I have a 2002 m115a2 and swapped it with a m140a a older motor, I kept same controls because I thought it would be plug and play, the 140 when hooked up to hose seems to be in limp mode only getting to 2800rpms then starting beeping, I read somewhere it may because controls aren’t compatible but there is a bypass, the 140 had 2 plugins but the 115 it only had one that was needed.. Any suggestions?
