The idle circuit meters fuel at low speeds only. when you raise the rpm, the main curcuit takes over.

This new, reformulated gas gums up very quickly. it sounds to me that you have some clogged

idle circuits. I had the same problem on my '82. Since the carb is now 20 years old, it would be a good

idea to clean it up. Take it completely apart and soak it in some Berryman Chem-dip. It's about

$13 but well worth it.

thats what I did ^



I remember marking every little piece to make sure where they all went but when I took the jets out I just threw them in the bucket. https://www.nopistons.com/forums/pub...IR#>/blush.png (I was 16 and didn't know that the primary and secondaries were different) So I put it all back together and it didn't run "just right" so I said **** it and took it down to a shop and they said "We can't figure out whats wrong with it, it's almost like the jets are mismatched" https://www.nopistons.com/forums/pub...DIR#>/ohmy.png doh. So I drove it home and swaped jets then she purred like a kitten https://www.nopistons.com/forums/pub...DIR#>/cool.png

yeah i think i'm either gonna pull the top off of carb #2 or rebuild the original

Yup, I found gum in my secondary apply circuit. The one that applies vacuum to the

secondary diaphragm.



What I did was, make a diagram of the top of the carb where each air bleed is by number,

then disassembled, dumped out the rust and scale, put everything into the dip (minus the

electrical and rubber parts) for 1/2 hour then rinsed with water. Blow dry w/compressed

air. Then before assembly, I shoot carb cleaner through every port, hole, orifice, and air

bleed. BE CAREFUL!! Some of the holes will shoot back!!! PTUEY! https://www.nopistons.com/forums/pub...IR#>/blink.png

Then I reassemble. Check your float drop and rise against the manual with the gasket

installed.

Inspect everything as it comes apart, Take pictures if you have a digital camera and let us

know how it goes. https://www.nopistons.com/forums/pub...DIR#>/cool.png

I do a lot of digital photo taking before and as I pull **** apart. Makes reassembly soooo much easier. https://www.nopistons.com/forums/pub...IR#>/smile.png

oops, well you guys get pics of it going back together!



mike

Think its ready to run properly yet?
