My 1968 Valiant has a 1973 slant 6 transplanted into it. When they did the swap, they kept the 1973 single barrel carb with has the vented bowl. They left the bowl vent on the carb open to the atmosphere which meant the float bowl dried out when the car sat and could likely be dangerous with gas vapors right on top of the engine.
I tried capping the bowl vent but when I did the carb leaked gas when the engine was shut off, which is never did before. I assume this was due to unvented pressure building up.
What is my best option? Route the vent away from the engine? Get a charcoal canister from a junkyard? Swap back to an older carb?
If I keep the car, I have a Super Six setup to install which will have the same issue.
