7. Install fu el tank, rope start, hook up fuel lines, attach throttle cable and air filter assy, fill with fuel, prime carb and start engine, done.
(Fuel tank grommet very hard to get out, you will need strong hands. When re-installing fuel tank grommet make sure both plastic through tubes are in the grommet and use a little dielectric grease on the grommet to insert it back into the tank. Very hard to insert it so be careful.)
