Shut the gas off on the pony and idle it until it runs out of gas to shut it off after starting the main. The mag switch should only be used in emergencies. If not the crank will soon be out of your pony. The pony only holds a little over a quart of oil and soon becomes diluted with gas caused by the juggling needle valve in the pony carb. Standard paragraph in every operators manual for all pony start machines. I would be careful on use until I acquired manuals and took time to read them.
Good info but that pony actually holds 2-quarts oil.
