Yes that’s when my problem started.
I had first set the valves when it was not running when I first got the engine.
The carb rebuilder restores the carb and set it on a 350 they have at the shop so
I havnt not messed with the carb.
Once I got the engine started the first tome, I set the timing to
12 degrees.
I sounded like it was running great.
And all my plugs are in sequence, not crossed wires, everything there I checked and double checked.
Then one do I started her up, let it warm up, and noticed it was not running the same, the engine was shaking really bad, sounded like it was mis firing and when I checked the timing that’s when I noticed that the balancer timing mark was off 2 inches.
Now that’s where I am at, I first tried changing the balancer and have the same issue with the new balancer.
Then started checking everything and that’s when I found the loose rocker and the then found out that I had to
Tighten the rocker down so much to get it to open the valve.
Right now it is still running poorly once it warms up and in idle.
When I start it up cold it sounds like it’s running smooth.
Right now I have it timed at where I could get the highest vacuum at 16” and that is where I could get the engine to run the smoothest.
Skipped tooth on the timing chain?? That sounds like that could be possible, maybe that’s why I can’t get the distributor to get the timing mark anywhere close to the pointer.
When I do turn it so far advanced to reach the pointer, the engine shakes so bad like if it’s going to die so I don’t even try anymore. That’s happened only once. Right now I have the carb off.
I was thinking of pulling off the manifold and heads and see what’s going on there
