the inlet valve had no clearance, so i took a bit off the stem, it now has about 8thou clearance.the inlet valve is starting to close around BDC, the valve is still closing as the piston is coming up on compression and still backfiring through the carby, its now trying to start but wont, its a lot harder to turn over, i checked the flywheel key, its ok, something is out of wack somewhere, i'm starting to think i'll be stripping it down for the answer to it all, i've never seen one break a tooth unless its a major hemorage. this one was running but now i cant get it started at all it just sounds like the timing is out by a mile. anyway i'll see what tomorrow brings, cheer micka
