I have that timing tube and it looks like “o” is one of the marks right next it it. However, the balancer isn’t under the timing tab. It forward, the pulleys line up. So something is mismatched. The truck was a 305 and is now a 350. When I look down I can BARELY see the back edge of the balancer.
I’ll probably take the valve cover off and double check the mark and make my own if I have to.

If it didn't stumble before with the timing where it is. It's not stumbling now because of timing .dont mess with the timing. That just adds another variable to the equation. I you are going to make a timing mark you can't do it by removing a valve cover,you'll need a piston stop. I can get real close feeling the piston come up,using a drinking straw through the plug hole.

Im with @Ricko1966, Was running good before. Must be in your carb since you ruled out ignition by swapping parts. Changing ignition timing would be a bandaid.

Ills see if I can take a pic tonight.
I messed with the time, because the wires were all moved over one terminal. I wanted to fix it while the carb was off.

If you get a piston stop, and then find the balancer is one that puts TDC at the 2:00 position, use an aftermarket timing pointer that attaches to two of the timing cover bolts.

Have you checked vacuum advance pod? Is it working? Does the carb have proper vacuum to that port for vacuum advance?

I haven’t checked the vac pod. But, I will. I know the mechanical advance is t frozen. The carb has two vac ports. Right now I have it to manifold vacuum. That’s what the inseems to say for non EGR engines.
The pointer is at 2 o’clock. But, I’ll get a pic.
I always thought this 350 was sluggish. Maybe it will gain some pep.

It’s hard to see, but the shiny part under the water pump is the back edge of the balancer. Plus the bottom view.

Not my pics. But, balancer is spaced out like the blue engine pic a my tab I calibrated like the other pic. Without the water pump everything is visible. Mines not. I will try to mark the line a little better.

I can see how your balancer looks stepped out a little but not too much. It's still under the marker. Is your crankshaft bolt tight?

My pics are the 3 above. The blue engine pics(not mine)are very similar. I would say my balancer is a bit further out. I don’t know when, but I’ll find time to work on it. I have my biggest food truck event of the year coming up. Super busy.

I was mainly talking about your pic of your balancer. Not blue engine
