does anyone on here know where i can obtain the pins and clips that hold the muffler in place on the cylinder head was mowing today and the muffler broke off completely. the motor is a 125cc
Don't wish to be
unnecessarily pedantic here

, but the muffler on a Victa 2-stroke is attached to the exhaust port on the cylinder, not the head.
What shape is the muffler? A squat 'boxy' shape, with the discharge through a hole in the deck?
Earlier Cortinas used a long forward-discharge 'torpedo' muffler.
