Hi guys,
I need some advice. I recently swapped out a badly scored 1996 chinese power torque for an earlier aussie power torque in great condition. I swapped the starter from the chinese engine and the coil and set the air gap to 0.25mm. I serviced the carby and fitted the red deluxe cowling from the chinese engine. It starts with the slightest pull from cold and is one of the smoothest running power torques i've come across. I run it at or near full throttle however the muffler is getting so hot it is melting the cowling above. At the time i was using 98ron so i switched back to 91 but its still happening. I swapped to another 'good' muffler but its still happening. Have tried experimenting with oil/fuel ratios from 25:1 to 40:1 with no avail. It doesn't appear to be running lean, it runs and sounds great, i've rechecked the piston and it looks great, no scores just a nice film of oil. Any other ideas? Does the aussie engine run hotter?
Cheers,
Dan
