I have been fly ing since May 2016 and while I had forgotten how it operated when new, I fel t something needed attention. I disconnected the cable from the mixture con trol arm and found the cable to be in great shape, operating very smoothly. Next, I operated the mixture control arm moving it from Full to ICO. Felt g ritty and took 11-13 in/lbs to operate. I called AVSTAR seeking guidance and was put through to Rene (Experimental T ech). After sharing my observations, Rene asked me to remove it and send it to his attention. It arrived at AVSTAR on a Thursday morning and was shipp ed back before they left Friday. Upon its return, I took note that the mixture control arm movement was very s mooth. I reinstalled the fuel servo with the new gasket they supplied and f lew. They had successfully returned the unit to like new operation. Yesterday, Eric (AVSTAR manager) gave me a follow up call to see how things w ere going. I now have 15 hours on the fuel servoand is genuinely g ood as new. Final thoughts. Mixture controls should operate smoothy and we should revalidate full travel . I did when installed, and at each annual. Increased resistance can restri ct the mixture control from achieving full operation. AVSTAR welcomed my observations, understood the gravity of the situation, an d provided a workable solution.
