Interesting model and a new one for me, thanks for explaining it in the video  :)

Title: Early Ervin Hit and Miss Engine
Post by: crazydoug on October 19, 2020, 07:15:43 am

This was my first purchase at the Coolspring engine show.  Ervin is one of the earliest of the model hit and miss engines.  I bought it in "as is" untested contested condition, but had it running that evening.  It only took a good cleaning of the points and figuring out that the engine had been set up to run as a vapor engine.  Although it runs fine as a vapor engine, it will only run for 15 to 20 minutes, until the fuel level in the tank drops a third of an inch or so.  I may convert this to a system with a pick-up tube and check valve, so that it runs on liquid fuel and will run until the tank is empty.
