I’ve just bought a Fastcut 34 with a Briggs 22hp twin. The mufflers have seen better days but I can’t find anyone online with stock. Any suggestions? Thanks.
You won't find one under a greenfield part number, unless someone has old stock. But, they are just a briggs and stratton lo tone, part number 691874 or similar. I am not 100% the variation they used. These can be found for $40-50 if you shop around.
And then if all fails you might be able to fit one of these to each cylinder. Require a bit of fabrication but not too hard. https://www.ebay.com.au/itm/201043747693?
New mufflers fitted. I realise why I couldn’t find them originally - Briggs don’t use them on the twins but Greenfield have used one per cylinder. The new ones needed to be modified slightly to cut off a protruding pipe. Work well.
