What's the difference?

Brings back memories, and gets a smile for the hundreds of times it happened.

My wife says that vacuum is what I should be doing instead of reading posts.......but I can't learn anything cleaning.

Went with AlanB's suggestion and disconnected vacuum line...didn't change a thing.

Fred- the problem happened during my ownership, which prompted all of my attempts to correct it. So far I've:
-Replaced the spark plugs
-Trimmed the ends of the plug wires
-Checked for vacuum leaks at the manifolds. Didn't find any, but I wrapped the carb boots anyway and installed gaskets between them and the head.
-Replaced the vacuum caps
-Took the carbs off. Cleaned 'em. Set the floats to 23mm from 27mm. Reinstalled.
-Took carbs off again. Replaced all 4 o-rings for the float needle seat assemblies...no more leaking from #4. Removed all the jets again including the emulsion tubes this time. Cleaned 'em all again. Re checked float height again. Bench tested for leaks. Flipped 'em right side up before putting the bowls back on to make sure floats all hung at same level. Bench synched. Reinstalled. planedick and TheWiz came over and used planedick's carb sticks to sync.
-Pulled PUC assembly off to access and lube centrifugal assembly. Replaced PUC wires because PO wiring of same repair was brittle and cracked. Discovered flat spots in rotation of advance plate.
-Did resistance check of ballast resistor...1.5 ohms exactly.
-Did resistance check at TCI 4 prong plug...720 ohms both tests.
-Did voltage check to TCI...should be 12vdc, measured 11.37vdc.

I have the Jardine spaghetti pipes w/o the crossover, K&N air filter in the stock airbox. Denso W20EX-U plugs. I haven't checked the resistance across the primary coil windings yet...don't know why. Becoming more depressed daily. I used to really enjoy my 400miles/week. Hoping I can get back to that point...soon.

Hey Mike,

Just to understand the main problem you have, it is on accelaration? When you give the right side a good twist you get a hesitation before it picks up?

Does it run good after the hiccup?

No kinked fuel lines?
Proper jet sizes for Jardines?

Gonna have to pull the carbs again to check jet sizes...shoulda done it last time.
