Check the screw on the side of the carb in the middle, just under the slide and screw it counter clockwise.If this has no effect I suggest you check the cable adjusters to make sure you have free play on the cable.

please leave fair comment if I have helped you

thanks

SOURCE: just need the height setting for the floats the

YOU CAN ADJUST FLOATS WITHOUT SPECIAL TOOLS. ALL YOU NEED IS A FOOT LONG PIECE OF CLEAR TUBING, SIZED TO FIT THE BOWL DRAIN. SET FLOATS AS CLOSE TO WHAT THEY WERE WHEN YOU REPLACED IT. INSTALL THE BOWL AND PUT THE TUBE ON THE DRAIN. OPEN THE BOWL DRAIN SCREW WHILE HOLDING THE TUBE UP BESIDE THE CARB. WHEN YOU GET THE TUBE BESIDE THE CARB ASSY., THE GAS IN THE TUBE SHOWS YOU THE EXACT LEVEL OF FUEL IN THE BOWL. FROM THIS YOU CAN MAKE ANY ADJUSTMENTS NECESSARY FOR CORRECT LEVEL. THE LEVEL SHOULD BE RIGHT BELOW THE PLANE WHERE THE BOWL MEETS THE CARB BASE.

SOURCE: What is the float height on a yamaha pw80

The float bowl level is set in between running it dry at full loaded throttle and fuel overflowing from overflow hose. The floats have a small brass tab that bears on the needle, when it rises, it pushes needle into seat and restricts fuel. Set this tab level with rest of tab plate surrounds for the middle fuel level position. Bending tab down will let more fuel in, up for less.
Better to put up with a little fuel overflow when you lay it down than starving motor of fuel when you need power the most. Damage can result running too lean.

SOURCE: How do I tune up

Remove and thoroughly clean the exhaust and muffler of soot/carbon buildup, test/replace the spark plug, test/replace the coil/wire assembly, and ensure that the chain is at it's proper tension.

A full bike workup includes aligning the rear wheel, checking strut/shock damping pressure.

While the plug is out, if you have a compression test unit, or can get one, test the engine's compression. It helps over time to develop a chart of compression readings from each tuneup, when it comes time to properly diagnose engine problems.
