Sometimes when rebuilding these carbs you need to be careful using compressed air.   Too high of pressure can mess up the check valves.

I read on here about using a 620 ign.coil  on a 600p to get rid of the rev limiter .will a 620 p carb  work on a 600p ?

620p carb is a direct bolt on and should be an improvement over stock. IIRC it is something like a 1mm larger venturi than the 590/600 carb.


coil is also a direct bolt on
5105H and 6400H in stock

cs-600p carb has the pass through - semi fixed jet in the metering chamber.  If the check valve in that jet is bad, Echo wants you to buy a new carb.  The workaround is the Husky HDA-199 uses the same semi fixed jet, and walbro sells it through their parts distribution system.

86-578-1 Nozzle Assembly

The repair procedure is to strip the carb down, warm up the casting and press the bad jet into the throttle bore.  Use a light hammer and a 1/8 punch.  Tap the new jet in from the metering chamber while the casting is warm.       

For tuning its best to keep the engine under a load and off the rpm limiter to set the high side.  Otherwise, use a tach.
