My suggestion....Drive it...then tune it....drive again...see how it cruises...see how it performs. There's an old way to check if your running lean or rich...while the engine is cold you quickly run onto the road and Hammer on it...I'm talking full throttle through all the gears...then shut the engine off and come to a stop...pull a plug...if its black your running to rich...if its a clean burn..your fine...if it looks like things got really hot...then your lean or you may need to back your timing down a bit. Haven't done it myself, but I heard it works from the older guys I have talked with. I'd leave the carb as is...turn the A/F screws in until the engine struggles to run...then back out until max RPM is achieved. The reset your idle if need be and drive the heck out of it.
