Hello all, thanks for the opportunity. I will be workimg on a 70CT for a friend, its got a different carb and manifold, carb is from a honda twin, either 160cc or 175cc marked "680A" as seen in the pics. I dont know yet if the jets or clogged but my buddy has said things which lead me to believe it may be jetter too fat. He pulled out the main, which he said says "100" but this may or may not be accurate. Nevertheless, any idea what would be acceptable jetting for sound performance and dependability on a stock low mile 1970 CT with this carb? Thank you.
