Hi Folks,

Can't start the bike after a winter of storage and finally discovered gas is not flowing past the petcock to the carb.  Not on any setting, including prime.  A complete disassembly of the petcock seams to show nothing abnormal - the diaphragm is intact, o-rings in place, nothing plugged up.  The screen filter looks good.  Just to prove gas is getting through the filter, I first removed only the back plate (that the diaphragm attaches to) of the petcock and turned the tank over - gas puored out.  It stops flowing when the diaphragm and plate is reattached.  I thought maybe the plastic cylinder valve wasn't turning in sync with the external indicator, but it looks oriented correctly when I reassembled - still no flow.  I did notice that there is a wide and narrow part to the slot where the external switch mates to the plastic internal cylinder.  So anybody have an idea what's going on or what I should try?  I hate to buy a new assembly if this one can be fixed.

Sorry for the long explanation and thanks for any suggestions.

I converted my petcock to fully manual as described here:

This procedure make the bike more reliable because you won't have diaphragm failure miles from home, and should eliminate your gas flow problem.  Don't forget to replace the oval rubber 'o' ring between the tank and petcock assembly.  Don't use silicone sealer instead...every type of Permatex sealer tells you it will not withstand gasoline immersion.  I bought 5 of these oval 'o' rings here:
