Hi. Don't know. Did not get a rebuild kit.....big mistake. Carb had been 'worked on' before. The seals had some kind of sealer on them and the slide was drilled. So, I had to buy a new slide and a rebuild kit. After talking with a carb guy I learned the slide being drilled was part of the previous Dyno-jet kit installation. Also, drained the tank of the old gas and have 2 gal of 93 ready to go in whenever I get everything finally done. Thanks for asking.
