Hi All,
Bert, the yellowish tinge is where the kerosene had found it's way into one of the float bowls. The powder is an oxide but I wonder whether it has leached one of the components out of the carb body alloy or the zinc out of the brass floats/jets etc. You would think there would be obvious signs of metal loss but everything seems reasonable.
Mike , it will be going in the evaporust, nothing to lose, except big chunks of alloy
. Certain alloys will crystallize with age and become brittle, like the oil pump outlet unions. Might be late next week before I can try it.
Brian.
