[6pack] A question for carburetor gurus

[Brian@asmoothmove.biz]

Thank you, Vance. I will check the vent valve that you mention. I actually
didn't know there was one. The needle and seat are OK - maybe the main jet
and needle are worn out.

	Brian:

	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.

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,
