Well, decided I would try to tackle the saw today, and by that, I mean take it to a professional at the saw shop!! :P
We (owner, worker guy, and myself) all took a look at it during coffee this morning. When I finished building the saw 7 months ago, it tested out at 157 PSI, which was very good. This morning it tested at 64 PSI, clearly something is wrong.
Took the spark plug out, looked in there, still looks like new! No scoring, no heat marks/discoloring, nothing, clean. Take the muffler off, same story, everything is clean.
Now we are "sure" it is a crank seal / bearing, HAS to be, right?
Psssshhh. WRONG! The entire jug is LOOSE on the crank case!!!! It is a wonder it ran at all!!! Got a new head/jug gasket coming, and a new muffler stud, and it should be good to go....
When I put everything together, I torqued them to the specs of 25 Inch Lbs per bolt. Owner of the shop told me that I HAVE to use some kind of a Permatex / Thread lock, so, I bought some Red, high temp for the 4 bolts that hold the jug onto the crank case, and I bought some Blue, Medium Duty for the muffler studs (can't keep them tight, and lost one.... :)
So, long story short, what could have been a costly, time consuming disaster turned out to be VERY lucky! Better bump up my cleaning and inspection schedule!!! :o
Hopefully soon enough it will be back to killing trees... Miss the big ole thing already!! :(

Today's Featured Article - Timing Your Magneto Ignition Tractor - by Chris Pratt. If you have done major engine work or restored your tractor, chances are you removed the magneto and spark plug wires and eventually reached the point where you had to put it all back together and make it run. On our first cosmetic restoration, not having a manual, we carefully marked the wires, taped the magneto in the position it came off, and were careful not to turn the engine over while we had these components off. We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
