hi everyone, new to the forum and trying to figure out how it works.70 years young and computer illiterate! i have a 22 G4 deluxe that wont go forward or reverse. and out of warranty by a couple of weeks, primary clutch blew up, dont know why. weight retainer bolts failed on 2 weights, this is what made a nasty sound as parts were floating around in the cover witch is all scraped up and worn internally. i replaced the primary and belt, both clutches are engaging but will not go forward or reverse.any ideas?
