carb question

[Lord Grizzlon]

i have my bike in the shop, and they dont kno why the carbs are flooding.petcocks and diaphram have been rebuilt, carbs cleaned, floats adjusted, float needles not sticking. Im thinkin about they have petcocks on prime and not on.

If all of that has been done and you are still flooding.... then even though the floats aren't sticking.... for some reason the needle valve is not sealing like it should..... such as a groove or nick worn in the needle point or seat, or the o-ring or gasket for the seat is worn and leaking. If the needle and seat are doing their job... even with a wide open petcock... it should not flood. Unless the bike is being trailered and the floats are bouncing.

Have a real good look at the fuel line routing diagram. Also, test the petcocks to verify their operation i.e. confirm which spigot flows fuel for which tap position. IIRC, it is possible to reassemble the petcocks 'wrong' and end up with fuel flowing when you think it should not be. Finally, use a vacuum pump (or short piece of hose and your mouth) to operate the diaphragm in the octopus to verify how and when fuel flows through and how and when it does not.

Then, like Jeff said, there's probably still a problem with the float valve(s), either wear or dirt. If you have verified that the floats do in fact still float, and they're not sticking, the float valve will stop the flow.

Might be time to bring it home and 'do it right' yourself??
