Magnum Engine question
Just picked up a new plane with a preinstalled NEW Magnum .52 glow.
Owner claimed the engine had not been run or the plane been flown (Phoenix funstar)
I finished the build of the plane, installed the fuel tank and set out to the front yard for some engine break in. I installed an OS #8 glow plug, fueled up, applied the glow plug starter and electric starter, the motor will not spin. Acts like a hydro lock. Removed the glow plug no fuel in the engine. Re applied the glow plug. Acts like a hydro lock, will not spin. Removed the glow plug and it spins just fine.
I had a burned out Evolution plug from my Alpha 40 trainer, just for kicks, I dropped it in the engine, the engine spins free. Put the OS plug back in, it acts like a hydro lock when I apply the starter.
I am new to the hobby, flow an alpha 40, built a phoenix dolphin with an OS .55 never an issue. New to Magnums. Is there a recommended plug to use. The website for the magnum engine says a hot glow plug.
