Coleman Powermate 6250 10hp Generator Questions & Answers
Generator Won't start
Gap the plug at .030 What is most likely the main problem is whatever gas sat in the carb. Even with fresh gas there will be some old gas still in the float bowl. You may be able to drain the bowl and be OK but I have a feeling that the carb will need to come off and be disassembled and cleaned properly. You can try spraying carb cleaner (I dislike starting fluid as it is too volatile and carb cleaner does just as well in this instance) into the carb/intake. Remove the air filter, open the choke, and spray the carb cleaner in through that way if possible. You can actually keep an engine running by spraying with short bursts. Even by just spraying once you should be able to get the engine to start. If it does start but then will not stay running without spraying more into the engine then it is a carb problem.

The item number is 9 and part number is 070-0056.. This part is around $100-$110.

Good luck

Hi everybody i have a
parts are available from any motor repair /rewind shop
capacitors are only specific for capacitance and voltage and can be obtained from the same shops or from e-bay
the pressure switch only switches the motor on and lets run until the full pressure is reached
it then switches off but switches back on when the pressure drops around 10 psi
If it was doing that there will be nothing wrong with the switch
if all else fails and it is a belt driven compressor get a new motor
The brand on the motor is immaterial as long as it is 5 hp or bigger and has the same voltage rating requirement
