    I need more tach out of my A/C 25 it' running at 3780 right now and with doubles it cuts back to 3600. I can move the Governor linkage by hand when it's wide open and it will go to 4200+ I'd like to have my tach running in the 3750 range with the doubles turning. I'm not real worried about waranty, I'm tired of going slow.

    If you want more blade tip speed you should change your pully that drives the spindles. We changed one on our Z-Master and got alot higher blade tip speed! By doing this you would elimenate engine damage do to higher rpm's if you messed with the governer!!!!
  8. I think in 2001 that started offering them on the entry level machines..

    No coolers, no donaldson/nelson, no amsoil.

    is anyone using a hand held tach? clip one wire to a spark plug lead and the other to ground? is it different from a single to a twin? my hustler z seems powerful plenty, but there are times when grass slows me down.
    would changing to a smaller diameter pulley rob power when cutting in the thick stuff, would't that slow you down further by making the engine lug down trying to spin those small pulleys?
