new top end. how do u break the motor in properly?

i'd start at a prolly very rich 290, you'll prolly end up around 260/270
where you located....elevation ???? < thats why nobody can tell you for sure

googled your towns elevation........594 ft. above sea level

thats pretty low, which equals a larger jet than i would require here at 1800-2500 ft.

start around 290/300, that'll be rich
stock pilot, airscrew at 1 1/2 turns out, needle clip in the middle
