Tuneup part 1

The car ran but ran really rough when I got it. Had to crank for a while to get it to start, and it would pop and backfire if you ran it much above idle. The mufflers both have fist-sized holes in them, so it’s probably not the first time it’s backfired.

The timing was waaay advanced, off the top of the tab at idle with the vacuum advance disconnected…probably 18-20* or so? Pulled that back to about 8 initial, and verified the mechanical and vacuum advance was working.

Adjusted the valves a bit conservatively to make sure they weren’t staying open from too tight lash.

Sprayed a bunch of gumout in the carb and that seemed to help…so I ordered a rebuild kit.

Adjusted the idle speed and mixture, and verified the electric choke is working properly. idles pretty smoothly now, but still popping and backfiring when I get above 1200 or so.

Siphoned as much as I could out of the gas tank, didn’t look bad. The fuel gauge seems to be working too… I put in a couple of gallons of fresh gas and a splash of sea foam.

I was bummed it wasn’t running better so I figured plugs were due for changing too. Local auto parts place didn’t have plugs in stock for it (really!?!?) so they put in a warehouse request.
