The reg is brand new the lock off is electric and functioning well. I replaced the reg because the machine had a lack of power the dealer said it could be the reg so I changed it. After changing the reg I got all the power back for 3 days and then it went back into limp mode so I checked the filter under the prop tank and it was kinda dirty so I cleaned it out and its still in limp mode. The dealer suggested hooking it up to a comp diagnostic but wants to charge me 110 per hour, I'd like to avoid that.
