Thats what I question too, how can you know the exhaust valve is burnt? Unless it is apart there is no way to be sure. Head is off...its burnt |

Just because you lost compression does not mean the valve is burnt. To say it is burnt you actually have to take the head off and look at it. It could just be that the EXHAUST valve is tight an needs to be adjusted and is staying a little open therefore loss of compression. So first check the valve adjustment and adjust the Valves: for 50cc INTAKE .003 inchs and .004inchs EXHAUST for a 150+cc INTAKE .004 inchs and EXHAUST .005 inchs. THEN CHECK your compression again. Alleyoop Head is off...and its burnt |

Backing the A/F screw out adds fuel to the low speed circuit. I really doubt that burned up your exhaust valve. The main jet is what makes it run lean or rich. Also adjusting the needle up or down can affect that. How do you know it's burnt, are you able to visually inspect it. If you had a leak at the exhaust port that was letting air to get to the valve it can warp it and boom...compression loss. What was your compression on the dial by the way? Checked compression..it was 30...took apart...definetly burnt....no exhaust leak. |

Lost compression..did a compression test. Exhaust valve is burnt. What do you thik I should check?....When adjusting fuel/air mixture screw....does turning it in give it more air or more gas? Before I replace valve do you think I should up the jet some? Spark plug didn't look all that bad color wise. Thanks for any input!

What would make a new stator go bad? I had very weak spark...traced it down to the stator. I put a new stator in and was getting really good spark for a few days..and now getting nothing. I am getting around 49 volts at the red and black wire coming from the stator. I never was getting up to the 85 volts like I read on other posts what I should be getting. I did voltage tests at other spots and all seemed fine...I even swapped cdi's and coils and a new flywheel and still nothing. Any idea's would be greatly appreciated! I have a feeling I got a bad stator ...only because I never did get the voltage I should have. Do ya think it might have took a crap?
