Newagerocker (cool avatar), I have the jets on the left of your pic, 2 holes on 4 sides. The old 27.5 and the new 30 are the same in appearance. I miked them and the length is the same.
Yanked the carbs again, checked the jet sizes to make sure and they are A-OK, put in the 142.5 main. On paper it all seems to be good, it's almost rocket science, but it is still a carb.
Been fooling with the Pilot screw and no change. Warm it up. Been fooling with the outside Idle speed screw and no change. Kick it, starts right up, a few seconds later it coughs and stops.
Rerouted the fuel lines. Very Big question however. The fuel lines on the way from the petcock dip down, then go up (but not higher than the petcock) and back down again to the carbs. I'm not a plumber but is that an issue for fuel to flow to it's destination point?
So now, after it warms up. Kick start it on first kick, runs for about 3-4 seconds and stops. Give it some throttle and it stops right away. And on top of that some new squeaking sound is coming out of somewhere, not a carb pop, just a squeak somewhere, whatever.
I'm running out of gas on this one.
What ever happened to the technology of the old S&S Super B where it worked like charm on anything you put it on?
Anyway, I'm thinking to pull the carbs, move the needle to rich up the mail jet a bit and try again. What do you guys think?
