Have a 720 gas and am restoring,1st question I had was I replaced some clutch parts that were worn put it back together,when starting it I noticed that the clutch housing was trying to move with clutch disengaged and then it seemed like it was pulling engine down after it started?Do I need to adjust the clutch brake assembly or is it worse?2nd question I let it run for at lease a half hour I wanted to get it warm so I could change oil.I pulled the drain plug and the oil seemed to be just slightly warm,not very warm as I would have thought.It showed good oil pressure while running is this normal,does it take a long time to heat the engine oil?I guess thats all for now,thank you for any insight.
