Use P.A.W. fuel tubing or Aerotrend Aqua Blue Diesel fuel Tubing. Red Max will make this blend for you. Once the fuel has been in a plastic fuel bottle, it loses some ether. The less ether in the fuel, the harder the starting. Never store Diesel Fuel in plastic containers.
Diesels leave a smelly, oily residue.
Fill up the tank, and put on a thick glove or finger shield. A piece of rubber hose works well. Mel Lyne and Remy Dawson. If it still doesn't fire, give it 1 more choke. Try not to flood the motor.
