Hello,new to this site. You guys are a wealth of knowledge.I have a B&S 3.5 on a Scott Bonnar 17inch. I recently pulled it apart, replaced a few low $ value parts, cleaned it up & put it back together. Runs well except for the fact the clutch slips to the engaged position at times without touching the clutch engage lever. Also when the clutch is not engaged the shaft still spins rotating the reel.Believe the cork is still ok (have around 3-4 mm left). At present the clutch appears to be secured hard up against the engine side. Is this correct & should there be a few mm gap possible? Is there any other adjustment necessary? Any help is appreciated. Cheers- Ross.
