Two things. I have weak spark, both cylinders. Where do i go from here? what output voltage do i need?

Next thing, the oil fill screw is missing. It looks like the threads on the case aren't original and re-tapped. i get a weird size according to my thread gauge, 13 thread pitch, it's about 7/16 diameter. Not an SAE size.

3rd thing: The link between the tilt lock/release lever and the tilt lock is missing. I need to see how it links up.

thanks for any information

1973 Eska with Tecumseh powerhead. Solid state ignition no points. OUCH.. I have the repair manual in PDF if you would like a copy. Private message me your email and I will send it to ya. Finding the ignition is gonna be a bear. A couple of people have re-manned their own. Modified from old tractors and such. You could google it and see some of the ideas.

Might it be a 1/2" pipe thread?

It had a funked up 1/2 x 13 nut in there but I can't even get that reseated.

the oil fill screw is m12 x 1.5 metric. is that the factory size?

i'm going to test the ignition module output and go from there.
