So $7.00 was billed as labor. The mechanic probably saw less than $2.00 of it.

Hello Can you identify the applications for this TWOLITE?

I cant imagine the oil getting hot enough to actually break down modern oils.

I think the carburetor shop has a 6 month wait time for kits. Each one is custom made? Is this correct?

Your engine is a Standard engine. Fan and pulleys are truck only. Engine looks 1928 due to not having the boss for a mechanical fuel pump.

How much did it go for?

.

I have a 1930 Buick distributor for sale.

Is this still available?

Looks Buick in design. Mid 1920s. Buick mounts via a clamp system.

I would suspect a leaky needle and seat in the carburetor. You might start trying to isolate the culprit by running the engine then shutting it off. Then disconnect the vacuum line at the intake manifold and disconnect the fuel line to the carburetor to see if unwanted flow is occurring. Monitor this for a period after shutoff. I cannot see how the heat riser tube could be a factor in what you are describing.

In similar instances I have put the car on jack stands with suspension relaxed, put as much pressure as possible with a grease gun and then heat with a torch. I would avoid overheating the arm as that's not a throw away part. If that doesn't work remove cap and dig out hardened grease. I am assuming that you have removed the zerk and dug out as much old grease as possible.

Your clutch and pressure plate actually look pretty good. I unable to locate replacement parts, you may have to have your rebuilt.
