This is in reference to my 044 with low compression. I believe the reason is in timberwolf's post #7 in this thread: http://www.arboristsite.com/showthread.php?t=103543&highlight=044+compression
With the base gasket (.040") and using a .047" diameter piece of solder, there was no squish when the piston was turned over (full rotation, so squish is over .047"). With the base gasket removed, the .047" solder was to hard to be able to get a squish measurement. I got some .032" diameter solder and did 3 measurements (through the exhaust port with a long enough piece to reach the rear and front of the cylinder...I should also do side-to-side to get more accuracy). For the first measurement, I turned over the piston a few times and got .015" and .017" (on each end of solder). The next 2 measurements were with only one piston rotation, and they were .014" and .020", .015" and .020". From reading, I would need to have about a .005"-.006" gasket to get to a 'safe' squish.
In my reading on squish and how to get accurate measurements, I have seen some mention of the timing being different when removing the base gasket. What is the largest squish measurement difference (between gasket to gasket-less) that will affect the saws performance?
