great thanks?  Does anyone know of a guy that rebuilds honda carbs and can fix stripped float bowel holes that have had previous helicoils in them?

Those orings should come with any gasket kit you buy for these carbs.

If they're off the carbs, why not replace them?

Why bother if they still seal like mine after 40 years (even being mistreated)? Why d'you think I asked?

Right so. That's why I keep them wet during hibernation. Every 2 months I drain the carbs (the fuel can go right into the tank again). Then I turn the big idle adjustment screw out so that slides are as low as possible, crank the engine a couple of turns using the kickstarter, return the big idle screw to its former position. Crank again a few turns. Open the petcock to allow floatchambers to fill again. Shut off the petcock. That's it. No chance anything gets gummed up, no chance any rubbers dry out. Done so for decades. The only year I kept the carbs dry (experiment) I had to replace some main jet O-rings.

i think to bay some" aspen" gasoline..its used in fire trucks gas engines.(for pumps and generators.and militæry instalations(. im ex fire fighter).it holds for years but costs a lot..vill try to run the bike almost dry..fill 1-2 liters  aspen on..and run the engine so it are in the system..so then i can open the fuel once at month and fill the carbs..and dont have to drain it aut..i hope..make it all more easy..i have some problems have gum filling the carbs..klean them 3 years intivall..a bit to often..i find that  thik slime Blocks the jets..but no korosion or dirt..easy to klean..just blow vith air..damed #$%* fuel is kommed to europa
