I've got bad news & good news.First the bad news - whoever owned the last PM55 I acquired should be horsewhipped & then shot.I tried putting a plug in it only to find out that the moron made the plug hole so oversized that a plug won't fit.I ended up stripping the saw down for parts.They oversized just about anything they could,the handle where it mounts on the bottom of the saw was redrilled & oversized bolts put in.On the muffler they drilled holes through the cylinder shield & put longer screws through the muffler & cylinder shield & then double nutted it.Talk about a PITA to get them loose,especially when they're lock nuts.The coil is pretty much toast,the bozo put tape around the coil to hold the plug wire in instead of just replacing the lead.Probably explains why it had intermittent spark.I had to use a small pipe wrench to break the fuel cap loose.They must've been in the oil tank too because the allen screw was in the place of the regular screw that holds the auto oil pump in & the regual screw was in place of the allen screw that holds the tank handle onto the engine/oil tank.
Now the good news - I pulled the tank handle off the 2nd PM 55 to see why the oiler rod was binding.Apparently the oiler rod was not sitting in the groove under the tank handle,from what I could discern.Usually I twist the rod sideways a bit so I can lift the tank higher & have better visuals on it.Normally it seats back to the original position,but not this time.It still wanted to bind a hair,but as I worked the button it works fine now.All I need to do now is put the carb back on.Oh yeah,after I got it all back together I checked for spark & didn't have any.I tried another plug & had great spark.I looked at the 1st plug & saw it had a bunch of crud in between the electrode.I cleaned it out & had spark again.
