all 700s needs the "lo" off the coolant screen. for the trans to operate correctly. take 5-10 mins at low temps . up to 5 mins at higher temps.2021 700-4 I’ve had six months, has 300m/75hrs. Problem in cold weather (teens and 20’s) does not want to engage transmission. Letting idle until oil warms has improved operation. Has anyone experienced this? Also, what about adding a manual choke?
