I have never used a 4 stroke engine and I have a .71 Magnum 4-stroke and have it mounted inverted. Is there any tips on how to cut the cowl? I will have to cut the bottom i know to get at the glow plug and a hole for the exhaust and a hole for the needle. If im using an electric starter do i need to have the choke assembly on since i dont plan on priming the engine before i start it. Also if the glow plug is on the bottom how is the best way to us the glow plug starer. I know this all probably sounds obvious but any hints and tips would be great.

Thanks,
Brad
