Here's an update on my '69 Thunderbolt project:
The first shake down ride ended with a damaged valve train. A rocker and a couple of push rods later and I was able to take it out today for a second ride. The first time out I had, what I thought was a Amal issue, but a forum member taught me that a lot of carb issues are electrical. Which was very helpful advice since I had incorrectly built one of the spark plug connectors. This time around the engine pulled better and did not crap out at mid RPM. I did not attempt to push to max rpm, but I think I assembled the intake valve train correctly this time and the electrical carb issue seems resolved. The engine over all sounded much better, fingers crossed.
I need advice troubleshooting and sorting out the shifting issue which remains from the first ride.
In my previous post about ride one, the forum suggested a weak shift lever return spring. The only thing I changed so far was the position of the shift lever. I thought I might have installed it a bit low and perhaps was riding with my foot.
Again Neutral to 1st was a solid clunk, Neutral was easy to find. 1st to 2nd was also nice and solid. The shift from 2nd to 3rd nothing.
In the last post someone mentioned that perhaps the lever isn't returning positively. To test this I very lightly pressed down on the shift lever then up shifted to third. It was very sensitive and I did manage to hit third once or twice. Even then it took three or four attempts to get the shift right. I didn't have room in the neighborhood to go for 4th.
Now that I have it running. Are there more test I can conduct while riding to better troubleshoot the issue?
Do I need to pull the outer case and have a look at the _______? Return spring?
Do I have a problem deeper in the transmission.
