My b450 starts and is idling perfectly; but when I apply the throttle for some reason the power is not transferred to the head of the trimmer..any ideas?

My b450 brush cutter won't start, check for spark on the spark plug, there is spark, tried using starter fluid, still won't start. what do I do next?

Pull up the choke .if u already did that...place a few drops of mixed gas in the chamber and pull the starter and if it starts then the carb needs clealing or the diaphragm needs changing. If it didn't start the the coil could be weak or the engine is problematic

I have a shindaiwa B450 bushcutter and my nephew put an oil rich fuel mix. (He didn't add the proper fuel to the can for the correct mixture). The bushcutter has since lost all power, meaning it will start, but the whip barley turns and it sounds like there is no power in the machine. Its much quieter now. Is this normal?

Empty the fuel tank & replace with a small quantity of straight unleaded. Set to full choke, full throttle, & try starting it. When it fires up, stop it immediately, empty the tank & refill with correct fuel mixture (25:1).

I've also found that starting at near full throttle, with prompt choke adjustment once it kicks in, helps when starting.

BTW, not pointing the finger at anyone, but if they say that the B450 is fragile, they're profoundly delusional. I bought mine secondhand on eBay, it was ex-council, so extensively used, I've had it for 7 years, clean the filter occasionally, never cleaned or changed the plug, & it hasn't missed a beat.

Thank You, for the feed back. It worked like a charm. Cleaned the carbon out and runs great. For a 15+ yo bush cutter it runs like new
