Been thinking about the fuel flow problem I have been experiencing again
with Patience. I shortened the length of the top fuel hose on the right
side as Andy noticed it was a bit too long and was pinching. After
shortening the length and turning on the petcock, no fuel would flow
out. If I wiggled the hose, a bit would trickle out but would stop.
The fuel lines were full below the splitter, but I would think the fuel
would have filled up above it once the fuel was turned on. If I
remember correctly, I think the left petcock was opened as well and fuel
was in the top of the left line as well. Can an air bubble cause this?
Strange thing was my 1st ride on Patience felt as if she was lacking
punch, like she was running lean, too much air not enough fuel. When I
stopped and put her on the sidestand, I noticed there was no fuel in the
right side fuel line going to the carb. When I stood her up, the fuel
then went into that right side carb. I don't recall this ever happening
before. Patience is at the photographer's shop now, we are taking a
family pic with her. I plan to readjust the carbs after the ride home
as the idle dropped when she was warmed up after the highway run and
pulling the clutch in when stopped dropped the idle down to a stall
situation, so I want to up the idle some and make sure the mixture is
on. But the fuel flow thing has got we wondering if the carbs aren't
set right but the fuel isn't flowing. Andy had the carbs apart and
cleaned everything, so those vent holes should be clear.

Ideas anyone?
