Hi. Is it a CT model ? A few of us with these engines have had issues with the terrible plastic exhaust bore sleeve ring behind the prop. Wee white plastic ring. It comes lose and causes the prop to vent. Really good chance it’s that. I had to stick mine in place. Doing exactly what you are finding.
