These carbs are not rocket science- - - - -if you can read an instruction sheet and make accurate measurements with a ruler or a pocket machinist's scale, there's no reason not to buy a repair kit and try a rebuild yourself. Just make sure all the air and fuel passages are completely clean and blow a lot of air through them with a high pressure nozzle from an air compressor. Then reassemble everything in accordance with the instructions in the kit and make the adjustments they recommend.
