Workin on a km4 ris. Took apart my gearbox to grease up and upgrade. Been a long ordeal, but got everything together. Got the plugs sort of rigged up without heat shrink wrap to test it and everything worked. Pulled the wiring through the stock, wrapped, got it all set up, and now semi works fine, but when it's switched to auto it shoots on it's own with no trigger response. Any ideas?
