Thanks... your suggestion worked just fine, but now having second thoughts about whether this is a basket case or not. A little background.... I got it used from the well known auction site. This Webra Speed .61 turned out it to be a Metric version... external appearance pretty much the same as USA version, 8mm crankshaft, beefier conrod, different design crankcase (a relieved area to allow the larger conrod clearance, different engine mounting pattern), don't know about the bearings. Had flown this engine maybe 50-60 times, most recently in the Dirty Birdy ARF. That flight ended early (about half way through) with a sudden engine failure from full throttle to dead (engine was not running too lean). Dead stick landing was successful. The engine appeared to have virtually no compression. It could not be restarted. Checked glow plug... it was OK. Took it home, looked at it the next day, and even cold, virtually no compression. I don't know if I should trash it or if a new piston ring would restore compression. Because it's apparently a Euro-version engine, not even much good as a parts engine. Any thoughts?
