Thermoquad "super quad" questions!

The vacuum choke pull off and the rod is missing.
All the electric choke parts are missing.
The choke ate is missing and may cause hard starts and driving when cold.
(As in cold engine not air temp.)
No need to modify it, use as is.
The bowl vent tune gets connected to the vapor canister. It helps vent the carb for driving and starting as well as emmisions when driving or sitting.
If you do not connect it to a vapor canister, leave it as is. So not cap it. A filter or breather on it is not needed.
