Have never had to fix or replace an electric choke/element. Just removed this carb and cleaned inlets and needle/seat aspects because it would not take in fuel, even with 9 psi from pump (ethanol caused surface build-up on needle valves so they stuck) - re-installed and it fired up and ran great.

BUT, once warmed up it was very rich at idle and stalled. Took a look at the electric choke - it was smoking from under the adjustment cap and the choke baffle was mostly closed. Could the heated element in there have cooked and, if so, why? Would that be common?

With key on, still have 12v to the choke and across the two terminals. Nothing in the wiring was changed during the remove/re-install. Is an element burnout likely? Can a person replace whatever burned, or is a new unit needed?

Thanks for any insight.
