    I have a problem with my 1982 Husky Auto, the springs for the first gear clutch broke and got chewed up. I had some springs from a parts engine but when fitted the engine stalled every time I tried to engage gear. I rolled her down the slope on my drive and managed to get her into gear, she then changed up and down the box fine but every time I slowed down the engine would not disengage and would stall. I originally thought the springs from the parts engine where tired, they were easy to fit, and not holding the brass weights back. I then managed to obtain a new set of original springs and fitted those, they were a bit harder to fit, I also cleaned up the grooves as shown in the workshop manual. However exactly the same result stalled, when I tried to put it in to gear. Pushed her into the back of the shed so I could have a good sulk.
    Tried again today , stripped clutch and refitted, checked the freewheel bearing, perfect, reassembled but no change, the first gear clutch seems to be permanently engaged, stalls every time I engage gear and after using the sloping drive trick again , the engine will not disengage from the clutch. The next stage is a box of matches but before I take that step any ideas please?:confused:

    How did it work before you replaced the springs?

    Problem solved by some advice I got from OZ forum. When I was torquing the clutch drum up it removed the end play and made the drum bind hence the permanent drive scenario, I guess the crank got moved slightly when the springs broke and got jammed against the cover. [IMG]

    That is good to hear you got it figured out because I couldn't think of anything short of shortening the springs. Just from memory and it is at least 15 years ago I had one of those apart and seem to recall the drive end of the crank had moved out from the crank wheel perhaps half a mm or so. I think I made a jig to push it back in but ended up buying a new crank as they were the least expensive crank of all the available ones for some strange reason and mine had some strange pitting on the rod. I find it hard to vision how the crank could shift much in the bearings, the ignition side bearing might be able to shift out in it's bore.

    I am happy to hear that you solved the first gear problem and you got your carburetor issues sorted. I am also happy to hear that you were able to find some new first gear springs.

    I would like to buy a new set of springs for my 420AE before mine give up the ghost. Can you point me to a source?

    I might be in the UK on a business trip the end of July so maybe I can pick them up then.

    Thanks, Steve
