Emissions on my Slant
Currently, it looks like you are venting gas tank vapor to the engine compartment near the ignition. I expect this is not the original canister. The three port canister does not use a thermo switch (yellow) to ensure it only purges when warm. There should be a restrictor somewhere in the canister purge line to the base of the carb. Something to plug the line (like a one inch long piece of 5/16" rod) then drilled .030" or so should suffice to purge the canister and keep pellets out of the carb. The purging function is a vacuum leak. The bowl vent can be capped at the canister if you don't have a bowl vent port on the carb. If liquid fuel (not vapor) ever reaches the canister, it will solidify the carbon pellets and they will need to be replaced. It would need to be cut open to do that or just buy a new canister.
