1969 Bus - Loss Of Power
Hi list,
69 Bus, 1600 dp, Solex 34 PICT 3, vac advance dizzy.
It's been raining a lot. Yesterday, the bus felt like it had really lost power. Acceleration is about half of what it used to be.
Check plugs; snug. What's next? Could the rain be a factor? It has never done this before.
Suggestions?

Hi James, I'm a new guy doin' a neck out stab fer ya!!
Did this lack of poop happen from one day to next?
Daily driver or a parked bus?
Throttle cable and carb linkage all OK?
Is a brake/e-brake draggin' or hot?
Distributor cap dry & clean inside & out? Rotor end shiny, not pitted? 4 x cap contacts nice-n-clean or worn? Cap seated correctly? Coil wire firmly in at both ends? Spades on coil clean/shiny?
Distributor locked firmly in place?
Have you checked timing?
Have you checked the vacuum lines for leaks/cracks?
hmmmmm . . . . . that's where I'd start!!

"How do I find vac. leaks?"
Listen for hissing sounds while it's running or you can spray some carb cleaner around the engine until and if you find a spot that changes the way it runs.

Loss of power must be investigated seriously. Check valve adjustments cold. Compression test next. If no gauge, pull #15 coil and crank engine to listen for an uptick sound at one cylinder. If it is steady, then we can move forward.

Thanks for the suggestions. After some head scratching, i think I solved it.
Removed wires one by one from the dizzy to see if there was a misfire. Removed #2 and nada. Checked the plug. It was wet. Oh no!
Changed the plug and checked the ignition wire. Some of the rubber had worn away.
So I think #2 wasn't firing because all the rain and humidity had caused that bad ignition wire to crap out.
Swapped out the wire, and viola!
Thanks again.
