Hi guys, I picked up a used 550xp for myself. Photos below.
I am wondering if I should put a new ring on the piston. Doesn't 'feel' like it has a ton of compression.
I do not need to use the decompression button at all for starting, where on my 455 it makes a large difference. It will hang on the starter cord and not drop. Ordered a 10mm adapter for my comp gauge, results soon.
It's inexpensive and easy, only $11 for a ring and base gasket.
Piston is probably OK (will measure) because I still see machining marks.
Hard to get a photo of the cylinder bore, I see cross hatching and not too many vertical lines.
Do I need a new bar? Guessing this is the original bar it came with. Sprocket spins easy. Chain is shot, I'll get a new LPX.
Do I need a new rim? I think these are wear indicators?
Do the decompression buttons leak on these (Are people installing the plug?)
Any reason to move to the newer 2 shoe clutch? $30. Some discoloration but not bad.
Don't know total hours used so I included a photo of the side covers. Only dealer nearby charges $65 to read the hours from the autotune....
Cleaned the mesh filter, removed and cleaned through the oil line on both sides, greased clutch needle bearing, getting a new spark plug and primer bulb. Will pull the carb and make sure it looks ok and doesn't have any crap built up.
Anything else I should check out or replace?
