I've had a Tanaka 3.0 for over 30 years now...real easy to make it run!....Very simple motor design. Some parts not so easy to get but e- bay, etc. may allow for you to just buy another running or not running motor for parts. Regarding the fuel lines I replaced all mine with clear/yellow plastic fuel lines from local chain saw/weedeater store(try Home Depot or Northern Tools)....they also carry nice little plastic fuel on/off valves and in- line fuel filters....all very cheap and easy to cut and install. The spare parts motor I mentioned can be solid gold for certain items like recoil starter springs, lower unit parts/gears,bearings, etc. Good Luck!
