I have a strange issue going on and maybe some of you guys might be able to shine some light on what might be taking place. First off, I own a 300 MXU and a 90 Mongoose. My kids and I ride pretty often on some trails near our house. I am brand new to the ATV world so I am learning about the mechanical side as I go. I have had zero issues up until now.
A couple of days ago a strange issue started. I cranked up my 300 up and took off. Now, usually I let it warm up for a bit. Well, my dog took off and chased a rabbit and he wasn't slowing down so I decided to hop on the 4-wheeler and go get him. As I went down the drive way, it died. After that, I had a problem getting it to start. I would grab the left brake handle, push the starter button and it would make the starter/injector sound but wouldn't turn over. I kept trying and about 5 minutes later it finally it started. I started to take off and EVERY time I squeezed the brake handles (even with the motor running) it made that same starter/injector sound you hear when you press the starter button.
I went out and crank it up again today. It starts without any issues but as soon as I squeeze EITHER brake handle I hear that sound like it is starting/injecting fuel into the carburetor (even with the motor running). If anyone has any advice or has come across this issue in the past, please let me know. I plan on taking to the dealer I bought it at but if this is something I might be able to fix on my own I would like to do it. I am looking for any feedback from you experts and I am learning slowly..
Thanks, guys.
