Why It Matters
A big-bore engine spinning hard wants a generous pour of fuel at wide-open throttle, more than the middle of the range can give it. Reach for this 135 brass main jet when large venturis and smaller jets leave the top end running lean.
The 135 is a rich step for big-displacement, large-venturi engines, for when large venturis and smaller jets leave the top end running lean.
Installation Notes
Tune the main jet a size at a time: fit the jet, read the spark plugs, and step up or down until the mixture is right from cruise to full throttle.
