Chainsaw Repair

Ray -  Thank you very much for providing the manuals, really appreciate you taking the time to do that and they are very helpful.

Term - No, I removed the limiters

660 / All - Question on the pressure/vacuum test: The 600 SM just states it should hold pressure & vacuum, several posts here and elsewhere indicate the pressure/vacuum will drop off, 660's earlier post stated "should not loose more than 1/3 of the test pressure within 30 seconds.".  Which is correct?

After tinkering with the setup for a good part of the day and finally getting things to a point I trust the results, my pressure & vacuum tests both fail.  I checked around the block off plates I made for the exhaust and intake and around the cylinder gasket didn't show any leaks, though I will test further tomorrow.

I now believe I need to remove the flywheel and clutch to check the seals.  Planning on using rope/wire inserted into the cylinder to safely stop the piston and I will rig up something for the clutch removal.  Couple google searches show various options for both stopping the piston and pulling the clutch and I'll do some more googling on removing the flywheel.  Hopefully I can find time to work on the saw tomorrow.

Thanks again for the tips and feedback.
