Blowin' in the wind...

Doc Here

If it's not Fuel infected<--- misspell, but I like it so it stays..) and Carbed....and blowin Black Smoke and runs like Crap in a can...Follow his procedure and see where you come out.

I think I answered your PM on this with a request for more info...

Doc Here

The most simple way to Adjust the Mixture Screws on an Q~Jet (And Many others)

Is Carefully turn them all the way in.
(don't jam them or they'll leak)

Then back them out 6 half turns.
(3 total turns)
Then Start The engine.

Adjust for Absolute Highest Idle.
(Turn slowly and listen Carefully This may take a lot of time going from left to right and back again)

You Want the point at which Highest Idle Begins, With No Stumble or Miss ... Smothe high idle.

Check the exhaust for raw fuel smell as you adjust You want the minimum Smell From there.
(You may not be able to get rid of it all with just the Idle Screws, so just the minimum will serve)

After You Think you have it right, put a Vacuum Gauge on any Non~metered Vacuum Port or manifold and set for highest Vacuum At Idle about 17 to 20 Hg Depending on your engine, and on Rev, should Drop to about 5 To 10 Hg and return.
(You Should be on or at that spot with the higest idle setting anyway.)

That Should Do it!


You can only tie the
record for flying low.
What is that mountain goat
doing way up here in the clouds?
