so you have to get that circuit clean without breaking off a wire in the passage way... if you do the carb is toast ! .... i straightened out a small spring and used it, it flexed around the corner well enough to get a large chunk of crap out of the left carb ....so I THOUGHT i had got the offending junk out... alas it wasn't ALL of it.......

Yup, see deposits on bottom of float-bowls?


That's also inside internal passages and jets as well, clogging them up. Here's secret hidden passages in carb-body that needs to be scrubbed out with brushes and PEA-based fuel-system cleaner.

That's why ultrasonic soak and micro soda-blasting is needed. Modern carb-cleaner sprays can't dissolve dried petrol deposits any more due to removal of chlorinated compounds. Mechanical agitation, scrubbing and blasting is required.
