550 bogging

[northernchris]

If its the same layout as the 560/562xp did they update the cases with an extra bolt across the area below the exhaust?

My own 560xp and 562xp have been faultless running on Aspen, but my 550xp bogs just coming on the throttle, my local deal did a software update but made now difference and said mine was pretty much like all the others???

They definitely did on the 560.

I'm not sure on the 550.

New carb AT12 to much improve pick up.

Have repaired 3 560xps this year with the updated cases all were leaking chain oil into the crank , only had one 550xp in this year with this issue .

Lift the meter leaver on the 550xp just a fraction ! tune it in a big block and see how it feels . trial and error , cures flat spot and hot start issues on most saws . they run very lean stock .
