We started an old mf 1800 today the guy that owns it hadn't seen it in 10 plus years the solenoid was stuck but jumped the terminals and as soon as the stater caught the ring gear it roared to life it ran good but the hydraulics weren't working I think it just needs run awhile my question is it was pouring out white smoke while we ran it for 15 min. I think maybe it ha some stuck rings if we put a little ATF in the fuel and ran it awhile would that help free them? I know its not antifreeze I checked the oil and the radiator never went down its going in auction in 2 weeks but thought it would give it a better appearance if it quit smoking as bad
