those are pretty much the easiest carbs on the planet to rebuild. 9 times out of 10 you can take it apart, clean it out and get it running tits without even buying a kit. some carb cleaner and compressed air goes a long way. the float setting is all you really need to know other than basic skills. if youre dumping gas , there's **** stuck between one of the needles and seat , a hole in a float , or float level is all out of wack. as mentioned they like between 5 -5.5 lbs of pressure. I've never had a stock pump push fuel past a float bowl valve.
