A couple weeks ago StihlyinEly had most of a pair of 028s for sale in the Tradin' Post. I was about to go on spring break (a perk of teaching) and needed a challenge, so I bought his saws. This is what he sent:
Everything came promptly and as advertised (thanks, StihlyinEly). I'd never taken on a saw in parts, much less two of them. Fortunately, I had plenty of time to research various questions here on AS.
The saw with handle attached went together pretty smoothly. It passed pressure and vacuum tests and compression is 160+. Its carb did not pass a pressure test, so I used the loose carb which did pass. The saw started up after a half-dozen pulls. I hope to give it a workout this weekend and experiment with the tuning (something I'm still trying to master).
There were enough parts left over to tempt me to complete the second saw. One problem - the case was broken where the upper AV buffer bolts on. I couldn't find any encouraging words about welding magnesium, so I tried JB Weld. I got the idea from some other repairs I'd read about here. First I drilled some holes for wire reinforcement.
Then I wire brushed to get paint off and roughen the surface.
Finally, I built a clay dam to contain the JBW. I greased up the bolt and ran a screw through the clay to hold the bolt in place. Finally I dolloped in the the JBW. I had to balance my desire to poke around to eliminate air bubbles against the risk of moving the bolt out of the threads.
More to come.
