All thoughts appreciated.
I have a 60 that will run fine under load but as soon as you un load it the engine starts to surge in rpm back and forth. I know about the idle passages and while I didn't remove the steel balls when air or cleaner go through the passages it looks like it comes out the proper location fine. It was soaked 24 hours in carb cleaner and re built.
What I've tried so far:
1. Adjust idle needles which seem to not do anything for how it runs.
2. Removed cylinder plug wire on each piston and noticed one has a dead miss until it goes under a load.
3. Adjusted throttle linkage to proper length per the book with no indication of idling better.
4.Checked timing and points and reset everything per the book, no help.
5. Rechecked idle passages to verify they are clear, seem to be with the air and cleaner test. Balls weren't removed.
6.??
I'm starting to think there could be a bigger problem than the carb.
Any ideas?? I used it all summer like this but it is eating at me to get it to run properly.
Thanks,
OldCrow
