Re: 6HP Fisherman...need help with cam follower adjustment and tiller/throttle settin
seems like the brp carb kit contains a new float as well...pinion is relatively cheap and just need to drive out the roll pin to replace...concerning special passageways in the carb, look at the exterior casting on the port side of the carb body. This allows fuel flow up to the idle circuit. That passage, the mixture needle passage, and the 3 or 4 small holes that exit into the back of the carb throat behind the throttle plate all need to be clean. Pop out the core plug on top of carb, just follow the idle mixture needle passage and it's at the end of it, clean that area and the small idle circuit holes. New plug goes in with the convex side up and is seated by expanding it. I use a 1/4" extension, socket end, and tap it with a hammer, but whatever does the job will work.
Plenty of posts on carb cleaning...starting point for idle mixture needle is 1 1/2 turns out from a gently seat. If everything is up to snuff with those 6 hp's they'll idle real smoothly at very low rpm.
