Heat Riser Operation - Testing

[@MarksGarageChannel]

Thanks for posting this. I have to test the one on my 47 GMC while I have access to the engine.

I have read that this happens to the Chrysler slant six engines and there was a maintenance lube to apply at least once a year to loosen deposits and free it up while mounted. I thought it odd at the time that there was a reference for a GM product and also an updated Mopar product that could be purchased from Amazon.
