Took the clutch off (fun without the special tools) and this saw appears to have the wrong oil pump in it. This pump has an adjustment screw on the end which appears to be the one for the 410 and 411 models. The one for the 340 looks like it has no adjustment. Am I correct on this? The worm, which looks just like a pc. of spring, wiped out the small plastic spines on the oil pump shaft. Thanks for any help, the new bar and chain are waiting! The sprocket doesn't look bad, but I'll change it for the new chain. Kenny
