Some sparking is normal thow,depends on how much? Motors do get dirty from all that Carbon and copper flying around.How old is the motor/how many rounds? The comm stick also has an end to clean & polish the comm. as well as the brush.Last comm stick I bought was $6.00,motor spray $8.00.Might just do the trick!
I'm not sure about a bent comm,could happen I guess.The motor probley would not turn over if it was bent that bad.Sparking more to do with wear pattery and current being pulled through the motor.ie if you were using a M130 spring insted of a stock one,the m130 would need more power to turn over and draw more current than a stock set up.I would just try and clean the motor as you were saying theres no other problem you'v noticed with the gun other than the smell(usally alittle bit) and some sparks(witch is also normal to a point).Next time you use a drill,look in the back were the comm, is,you'll see lots of sparks! Have a good one!

Thanks, for the help. But since I have no experience on electronics at all I don't want to touch the motor at all, but the gearbox is wored when I bought from another user. However, I do remember that some dust metal (When I was filing my M249) the dust metal attach itself to the motor and I try my best to get it out of the motor, I guess some were left behind in it.
The TOP lower gearbox is old design and the entire motor is solder with the wires and attached to the switch and its bitch to take out, but everything else is fine which is good.
I know BC local gun doc isn't available anymore, or at least the well known one.
