As the engine got to full temperature the compression would leak past the single piston ring, causing a loss of vacuum, which reduced the airflow through the carberator.

The new piston was redesigned with 2 rings and shape changes that worked with the improved porting in the new cylinder. The cylinder assembly included improved gaskets and heat shield that the original engine did not have. I spent a lot of time cleaning and making the leaf blower look brand new. The only moving part not replaced, was the crank shaft, so I effectively have a new engine, which is better than it was when it was new.
