Out with the 340 & in with the 410 stroker!

Checked plugs, the porcelain is white with a nice brown ring down at the bottom, timing shadows are right at the bend on both sides of it, excellent.

Still gonna lean it out on the primary till I get just a lil surge and then step it up.

Jets are 72's so far and going 71's next test, that should put it in the middle.
