A Tail of Two–MS200T–Top Handles & Compression Tests

Recommended Posts

Picked up the helicoil kit on Thursday and sorted out the stripped exhaust mount thread. Did the same on the non-stripped side too - easier to do when you can plug up the exhaust port to stop swarf getting in. Didn't bother drilling just straight in with the tap and a dab of bar oil.


Did a partial re-assembly - top handle and fan housing in order to do a compression test.  Came in at 165psi cold (1,000m altitude)! That's coming from 125psi before the base gasket delete.


Finished putting the saw together and gave her a run. Back in action. I'll make this my primary MS200T for a month or so before doing the same on the other - base gasket delete. Can hopefully improve from 2 month turn around to 2 days.

So far so good. Now on par or slightly better than my 'good' 200T. Powered through some 10" hardwood (Eucalyptus seiberi) before switching to the 460.


Also remembered that I'd put a 7T sprocket (+ corresponding worm drive) into this saw several years ago. The higher compression seems to help maintain the higher chain speed (running 3/8" Picco chain.)
