Sounds a bit healthy on the oil, Rob. What year?

I have no idea Richard. I cant find much on the motor other than it says Commando Motors on the front and has a model # t-642-04c

Can't answer your question but that is one of the best uses of pvc I have seen in a while, very nice.

The one sticker says a pint to a gallon of gas so I would go with that since it is right on the engine, seems like alot but those older engines really liked the oil.

Thanks abf. I like to stand sometimes when I fish and the outriggers make it super stable. They are easy to take off for transporting or for a lazy river outing.
I thought that 1/2 pint per gallon was a little much also but I guess Ill carry a couple spark plugs along just in case.

Try posting in the "other brands" forum. The guys that hang out there have heads full of memories.

My 2 aftermarket manuals covering many brands 61-70 all Commandos are 16:1. They use a Tecumseh powerhead.
Manual; covers Commando and the Tecumseh powerhead.Power heads are classed "split crankcase" and "unit block"
You probably know these are air cooled and the leg is not cooled.You can use a good 2 stroke oil or a good TCW3 rated oil.

Thanks steelespike. I took it out yesterday with 16:1 TCW3 and had a couple extra plugs on hand just in case but didnt need them. The motor ran great all day. I could get 6.5 mph on the gps on the canoe pictured above. I knew it was air cooled when I picked it up. I dont like to worry about impellers and water cooling.

Me think air cooled OB's run hot and require air-cooled type oil (super 2 stroke) ... not Tcw3 type oil for water cooled motors thar run just warm.

Holymosesmgr, you have hijacked a thread. Bad forum etiquette. Please start your own thread.

Rob: you can use TC-W3 oil or chainsaw oil. Is there some mystery involved in the very clear (to me) instructions? They do say exactly: "16:1 with outboard oil".
