    Gordon replied to the thread Software in the cloud.
    With all of this discussion about Linux I will have to get back to trying it. I tried to use it a while back because I have a Dell...

    Gordon replied to the thread Exhaust valve timing.

    With my engine getting fuel to the combustion chamber was not the problem. Flooding was the problem. I turned the engine over via...

    I would be inclined to think that the spring tension on the intake valve would be too high, not too low. When you turn the engine over...
