OK being the Good Friend I am...I tore this thing down to every basic component and did a Thorough - FAILURE ANALYSYS. This Unit was Run for 1 Season (2 Hours) then Failed to Start. The Blower has a Sticker with Remanufactured in RED. Oh Oh... No wonder it was such a bargain ($100.00)! Probably remanufactured in China??? Well anyway Good Old American Know How has brought this thing Back to Life.

The Initial Compression Test showed 70 PSI? This is the Stated Absolute Minimum for this Engine. Maybe they need to rethink the Minimum? Complete teardown of the unit revealed extreeme Blow-by Piston Ring to Cylinder Wall. Not only was the Blow By seen on the outside of the Piston Ring it was apparent On the Inside of the Ring where it Touches the Piston. The Cylinder Wall looked in Good Condition.
I removed the Old Ring and Installed a New One... I cleaned the Piston Ring Groove until I could see Clean Metal. I then Folded Aluminum Foil 4 Times, Cut it to Size and Installed the Shim into the Ring Groove. I used the New Ring To Form the Aluminum Foil into the Groove. My Friend said Do What Ever You Want... I assumed when this Blower was Remanufactured the Piston Ring to Cylinder Clearance was Over Sized so I added My Cheap Experimental Shim.
When the Motor was reassembled I broke the Engine in for 15 Minutes. This simply required removing the Spark Plug and Spinning the Output Shaft with an Electric Drill. This allowed the New Ring To Properly Seat with the Cylinder.
The Blower was put back together with about 50 Screws, Bolts, Nuts and the Like. The Initial Compression Test was Very Promising as it now showed 120 PSI which is way better than the 70 it had before the Repair. It started according to the 7? Step Instruction and I was Happy. I ran the Motor for a few Minutes and it seemed OK. I am returning this Unit to my Friend with No Warranty but I was happy to learn a Few Things while working on this Motor. I have no previous experience working on 2 Cycle Engines. Maybe I should go work for Poulans? They need some Old Fashioned Yankee Enginuity. . .
