| My 17.5 OHV needs a new carb, it runs really lean and i’ve broken the mix screw. So I’m wanting to go ahead and upgrade while i’m at it.
What are my options for a better carb? I’d like a Mikuni clone but don’t know what size I’d need.
Thanks | |

| diameter = sqrt( disp ) x 2. sqrt being square root. that's a 31ci as I recall, so 507cc give or take. rounding down to 500 (close enough) square root is 22.3 and some decimals. x2, rounding again, 44-45mm should be fine, could even go down to a 40 with jetting. Will need tuned of course, but will be in the ballpark | |
