Ics m4a1 help!!!

[Apurturesci]

Hello. My beloved ICS plastic bodied M4A1 has....well....im not sure really.This morning it started to fire accasionally in fully auto, even with the selector on semi. This evening I looked at the upper mechbox and and saw that the first tooth on the piston had been stripped off. I replaced it with a Systema one, ans everything seemed alright till I fired it again. The ROF on a 9.6 was down to aroung 600, and lowder than ever before. It still fires in FA when it likes and sometimes all I get from firing is a click, or whirr of the motor. When a battery is connected, the wires heat up and the motor is burning hot. I think it may be something to do with the selector plate, but Im not sure. Any help would be greatly appreciated.

Sounds like the gears are jamming up. I think the piston teeth are not properly aligned with the sector gear and are causing it to sporadically jam up.
I would recommend getting a different piston and seeing if this changes, trying to realign the gears (give them a reshim while you're at it) and installing a sector chip on the sector gear.
I can't think of any other reason off the top of my head. See if installing a new TM or ICS piston changes anything.
