First, check the bore sizes and see if they're the same. It should be a number ( 1-1/4, 1-5/16) cast in the front of them. If they are the same size bore, then you'll have to deal with the jets (orfices). If they're not the same orfices, you'll have to change 'um. If you've never changed orfices before, a manual is a must.<br /><br />c/6<br /><br />Hooty
