Leaky Carb out Drain Tube

[MadMAx13]

Hi Guys,

I have a 1978 GS 750 with 33k on it. I recently pulled it out of storage outside from a northwest winter. I started it up which started rough but the drain tubes on the carbs are leaking gas periodically, not out of any specific one. The weird thing is that the bike runs very well for supposedly being flooded. It will idle well for a while then change rpms stay there for a while then eventualy quit running. Does anybody have any ideas? and could it only be in the carbs? Thanks for the help (summer is almost here help)8-[

Take off your float bowls and clean the float needle and seat. You realy should take them off and clean them. These carbs don't sit very well and need a good cleaning if they do.

Agreed, but use this clean-up guide - http://www.thegsresources.com/files/vm_carb_rebuild.pdf - it's specific to the VM carbs that are on the '78 750.
