Sir please help me!

my stupid dad had a customer who filled a gasoline jug with somewhat diesel and gasoline, what the ratio is I don't know!

But now I mixed it with 2-stroke oil and ran it through a 2-stroke 26-30cc lawnmower. It runs funny then dies! what should I do!?

@Naturepheonix Drain out the gas and put some fresh gas in the tank. You may also need to drain out the float bowl from the carb.

[Naturepheonix]

@motorsportscooters Oh crap! what is a float bowl sir?

[motorsportscooters]

@Naturepheonix Just change the gas in the gas tank first and see if it will run. If it was running well before it should be ok.

nice job! i like to put wood in between that vice and cylinder cuz last time i broke the cooling fins

[motorsportscooters]

@3970010 Yes wood is a good idea or soft jaws would work even better. We don't clamp it down that tight, so we haven't broken any fins yet, but the fins are very fragile.

@Scootologie - i've seen alot of manufacturers that don't do it :( - I always chamfer them just to be sure.
