    I was adjusting my clutch arm on my 66/80cc and the head of the screw that holds down the clutch cable to the clutch arm snapped off. Does anyone know what size the screw is so I could get a phillips vs one that's tightened with a wrench?

    TL;DR rest of thread, It's an M4-.70 machine screw.

    it's on the board here somewhere - maybe 3mmx1.0 - same as lock screw for flower nut - I keep a box of 200 high tensile replacements at the shop that are 3mm allen head - work REALLY well

    Thanks, man, I'll go try it out if I can get the headless screw out of there. I'll probably just take the whole clutch arm to Home Depot

    if screw is still inside, I drill it with very small bit and stick triangular handle of jeweler's file in it to twist it out - note also, that hole is threaded all the way thru so old piece could be left in and new screw put in from bottom

    I ended up being able to WD-40 it and just take the needle nose to get it out.

    Also, I bought an M4-.70 metric phillips head and it did the trick.
