Got the 110 mounted. 5-1/2" from back of spinner to firewall. Nice and tight to aid in balance, No chance of the blue stripe lining up now. A new cowl is in order, with the existing access holes and the new ones required, it will look like swiss cheese. Got some plumbing to do and relocation of the throttle linkage. Then its balance time. Work is interfering with pleasure, as usuall. Joe
