	In theory it should not happen, but I must admit the same thing happens to
me. It appears that the rear carb is very prone to heat soak, and the fuel
expands and pushes out of the jet.
	You should check to make sure that your vent valve is correctly adjusted, and
that your needle valve is not leaking. Other than that, I would say a heat
shield is your best bet. But perhaps others have had success with this
particular issue.
	I would not expect the carbon canister to affect the problem.

Subject: [6pack] A question for carburetor gurus

Here's a question for any Zenith-Stromberg gurus out there. While diagnosing
an acceleration stumble problem, I noticed my rear carb has gasoline
dripping from around/above the piston area. It actually looks like it's
coming from the vapor return hose as the line is wet on the inside as well.
The front carb is dry. The vapor return hose attached to the front carb and
then end up at a charcoal canister. Is this normal behavior? FYI. I am
actually using a canister out of a 1990's GM car as the TR replacement was
way too expensive.

Thanks for the help,
