Short answer, No. I did just rebuild a carb on a Ryobi blower but no where near as complicated as this set. I picked up two Mikuni carb kits from Bay Area Powersports. I had to return the aftermarket set to them and just exchanged for this SET that includes genuine Mikuni kits, needles and seat.Have you ever rebuilt a carb?
For your carbs get MIKUNI kits ONLY. Go one at a time. Carb 1 and carb 2 are different. So one at a time mark and then slowly turn in both your high and low screws. Record how many turns on each. It may be 1/2, or 5/8 of a turn. Or could be 1.5. I mark the carb body on the edge of the screw hole with a small sharp chisel and very lite tap of hammer. Then disassemble with camera Pics for reference. And let soak in the carb cleaner.(a gallon can pre purchased from auto parts store) I know Napa carries carb cleaner in cans. I'm sure most the others do to. Soak it over night works best agitation once in a while helps but not to hard. Then rinse with hose and blow dry with air if you have it. Then use carb cleaner spray to spray through every office you see. Then follow the drilled return mod under "how to's" and clean again with spray cleaner and reassemble. Reuse your old needle/seat spring.
