Update:
Found a shop manual online. Made adjustments to the carb for high altitude running. Took it out for a test run. For a second it was its old self but fell back into its issue. No power at full throttle. Drove it back home to make some more adjustments & discovered that the Air Mixture Screw had fallen out of the carb. I believe I forgot to put the spring back in with the screw when I cleaned the carb. Couldn't find it. Thought I could get a replacement. Nope! Honda discontinued it. Looked online but no one has it. Even tried looking for a rebuild kit to the carb. Nothing. Have called every place I know of in town. Nothing!
Anybody know anyone who might have the Air Mixture Screw & Spring? I really don't want to buy a replacement carb for this. I'm trying to sell it.
Thanks,
