I have an 880 in the shop…first one I’ve worked on. Mainly needed a good cleaning.
the carb was full of crap so did a basic sonic tank and reassemble with existing kit parts as they were in great shape.
pulling the needle valves I found tiny o rings…wasted, of course (2009 saw).
I didn’t have anything that small in 3 different kits so ordered some.
new kit had something close so…
saw runs well.
but…should I find some OE Walbro rings for this thing?
I can’t find the specs on the oe rings but have a message into Walbro in AZ.
main reason for the question is I can’t get (manual spec) 11,000rpm without dialing the H screw in more than 1/2 turn. That doesn’t seem right to me.
muffler mod making it a dual port so about double the OE opening in total.
new, OE air filter, new fuel filter.
