More carb troubles, engine won't return to idle revs
Matt_Harrington:
Bill, I'm currently rebuilding a spare set of carbs and I'm reading this with interest (sorry I can help yet!) and I will be interested to see what the outcome is.

Ha! I have to admit that I could have chosen from 2 sets of spare carbs to rebuild and I chose the wrong set! Parts missing ,damaged or just wrong - still I'm almost there but I have to admit they are quite complicated compared to other carbs I have restored!

Sesman:
Hey Scottish nadger. When you cleaned the carbs did you remove the air screws and float bowls? I’m sure you know, but it pays dividends to understand the three orifices in the pilot jet pathway. Eg carb inlet, air screw and drilling in the main Venturi on the engine side of the slide. By judicious use of your fingers it’s possible to block of the routes in sequence and thus force carb cleaner and high pressure air through the pathways. Have you tried that with the carbs off the bike?

Er badger, not nadger🤔
