Hello I am looking for instructions on cleaning my carburetor. My slow speed needle valve adjustment does seemingly nothing at both low and high RPM, and the high speed adjustment seems overly sensitive. The whole thing has a hard time getting down to shifting RPM without quitting and my feeling is that the slow speed valve is clogged or damaged. I made another post about this but it has become focused on other issues I am having with the motor. Thanks for any links or advice anyone can provide. I'm new to this so forgive my lack of knowledge

Buy a real carb rebuild kit, with all new gaskets, needle and seats, and it will also give all settings to reassemble to factory specs. Due to age, fuel lines will also need replaced even those little short pieces. Lots of videos on rebuilding these popular carbs. Find a factory service manual or look one up for reprint..
