the motor is idling on five cylinders... (IMG:http://www.914world.com/bbs2/html/emoticons/mad.gif)

Good off idle. comes up to 7300rpms fast.

The dead hole is driver side center ( #5? )

I squirt cleaner down the barrel at idle and it picks up.
So it gets spark and will burn. Not getting any fuel at idle.

Cleaned all the idle jets.

What's next?
Help me get happier.

Before you pull the carb off, disassemble it and clean it try one more attempt to clean #5s idle circuit.

The carburator (I'll assume 40IDA 3C) has a air intake on each idle circuit thats part of the top cover. Manuals reference it as as bush or air venturi.

Some carb cleaner sprayed into the idle jet hole will validate weather this is open. Don't try to clean this port with a probe as you will very likely disturb dirt and drive it into the circuit.

- Pull the air cleaner and remove the jet holder and idle jet.
- Get your favorite carb cleaner with an extension tube so you can concentrate/extend the spray easily into the idle jet hole in the carb body.
- Place a shop rag on top of each idle circuit you are cleaning, directly over this air port. Fluid will squirt out of the hole if it's clear.
- Spray carb cleaner into the hole. You might also hold a small shop rag under each circuit to catch excess spray.

If the carb is really dirty and you have an idle circuit stopped up it's probably time to clean them both.

Another indicator of contamination in the carb can be found at the bottom of the float bowls. Pull the drain pugs and carfully catch the gas. Inspect it for contamination. If you see evidence of dirt here you can be pretty sure it's trying to getting to the idle circuit as well.

Good luck!
