I have the plane-Robart retracts-OS 91 four stroke engine. When mounting the engine the instructions indicate on page 7 that the "front of the drive washer (or the back of the spinner) is to be 5-1/8" (130 mm) from the firewall" When I ensured that diminsion was correct, I get a 1/4" gap between the spinner and the cowl. I have sent a "EMail" to Tower Hobbies requesting a confirmation of the diminsions but havn't got a reply as yet. Russell Hope, order # 246940097, Customer # HOPE R48.
Has enyone else had this problem?
