Adding Evaporative Controls to 273 2B

Thank you for the suggestions, they agree well my thoughts.

I added the thick spacer under the carb with little improvement. When the car is warmed up, I do notice a fluctuation in the idle at random 2 second intervals, it may be an internal fuel drip. It could be porosity in the bowl, so not much of a way to solve that. The vacuum gauge does not tick, but I may check valve lash today since it happens only when hot.

I do not seem to get fuel in the oil, so it might happen slowly enough it evaporates before it spills to the cylinders. I have checked the float level on and off the car it is correct. I encountered a leak in the new fiber entry seat washer, so went to the aluminum one then had to set the float using on the car procedure. I was uncertain, so I checked again, inverted off the car and it was spot on. I use a float T-square rule to be exact.

I think mounting the canister near the horns may keep it cooler. I will try that.
I may have to give up the added radiator overflow tank that resides there.
