Oh ! Untouched OEM carb. That might be pretty close for 4000 feet. It will probably be slightly lean as stock for sea level. I'd shim the needle about 1 mm and open up the airscrew a half turn (on this carb, opening adds a little more fuel). That might do it.

120 main and 40 pilot are stock jet sizes. But since you have some elevation, you might not need to change them.

Needle shim instructions are in post #5 in the Templar resource guide but they assume that you've already removed the break-off screws holding the bowl on and replaced them with allen bolt (see post #4 for a link to that).
