Very common to us. Low speed jet is plugged. Clean with small wire or a micro drill bit very carefully. That jet is a tech item so don’t enlarge it. Referring to #40 low speed jet. Drain the fuel after each race day. We have an appropriate sized micro bit and an extra jet and as a matter of course change or clean it every morning before racing.
