Trucks been a sputtering

[CG]

My trucks drives round town just fine, but when I get up to freeway speeds she'll sputter now and again. I figured something wrong with the dist. Finally got off my lazy rear and popped the hood...blah..still has points dist. I swear the original owner told me he upgraded to HEI.

So Ive been putting off doing the HEI upgrade, but today I needed to go to the dump. So I figured I would just put new cap, rotor and points in there for now. Pulled off the cap and looked inside...yep a little worn...went to pull of the rotor, one of those round ones...it had studs coming up from underneath with nuts holding it on. Weird and then I noticed there were no points??? Turns out its a Pertronics distributor set up.

I tossed a new cap and rotor on there and it zooms right on down the road with no more sputtering at cruising speed. Damn happy I didnt have to put points in it or do an HEI upgrade.

The one thing I do wonder though is if this is the reason my tach is sometimes right on and sometimes waaaaay off.
