[Spridgets] Racer guys Engine help

[bmwwxman .]

What Mike said.....    I've seen this happen before too.  On my MKIII
Midget I have to rotate the dizzy 180 degrees from where it *should* be.
You could try that too.  I've known a number of different 4 bangers where
the dizzy was 180 degrees out.

Cheers!!
