop it just died. After trying a bunch of things, I pulled the distributor and when I was rotating it, the points were totally closed. Reset them and it seems to be running fine now.

I have a couple of friends who own shops and they both said it is really hard to get good points and condensors these days and they have seen similar problems.

Re: No performance/ bogging down issue

Thanks Rich, dwell is fine. Pulled the carb abart (again!) and did a closer inspection and found a small piece of evaporated gas residue in the primary jet. It was not blocking the hole, but from preventing the primary rod from closing the hole under high vacuum cause a over rich condition. Fixed that, running smoother and can rev again. But new problem, when I put it in gear (200r4), it slowly loses revs and dies. Tried adjusting idle screws and idle speed, no change.

Idle is at 1200 in park, but it in gear, lowers to 8, then slowly goes lower and dies.

I looked at the idle slots when I had it apart and they were clean.

Re: No performance/ bogging down issue

DOH! I must have screwed in the idle mixture screws in too much during my playing. Backed them out to 2.5, then 3 idles well in gear now. Still have to change the plugs now.
