Here's my ordeal. My Kadrons spit, spudders and bogs down when the accelerator is depressed. Idles good. Runs good when wide open. When bogging down I can feather the throttle and it picks up and goes. It's burning rich according to the black plugs. No backfiring. I'm running electronic ignition, 1915cc, 110 cam, stock heads and Tri Mill header. Carbs are rebuilt by AJ. I ran it all year last year like this. It's time to fix it!

1) Since your setup worked well in the past, it
may be safe to assume that your fuel is suspect.
I like to "winterize" all of my engines with
fuel additive in a filled fuel tank. I then disconnect
the fuel line and run the engine until it dies.
Works every time!
2) If/ when this is not done, the real headaches
begin. I have had to soak carbs over and over
and sometimes never get success.
3) If none of this applies to your setup, then I
would try new seals at the base of your carbs
and where the intakes seal to the heads. Check
for intake and carb leaks with small amounts of propane
on an idling engine.

I checked for leaks around gaskets...none found. New dizzy. Plugs are not fouled. I will check plug wires for bad connections today.

To me the 1st sign of bad rings is no power during a low rpm grunt. And rich fuel is hard to lite off at 60 psi or lower. Therefore unburnt fuel loads up the plugs and the cycle continues. Put your finger in the exaust tip and taste it. lol. Lick your finger and touch each exaust by the head after running for 10 secs and see which one is cold. If compression builds about 20 psi after squirting oil thru the sp. plug hole for a minute then rings and/or cylinders are bad.

It taste so Sweeeeet...lol
Motor only has about 400 miles on it. Built by Bruno. He's our VW man up here in east Tennessee. I did break out my vacuum Gage today and checked vacuum. It was low for my 034 distributor. I up it by adding the other Kaddie to it. Now I need to reset timing. But I might still do a compression check on it. Never can tell..........

Is this a points dist? If you can find a dwell meter fool with the gap until you get 48 to 52 degrees dwell. My smaller AC'S never seemed to care but my 2180 did exactly this unless dwell was right on 50

I had a rip in an intake boot where the clap goes that did that ..I didn't see it because it was in between the shroud and the intake on the back side..finally found it when I was spraying carb cleaner on them..just an easy check to do before you tear it apart..lol

I see it from the pictures. Moving the setting outward reduces the amount of fuel that the accelerator pump pumps.
