THUNDER TIGER 54 4 STROKE AERO IC GLOW ENGINE JUST HAD NEW BEARINGS FITTED AND COMPRESSION IS VERY GOOD. UNFORTUNATELY THE THREADS ON THE EXHAUST OUTLET ARE NOT VERY GOOD SO PREVIOS OWNER HAS EPOXIED AND DRILLED AND TAPPED THE HEAD WITH 3MM SCREWS TO SECURE THE EXHAUST IN A FIXED POSITION. A SERVICABLE ENGINE OTHERWISE NO LONGER MADE COMES WITH A GLOW PLUG.
