Need some help - Port motor not running
Port motor is giving me trouble. It will fire off occasionally, run like complete **** and shut off (if I can even get it to fire). I am an old school setup - thunderbolt IV, MSD Blaster ignition coil, single Holley carb setup.
So far I have swapped my MSD blaster, thunderbolt ignition, and carb from one motor to the other with no luck.
Unbolted the MSD rev control box with no luck.
I cleaned the distributor cap the other day - carbs are full and pump gas whe I pump the throttle. No water in the oil or cylinders - I've pulled all plugs and found nothing unusual.
Could I have a ground problem? Problem in my ignition switch(which is a little finneccky)? I do believe one battery to be bad, but I'm using it on ALL battery position to overcome that concern......
Motors only have about 20 hours on them and have run fine up until now......
Thanks for any suggestions.

Saw you cleaned the dist cap. . If you got some carbon tracking inside the dist cap, it can't be fixed. You'll have to replace the cap. Try swapping dist caps.

I have to fix the hatch reservoir first so I can get the hatch up - always something.
