Oil injection block off.
- Thread starter cap9709
- Start date
Leave everything in place behind the outer oil pump cover (outer engine cover). No need to remove the pump what so ever,Then loop the oil "in" line to the oil "out" line on the oil pump using a piece of quality fuel line. Make sure there is oil in the "looped oil line" you just installed. Don't forget to put a "cap" on the nipple of the carb where the oil line use to go.
The best/cheapest way is to remove the plastic gear from the pump and block off the injection nipple on the carb.
The 2 oil lines are difficult to splice as they are different sizes.

If he left the line on the carby, you could be ok.
The pump could be damaged by running with no oil, so it could pay to take the plastic gear off.
You really should increase the main let one size to compensate for less fuel in the mix owing to the volume of oil put in.

Why not just do it right,and at the same time change the tranny oil?

Cheap and easy do not come in the same catagory as right, doing it right usually costs a little bit.
the previous owner on mine just cut the 2 lines going into the case. I'm not planning on going back to oil injection, so I don't care if the pump is bad, but would it cause any other problems by leaving it the way it is? I saw the blockoff plate for under $10 but I was wondering if I would need to replace any other gaskets or need anything else? Or should I just leave it alone?
You can just pull pump, remove gear, re-install with new gasket or any kind of gasket sealer on clean old gasket if not torn. Be sure the hose nipple on right rear of carb is sealed.
