I'm concerned that I'm missing out on half(or more) of the excellent knowledge out there.<br /><br />I need to know if I need to buy new pistons<br />but I should only really direct you to my topic in the merc forum.<br /> http://www.geocities.com/mercfix <br /><br />if you click on the thumbnails the images are large... dial up users beware.<br /><br />Sorry that this is kind of a double post. But it's supposed to be about encouraging (well begging really) the experts to review topics outside of their specialty.
