I'm pretty excited about getting my new compression tester. The automotive style tester I was using was giving me shaky results at best. Small displacement engines all tested rather low. In terms of quality the baileys (actually Trisco) is kinda cheesy. The dial glass is plastic, and seems to fall off, along with the bezel, pretty easy. It does however seem to work as it should. If I worked on small engines for a living, I'd want something better made. For a pro-Sumer hobbyist type, I'm hopeful it will be fine.
Now it's time for me to learn to better interpret the results. I was relieved that some recent aquisitions seem healthy. At least one, is more borderline. At 160+psi cold my Homelite 550 seems to be in fine shape. Similar results for my 046.
My 026 on the other hand is right about 140psi cold. Pulling the muffler reveals some slightly polished looking areas on the piston. Not really scratches, can't feel an edge at all. This saw was a recent find, and needs a carb kit at minimum. At 140 cold, should I put a carb kit in and run her, or re-ring it, or?
