OK, so yesterday I got a small pile of 1.08 Mtr crft carbs. I was looking for some to replace the Carter 2 Bbl's on my 258's and stumbled on a deal. Problem is, every one is missing some pieces and they are not all exactly alike, other than the "1.08" on the housing. Do all of the basic components interchage with other Mtrcrt 2 bbl's (1.14, 1.21, etc...)? On some there is the a component on top near the airhorn which is help on with three small hex screws hooked up to the Choke butterflies witha small linkage. On others it is not there. WHich is preferable... with or without? WHat is that thing? (When I rebuilt the 1.14 on my Commando, there was nothing under that but a diaghragm, though it did not seem to go anywhere and was not included in the rebuild kit) Does anyone have any guidance as to experience with the optimal jet and power valve specs? I know a loit of people have run them and maybe your experiences can benefit the rest of us! THanks and have a great week, Jesse __________________________________________________ Do You Yahoo!?
