Olds 88 1960 misfiring problems
Hello, I’ve got a olds 88 with some major misfiring issues. Starts sometimes, but it runs really rough. If I give it a bit of gas it wont rev but missfires instead.
Ive replaced the carburator to a new one
I checked the timing chain so it lines up with the cam wheel (the two dots facing eachother) but cylinder one isnt in TDC when they match up
I’ve adjusted the point breaker to .5mm
Ive checked that every cylinder gets spark
Ive checked the compression on each cylinder
Ive set the timing so it at least should start
Idk really whats more to check or replace?
Hope some of u guys could help me out
Thanks

The specs for the Olds 394 engine say: "Turn adjusting screw in until engine
begins to misfire, then back screw 1/2
turn
You say you set the points at 5 mm. I am not a thoroughly conversant on the conversion, but I believe that comes out to nearly .020. You might get better results by narrowing the gap to .016 or 4 mm? Timing should be set at 5 degrees before TDC.

I've learned to look at a new poster's profile to see where they are and looks like he's in eastern Europe, which might explain his metric specs. 60, if you can find a dwell meter/tachometer it will make tuning your vehicle easier, especially since your car has externally adjustable points. Those have gotten hard to find in US so don't know about finding one on the Continent.
