Point Bounce Anyone?

So I was headed into work a few weeks ago & since it was a nice day I was taking Tonk.

Decided to take the highway for a change & about 2 minutes into the 60 MPH+ period the engine backfired & died

Coasting off to the shoulder I quickly discovered that the points in my dizzy I bought from Walcks, with all of about 500 miles on it, had busted- the steel tension spring has snapped right at the end.

Thankfully I had a spare set I bought from Walcks , just in case, at the beginning of summer.

Got then in, sort of set, & managed to limp home with an engine miss.

Played with it a bit off & on but I had time today to really dig into it.

I'm idling very smoothly at around 800 rpm, timing is set to 5 degrees BDTC & dwell is at about 42 degrees.

When I give it gas the dwell starts dropping & the engine starts missing & will not pass 2000 RPM.

While the "old" points had a single steel spring, the replacement set have a copper strap with a steel C-clip kind of arraignment that honestly doesn't seem to do much.

To my un-calibrated fingers there doesn't seem to be much tension on the points, I'm wondering if the little Boogers are bouncing.

Input anyone?

Apart from "pertronix"??

?

 

Bounce as in lobe action throwing them open past the set gap? Wouldn't surprise me.

 

Yeah no way there's anywhere near that much tension, I'm wondering if maybe the c clip thingie is supposed to go on the "inside" of the copper strap.

Should be only one way it will fit right.

 

That's it- iIgot it together backwards

Thanks Pete

Glad you got it! Obviously it runs better now.

 

I'll get to it tonight, let you know tomorrow.
