View Full Version : IT'S ALIVE!!! *cough* *cough* Carb tuning question now
Ok, so I put on the new starter, new starter solenoid and the freshly rebuilt carb (stock 2150). I fixed the neutral safey switch problem for now (permanent fix to come...) and got it to turn over. It fired right up with no problem. The new starter parts worked great.
The only problem I have now is that it's idling way rich. It smoked me out of the garage in less than a minute so I shut it off, turned on the fan and waited for half an hour for the air to clear.
I'm going to start searching (on the tech pages here first) on how to tune my rebuilt carb. Does anyone here have suggestions or possibly a link to a page or two on "carb tuning 101"?

Okay....here you go.
Step one. Adjust the idle where it keeps running (that is if it dying.)
Step two. Adjust one of the mixture needles till it stumples. Not dies but the idle may come down and it will stumle.
Step three do the next one the same way.
Then Turn one needle out until you get the best possible idle.
Do the next one the same.
Adjust the idle down or up accordingly to what it is doing. At this point if it is too high, adjust it down a little.
Then trim back one needle, making sure you are not loosing/or hearing any variance in the idle quality.
Then do the other the same way.
After that is accomplished. (best Lean mixture) adjust idle again.
Since you timing is not set you may or will have to play with that as well.
Anyway....we will play with it next weekend :D
I forget the name of the screw in nedles underneath the fuel bowl but I turned them in all the way then 1.5 turns out each. The one on the driver's side is a little difficult to get to without pullin off half the vaccuum lines and the distributor cap...
It's still not tuned well but at least the smoke is a lot clearer and it doesn't smell so bad. It stays running, but "surges" and stumbles a little. I'm sure the timing is off at least a little. I'll take it out on Friday, tune it so it is drivable and run it down the block to the City Garage to see if they can tune it to pass emissions.
