More airhead/BING woes....

Got fire in the left cylinder - checked plug, wire, plug end caps, and coils. (I switched wires and coil to "bad side" and no change.

Cleaned both carbs at same time in shop hot tank that's like a big jewelry cleaner.

Now, she starts quick as hell on the right cylinder but left cylinder isn't doing anything UNTIL I squirt a little ether in the left carb and she'll start running for 2 seconds until ether is gone. OR if I partly cover the intake side of left carb she'll rev up and fire until I take my hand away and she'll backfire then go down again. So, it certainly seems like I have a fuel issue on the left side. I took the left carb off again and cleaned up the jets. The float is working - when bowl is off and float is dropped gas comes pouring out. When I push float up to level of carb base it stops. It seems as though fuel is not getting from bowl to combustion chamber.

Any thoughts?

Hmmmm...So must be carb-side of idle jet. (blocked circuit) I took the jet out and small wire went right through it.

Use the small wire to route the bore of the carb body that is fed by the idle jet. I think this one has a bend in it so you have to find the bottom from the jet side and then the bottom from the carb throat side. A deposit loves to grow right at the intersection.

Make sure the idle jet and pilot jet o-rings aren't damaged. The sharp edges of the brass easily slices the o-rings, and then the slit hides where it's not visible. You'd think it wouldn't make any difference if you can't see it, but it does.

I smooth those sharp edges which prevents that happening.

If an o-ring is getting cut I thought that would allow too much fuel into the circuit. I don't seem to be getting any.

O-rings and passage ways...slow jet(pilot/idle), mixture screw...
Whilst you're checking, flushing, blowing air thru, also check the starter jet in the corner of the float bowl.
