If this guy hasn’t got the information by Saturday I’ll run out there and take a look complete…. Bob 1 Quote Link to comment Share on other sites More sharing options...
Popular Post HarryS Posted December 13, 2023 Popular Post Share Posted December 13, 2023 I found an old B Model operation manual for gas powered trucks. It calls for 10* BTC with 91 octane gas. That was when gas was gas with lead and without alcohol. The closest thing in today's gas would be non ethanol with the same octane rating if you can find it. Probably have to experiment from that point. 3 Quote Link to comment Share on other sites More sharing options...

mattb73lt Posted December 13, 2023 Share Posted December 13, 2023 I believe they’ve found the newer gas doesn’t cause the valve and seat wear they thought it would. I’ve run older engines and haven’t had issues due to it. The engines I have had rebuilt, I did specify new valves with hardened seats. Mostly because they were worn and I wanted them to last. That’s been several Model T’s, flathead V8 and the ‘41 Cadillac I run. I’ve driven all extensively. There have been recommendations about adding Marvel Mystery Oil or 2 stroke oil when you fill up your tank I’ve read about. 2 Quote Link to comment Share on other sites More sharing options...
