Instead of rehashing it all over again here, I've included alink to another forum where i first posted my issue. Its a crappie website as i was using my side image unit when it first happened. https://www.crappie.com/crappie/mec...tic-2-stroke-oils-current-minor-engine-issue/ Ive installed a thermostat where there was none. New water pump. New temp sensor. Pulled head and inspected. Flushed with ac iid sssolution.
