Robin for model number tb25cs
Hello, Thank you for your question. 2 stroke engine fuel systems require regular maintenance because they sit for long periods of time between use and the oil in the fuel gums up everything. First, make sure the spark plug is clean and you can use fine sandpaper of 180 grit or finer to clean it gently and make sure the air cleaner is free of debris then try. If the problem persists then dump the fuel and create a fresh batch to the proper ratio. Clean out the entire fuel system, you may want to clean the carburetor and it is probably best to remove it and rebuild it cleaning out all the internal parts then reinstall. If there is any corrosion inside the carburetor it will need to be replaced. Once you have it reinstalled you will need to set it up. 2 stroke carb set up generic instructions which cover most. There will be 2 idle screws. One will be idle mix and the other will be high speed. Turn both screws in to shut off fuel then back off 2 turns, next start engine, it may not run great by should start at these settings, Start the motor, and let it run for a few minutes to warm it up. You may have to fiddle with the throttle a bit to keep it running. Slowly turn in the low-speed jet, until it starts to die, then back it out another 1/4 to 1/2 turn. Next, hold the throttle wide open, and slowly turn in the high speed, until it really starts to smooth out and rev high, and start screaming, then back this out until it starts to run rough or slow down, and then turn it back to the midway point between these two positions. Keep playing with the low-speed needle until you get rapid immediate response from the throttle and good idle with the idle adjustment. Then play with the high-speed needle, but always back it out from the setting about 1/4 turn or so, from where it runs the smoothest. This setting of backing it out will allow more fuel when under a load and keep your 2-cycle motor from running too lean. Put a load on it and just tweak the settings just a hair at a time. If you're in the ballpark it won't take much adjustment to make a difference. I hope this helps and good luck with your repair.
