I adjusted the float when I was putting everything back together, and it should be correct if not a little rich.

Bagus, I do not have the Power brake booster, and the Venuris are nice and clean. When I get home I will Cap off all the lines except the Distributor and see what happens.

I'm having trouble assessing the timing and adjusting the idle/air mixture, because I can never get the jeep running long enough and consistently enough to make adjustments or check the timing.

I'm sure there is something I am missing (Weber 38 or MC2100) that will make my life easier. Thanks for your help and any future suggestions are appreciated.

I'm about at the end of my rope and I really need an Ah-ha moment so any help would be greatly appreciated.
What happens when you give it a little gas? Does it die or rev nicely? Do you have a choke? Do you smell gas while the engine is idling? I'm just wondering if maybe its getting too much fuel. Just a thought. Rob

The engine revs nicely. I have an electric choke that I've toyed with but to no avail.

Would my idle be down around 2/300 if I was getting to much fuel? There is a smell of gas while idling.

You could be flooding it a little. I would recheck you idle mixture and your choke setup. I don't have your carb so I can't give you exact directions however, on my carb, I turn the idle mixture screw all the way in and then back it out 2-1/2 turns for a starting point of adjustment. If you smell fuel like you say then I bet you have it too rich. This would make it idle rough because you are not getting enough air mixed with the fuel until you step on the gas which opens the butterfly up. I would also go through that choke again. Rob

Have you cleaned out the Venturi cluster brass tubes? If you had sediment in your float bowl its in other places inside the carb as well
