missing gasket
by Big from Big Lake, Alaska on September 21, 2013
When I received the package I noticed the Gasket Set had been opened and then taped shut again. Inspection revealed that the Carb to Block gasket was missing. Luckily I was able to reuse the old gasket but was miffed that I had to.

Will Part # 500-221-05 fit 225 dfi?
No it will not fit that motor. We will need to know engine serial number in order to confirm gasket set.
