Ok, thanks for the reply, I will test the solenoid and go from there. I would rather keep my engine as fuel efficient as possible with gas being as expensive as it is right now.

As far as the timing, I guess what concerns me the most is the fact that all my manuals stress that you have to disconnect those vacuum lines when doing the ignition timing. If the engine is not under that much load at idle and the vacuum advance is not even effected at that point, then what is the purpose of disconnecting them?

I have not messed with any of the carb screws. It was running OK, before I rebuilt the engine. When it is cold, (lower 40's) the engine will actually idle just fine for a minute or two until the choke opens up. I have only put about 150 miles on the rebuild (back and forth to work). I haven't calculated my mileage yet however I seem to be getting about the same as before I rebuilt the motor (19-20 mpg).

Like I said before, this idle thing is driving me nuts.
One thing to ponder, I noticed on 4crawlers website, he mentioned a "dash pot". I thought this was just an EFI thing until I was reading on pirate 4x4 that they also came on carbs in certain years. I havn't gone out and looked at mine since I read about it, however that may be something to look at too. 4crawlers website shows a picture of the EFI setup however I am wondering if the one on the carb looks the same. My manual doesn't mention a dashpot.
Here is the link, it may explain it a little better.
