Hey guys, so I've got my cruiser pretty well situated, I've replaced and fix tons of crap and lastly is the damn Webber carb. I've been putting it off til after Christmas. Now we've started dipping into below freezing Temps and my cruiser doesn't want to start. Here's what's going on. When I try to start it, it acts like the battery is dead, barely turns over and will not start. Today I was messing with it in the parking lot after work and I moved the distributer because it seemed like it was a timing issue, I turned the dizzy clockwise all the way and walla it fired right up! Awesome, until I attempted to move and then it just sputtered and died. I restarted it, changed the distributer back to where I had it and drove home. Here's my questions, how should my vacuum advance be ran? Is it possible that it's advancing my timing too much when trying to start it? As of now my vacuum advance runs from the diaphragm on dizzy straight to the Webber, the vacuum retard goes to? I honestly don't know where it runs. Who's a master at Webber jetting? I'm going to order a rebuild for it and a jet kit, it runs RICH!!! it's horrible, I can get it tuned to run good but it always sputters at a certain throttle position mainly when I'm lightly on the throttle just cruising. If i give it a fair amount of throttle it runs smooth and pulls good.

Sorry, but Webers are not really a good fit to the 2F.
Try for a Aisin from one of the vendors here.

Yeah I've been noticing that.
I have an Asian carb on my 2f, This is where my loyalty resides.
The (dead battery)start like conditions is in fact a result of excessive timeing.
there a couple of difrent Weber, and various ages, can help with the jetting with more info,
if you have some free time and a timing light try to set up idle with ~9* of base timing and use the idle mixture/idle speed screw to obtain idle peramiters
Best off throttle drivability results from a low throttle blade angle, maximizing the transition cuircits
Let us know how it goes,

I don't agree.
Im not a serious off roader so I can't address some things I've read about Webers cutting out at steep angles, but for normal back country touring it's not an issue.
But Webers are simply the most tune able carb made, if you can't get a 2f to run great with a Weber it's because you don't understand the carb and how to tune it. I've been tuning Webers for 30 years and have used them on all variety of engines. I know of several 2fs personally that run great on a Weber.
There is a wealth of information on setting up a base line for the Weber. Make sure there are no vacuum leaks, some adapters are not as good as others.
Remember the old saying, "90% of all carb problems are ignition related."
