Rough running issues - kinda long

[scottbr997]

I have a 73 with 200-6 with Carter YB 1B. Sat for ~22 years. Took carb off for rebuild and it had rust in fuel bowl and other crap. Rebuilt best as I could and adjusted.

Idles well and runs well until about half throttle. Begins to bog down almost like its flooding. Recovers after a minute.

I have replaced the following:
Main fuel tank, sending unit, and lines.
Inline filters prepump and at carb
Mechanical fuel pump
Plugs, cap, and rotor. (still has points).

Questions:
1. Does this sound like fuel related or electrical/ignition?
2. Replace carb with new one?
3. If so, go to 2B conversion?
4. Install Pertronix Ignitor?
5. Replace plug wires and coil?

Or all the above??? Eventually I'd like to do all the above, but want to get it drivable and enjoy it for a bit.

Thanks for the info and sorry for the long post.

Any black smoke emitting from the tailpipe when it bogs down? Sounds like a fuel condition, possibly float adjustment or accelerator pump on carb. Black (not white or blue) smoke would indicate an over abundance of fuel that can cause a hesitation, but if there is no smoke then it might be a lean condition that means lack of fuel. Either symptom needs to be adjusted differently. I would mess with the carb and see if there is any difference in how it runs, then maybe invest in a new carb first to see if the problem totally goes away. Also do you have a vacuum gauge? A vacuum leak could cause some odd acceleration behavior as well.

No black smoke, or any smoke. Vacuum hoses are also on the list to replace. Pretty much all rubber pieces are in need of replacement. I'll test for vacuum leaks/issues. Cheers
