Thank you for the replies here. Ed Snyder was not willing to work on and sign off on a Rotax which is installed on an amateur-built aircraft. Apparently he will only work on RV-12s that were factory built.
We were hoping to avoid asking Roger to come up to Carefree from Tucson (not sure he travels that far for work projects?) - but it's looking like that may be our only choice as it seems, thus far, that there are not any other choices here in Phoenix
