im really having problems. my jag 350 fa will only run if i spray ether in the carb. the fuel system is spotless. it also revs really high, and even if i stick my hand over carb it will barely run. I know its getting fuel. I just put a new mag side piston in, and pto seal. the mag side seal has to be bad too right? i didnt get a chance to look at it. the mag side cylinder was burned, so the mag seal has to be blown, or is this just a coincidence? I have 120 on pto and 110 on mag(piston is new rings still prolly need to seat, and the cylinder had a little scoring but it runs). PLEASE I NEED SOME IMPUT ITS DRIVING ME NUTS! thnks
