quote Garry in Tampa:
The problem with some antiques is that the production specs of that era were greater latitude than the precision machines of today produce.. No seals were used and many depended or grease or heavy oil to seal the crank case. (Many Row Boat Motors have grease cups on the crankshaft bearings) Todays oils are fantastic as far as eliminating ware but some antiques may require a shot of heavy weight oil to properly seal the motor. Unfortunately this promotes carbon formation, requiring periodic service to remove. If ignored, carbon flaking off the combustion chamber con score cylinder walls. At none time this was thought to be caused by a lack of lubrication which made them recommend more oil . . . 😆
My understanding is TC-W3 is oil that has passed certain standards. I have thought of using Tohatsu 2 stroke outboard oil.
Can I add one or two ounces of 40 wgt non detergent oil or will this give me problems .. Otherwise can just use 40wgt non detergent. Only plan on running this a 3 or 4 times this summer. Same applies to my other 4 1920 motors.
Thanks for your Input
