I have a BME 44 which until recently ran fine. I had to replace the hall sensor and while I was at it I installed a new bosch plug cap from CH. I went to start it today, and found that while it idles fine, once the Tx stick moves up the engine speed only increases a little bit and then stays pretty static. Every once and a while it will surge a little bit like it's trying to go to full throttle, but it doesn't. The throttle linkage is moving fine, and so is the butterfly, so I'm assuming its the gas system somehow, and probably has something to do with the high speed needle. Any ideas out there? I'm not very experienced with gas engine problems, because up till now the ones I've had worked great. Any assistance would be appreciated.
Thanks
