Another carb question

That is about right.
These old school piston ported two strokes are actually running about right when they run as you've described. You could go a little leaner and listen closely to the engine....I'd bet it still four strokes at no load conditions, and you'll maybe get a slightly better run at lower speed throttle settings, but it will run too lean at or near WOT or higher rpm.

See my signature....

I went from the stock jet to a #68 Dellorto and noticed a huge difference in top end performance while relying on the needle clip adjustment for off idle to WOT bogging. Thats just a bit smaller than the stock one, im waiting on another at the moment, a #65. I let you know how it works out.
