Rcs4246b second season no problem last year
R U sure your running the correct fuel/oil mix ?
Testimonial: "Did replace the old fuel which helped also air filter needed changing out thanks"
SOURCE: stalls under load
Try opening up the high speed jet, see if it does any better. Turn it just a quarter turn at a time, if opening it up doesn't do anything, try closing it. If that doesn't do it, try closing it down all the way, then open it up 1 1/2 turns, this will put you into run mode, you can adjust it from there. You have 2 screws on the side of the carb, low, high, they are marked, don't be afraid to turn, that is what they are for. Check it out.

Check the air cleaner and muffler for plugging. One screw adjusts the idle stop (idle speed) position and the H and L jet screws set fuel mixture for high speed and idle speed mixture respectively. Turn both jet screws CW to stops (lightly) then back each out CCW 1-1/2 turns. This is a basic setting and should allow the engine to start and run. Start the engine and allow to warm up. Pull the throttle full on and adjust H CW until the engine starts to speed up, but 4-strokes. Correct adjustment is when the engine 4--strokes running free, but immediately 2-strokes when cutting. Release the throttle and adjust L needle CW until the engine idles fairly well, but allows the engine to 'follow the throttle'. Adjust the idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!

Sounds like its starving of fuel, start by replacing the fuel filter in the tank, if no better richen up the H screw on the carb by 1/8 turn out and try again.
