I had a problem where the engine would die when set at half-choke and the throttle was advanced. (Could be advanced a little without dying but not full.) At no choke the engine would not run at all. I tried adjusting the jets to no avail- I purchased a Zama rebuild kit. When installing, the carb looked extremely clean and no parts appeared damaged or worn. I did not soak the carb at all, maybe a bad idea. On reassembly the engine runs better but not perfectly. It now runs fairly fast at no choke, but still runs better at half. It wants to go to full throttle at half choke but then seems to run unevenly and slower. Oddly, when then moved to no choke the rpms increase to almost full throttle but then go back down again. Three options to do next: (1) Take the carb off again, re-disassemble and soak. (2) Assume the tank strainer has a problem (what to do if it's that?) (likelihood?) (3) Assume the gas is bad and replace. (Gas is LT 6mo old.) What would you do *first*? Thanks for help! Frank
