<VV> Help - Engine runs worse than before!

[Bill H.]

Harry, scratch the coil thing.  I forget that you have to switch the selector to 1K.  I got a reasonable reading.

When I sprayed carb cleaner against the choke shaft on the left carb, the enging sped up and smoothed out.

Could that be a worn choke shaft?  You can see a small gap where the shaft meets the carb body.

Thanks...Bill
