Hi All
When working on modern saws,pressure/vacuum test is so important when rebuilding or assessing an unknown saw.Pull the muffler,wiggle the bearings,block off carb and exhaust and vac test...
Now with the antique saws with the swivel handles for the pre diaphragm carbs,how important is the vacuum test?
I have a 26LCS Homelite tore down to the block and decided to do a Vac/pressure test.The flywheel seal was leaking.I am trying some concentrated oil seal conditioner from Rislone to see if it brings it back.
I am thinking that the swivel on these old saws will leak now,were they ever tight from the factory or did the massively inefficient carbs of that era dump enough of the 16:1 mix into the saws where they never had a chance of leaning out.
Thoughts,Theory's ?
Thanks Thomas
