Hi all, I have a Victa that has a 3.5 Briggs motor on it, it has the plastic governor flag and the governor spring and anti-surge spring type. This thing starts first time but has no throttle response, runs full revs all the time. I have replaced the governor spring and anti-surge spring, I have adjusted the post that the anti-surge springs fits on to, to a back and forwards position, but that doesn't change the revs. The springs are fitted correctly and the fuel tank clip and rubber seal are in position when the tank is fitted. Any ideas?
