36 years old 026. Couples of years back replaced fuel and input lines and overhauled carb. Run well until 2 weeks ago, when it started leanig and surging after a rew seconds in the cut. Replaced clutch side seal. Tried 2 days ago, it start, runs and cuts very well for half an hour, then it changes tone, sounding lean and dies. Let it cool 1 hour, start, cuts well again for a while, then when hot leans and dies. I checked the carb and the diafragm looks fine, rechecked vacuum and seems to be holding. Any suggestion as to what can be causing this?
