I have a OS-46sf that I have been flying all summer. Start it, fly it. Don't have to mess with it. Today it started acting up. I had three dead sticks. I haven't had 3 all summer. Seems to be running hot. I even ran it rich and it sill dead sticked. Using Omega 15%. Any suggestions as to what to look for. Needle valve was very hard to turn. I removed it and use the elect. starter to flush out the carb and needle valve.

how many flight on the plug?if running hot it means you are running lean so there is air getting in somehere,check fuel line,fuel filter ,klunk,back plate screws oring under the carb even muffler pressure line.something has changed somewhere

Pulled the fuel tank and it appears to be OK, but I replaced the lines anyways.
