It would be interesting to see how well they handle dirty gas, like maybe intentionally test them and see how easy it is to rebuild them?

Actually, that's what I'm wondering-hard or easy? I've never owned a chainsaw haha.

I'm just wondering if it's easily rebuild able or if it needs parts like quadrant carbs and the like. I run a filter but I still premix from a can so I'm always afraid of dirt clogging Mt carb n killing my commute.

I've read that snowmobiles and dirtbikes and chainsaws use these mainly because of the frequent altitude changes, not any performance reasons tho. Racing 2t guys seem to like flat slide powerjet carbs.

They require parts. 1 part; the diaphram, which degrades and breaks down over the years. Kind of like the float valves in OEM carbs; replacing those was an every 5 year job on my GS500.

Frankly, anyone into modding these engines isn't on a 5 year useful life horizon... they want more power than that. So I don't think it's a legit concern.

If there meant for high performance it would be understandable if they had certain drawbacks, I'm not trying to take them down or anything. My main concern is low quality gas, which we have alot of here in the Seattle area. One theory I've heard is its the humidity and pollen in the air building up in the gas-and i beleive it. I'm running a new petcock and a new in-tank screen and have a fresh filter on it, and I still take the carb apart and clean it once a month or so, and it always seems to have something in the bowl. I'm starting to use mine more as a commuter, and I'm interested in these carbs but not if I can't take them apart, spray em out, and put it back together w/o replacing seals or the like.

Actually I've seen a few guys on here taking there modded motors to 5 digit odometer readings and/or getting several useful years out of there motors. But I'm not really worried about longevity, things will always need maintenence.
