I have a gem of a BG55 that I love, gets way more use than the backpack. I saw that a BG85 spark arrestor has a larger outlet and fits so I ordered one. Yep noticeably larger outlet. Screen looks the same. Apparently the MS660 uses the same outlet so it must have good flow.
Well. Stock arrestor, 7170 rpm. BG85 arrestor, 7170 rpm. This is tuned for each one, pretty fat basically just out of 4 stroking when warmed up. The BG85 is in fact pretty noticeably louder.
So. What's the point? I assume a blower, it doesn't matter if it's .8hp or 10.8hp... it's gonna flow the same if it's running at the same rpm.. Am I missing something here?
