Small Engines (Lawn Mowers, etc.): Where to find replacement piston ring?, piston ring, compression ring

Question
Greetings,

I have a need for a new piston ring for  McCulloch MS1635AV that was given to me.  I'm having trouble finding a parts dealer for this beast.  The old ring (what's left of it) measures 41mm dia. at rest and is 1.6 mm sq. in section.

Any ideas for this part?

Dan

 Hello Dan:

 Go to this Addy http://www.buymtdonline.com/webapp/wcs/stores/servlet/topcategory_10101_15601_-1 and Click the Launch Search Engine. Then Select the OEM(McCulloch) and Enter the Model Number. Then Double Click on the Model in the Search Results Area. Then Select the Powerhead Assembly. I Looked at All 3 Saws Listed and the Compression Ring is the Same for Each. The Compression Ring Number is McCulloch #301284. You can Order the Ring from this Company Also. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John
