85 2 stroke leak down and oil injector

[CoachBob]

I posted a general thread on this build and have a couple of specific issues to ask about. Here are two video. One will show a noice on **** down. I have not done a proper leak down test yet but am pretty sure i have a large leak because i have no pulse at the fuel pump port. I also assume that is why the previous owner put am electric fuel pump on. Is it possible to get a good soap test goi g with the engine still installed?

Next video is of oil injector test. I did not change the line or filter, so wondering if perhaps i have a clog rather than a pump failure.

I don't understand how it's even running, if you could call it that. No pulse means there is a major air leak, but that thing sounds so bad, I think there is another issue. Pull the exhaust pipe off, and look at the side of the Piston. If there is a square hole in the side, it's in backwards.

It won't run with the oil line off because of the air leak. It only flows a small amount of oil at speed.

I’ll do that. Thanks. I’m assuming I’ll probably have to rebuild this engine top and bottom regardless.
