1980 LF oil pump

Good day all, im trying to get my LF up and ready for storage the oil resivour was removed when i bought it and i have put it back on and i see there is a lever on the oil pump itself is that the WOT control?

The lever is proportional - the more throttle you give it, the more oil it pumps.

I can relate to that.

Ohhh I see so i guess ill need a 3way throttle cable then the sled hasnt had oil injection for some time, would you think ill have to pull its apart? still runs like crazy but im worried about a burndown

Yes, you need a cable that runs the oil pump and carbs simultaneously, and the three functions need to be synchronized. When you get such a cable, pull the airbox and set the cables to open the carbs and bring the oil pump off peg the instant the throttle is squeezed. You will also need to run mixed gas until all three lines feeding the carbs and the center crank bearing are free of air bubbles; typically a tank of fuel is adequate. The only function not directly serviced by mixed versus injected oil on that engine would be the center crank bearing. There has been some discussion on this site dealing with this very topic and some guys even run mixed fuel along with the injection system because plugs are cheaper than pistons. Deere recommended using both when air temps are below -20 F.

I've even staged a competition by leaving bottles of oil out in sub zero temps overnight to see which one flows best when really cold. Mystic TCW-3 / BIA compatible in the white container won the last time I did this, but I should try again since it's been a few moons. If I'm out when it's bitterly cold, it seems like good policy to put at least a 25 : 1 mix in the tank just as insurance.

Good luck!
