I’m kind of a late bloomer myself when it comes to tuning carbs, but with forums like this along with books if one has the desire to learn its really a cinch, for me better late than never. Still absorbing the wealth of knowledge. I’ll tell you one of the best things of having the PV timed correctly for me is getting on the primary throttle only under various load scenarios and feeling that valve come into play and the power thats instantly “now” :thumbsup:
