:mrgreen: ok , this bike has been stored for at least 20 years . I took the twin carbs off cleaned them then had to solve electric problemb . topped off oil , started it up , took one way ride . on my short ride on the way back it started to cut out , like it was fuel related . Pushed it back home and discovered that i had way over filled the oil tank , oil was every where . So i drained oil from bottom of engine made sure of propper levels . NOW it starts up then runs for ten minutes then cuts out . when i had it running the rpms would not go much over 3000 unless i put choke on and advanced throttle . Oh yah and now there is oil/gas seeping from header pipe where the pipe attaches .
thats prety much it . eye have been bitten by the norton bug and wiil not be abel to get proper nights sleep till after a long ride on my 75,850 commando .please help and THANKS

Typical Amal carb "choke" (enricher) operation:

Pulling cable(s) FULLY TIGHT = choke OFF

Slacken cable(s) fully = choke ON.

Sounds like you are doing the opposite, it describes your problem.

Congrats on getting it running!

Not much farther to go till you are out and about with a normal return home ride.

Aside from really boiling out the Amals to clear the pilot jets completely, this is exactly what happened to Ole Rusty (1970 750 Fastback)!

Zinc oxide forms in the passages and bowl bottoms and is chemically and mechanical bound to the pot metal and no hydrocarbon solvent will touch it, only physical methods and/or mild SHORT few minutes acid bath boil like vinegar or phos acid.

The way I renew the passage without surgery:

get two 28 1/2 guage syringe/needle. Fill one with muratic acid and the other with baking soda/water mix. The needle, fluid pressure and a little twisting motion will clean em out quick - Sulfuric acid works too but will distroy carb if not careful but more caustic for hardcore cases. Saved many carbs that way although people look at me funny when I tell them what I did. :mrgreen:

I've had some awfully bad carbs, none have failed to revive to like-new with a proper dipping in Berryman's Chem Dip.

Nasty stuff, but it's the right tool for the job.

Clean your carbs first. The oil weeping issue my be a stuck rings since the bike has been sitting for so long. The oil seals on your guides might be shot too? Maybe do a compression test and see if that side is weak.
