I came across a post awhile ago, but can't find it now. I would like to swap carb on my 300 and put a round slide on. What size? And jetting? Would these also be the same for a 340? Thanks
i believe the 340 used the same carb. I would say measure the inside of your existing carb and that would be your max size. You could probily go down one size from that as I believe the round sildes flow better than the flatslides. As for jetting hopefully someone will chime in as I have only done this with the 250 single.
