Re: serious loss of power
got it from a gasman resaler near fairy meadow (south of sydney) i stripped it bare just yesterday and cannot see a single thing wrong with it. put it back together and it still has no power. it will get up to speed on a flat but the 1st sign of a hill and it slows right down to a crawl. i have given up on it and am buying a new zbox engine. i dont think i will ever buy grubee again.
