...sup all, changed from 110 to 120 jets and now it won't start...rolls over a little, but nothing else.  Am I missing something?  Running pods and pipes...started fine with 110s...

what do you mean by "rolls over"

[scondon]

Petcock "on" and fuel in bowls?  Run switch off?

Seriously, can't think of any reason a jet change would stop your bike from starting.

...yes to all of the above...when I said "rolls over" I just meant it pops like it wants to start, but won't.  Got spark...I'll sleep on it...maybe something will come to me.  Just thought maybe I needed to do something else if I changed jets...

[Buffo]

did you bugger the float hights when you did the jets?

I dont remember if the mains have o-rings in them or not (between the main and the stem)...if they do, did you install them?

And I take it you tried the drain screw on EACH carb to make sure they all had fuel.

...turned the drain screws, and got fuel.  The carbs are probably dirty.  This is a set of carbs I brought back from the dead, so I'm sure there is lurking garbage in them.  I've got a set of carbs I know is good...I'll put those on this weekend and see what happens.  Oh the woo's of carb troubles!!!!
