puzzler for ya

thanks all!

after work I'll take a look inside the No.2. I think I have a little screwdriver with a magnet mounted on the end . I'm a little freaked out about loosin' the magnet in there!! You know, there is this gap between the Weiland 8007 intake and the head? I've dropped one of the choke screws in there before. Took a couple hours with a magnet and pliers to fish that thing out.

I fixed the gap and cleaned the contact already. It just looked like it got dropped or something. (both times) They are Autolite 66, they were new (and set @ .35) after the last time this happened. Suppposed to be "hotter" than the 65 which crossed w/ Champion RN12Y

My fear is that yes, it's the piston, and things just are not set up the same in there. If so, can I use a plug with a slightly shorter reach? can I double up on the washers?

when the gap is ok this thing runs fine normally, It only happens when I punch it.
