    Engine breaks up at high speed

    OMC 5.7L carbed. It has one of those big double fuel inlet holley carbs. About as soon as it hits 4000rpms the engine will start to break up and shake a bit. It will hit 4000 and kinda gradually loose a few hundred rpms but never stall and will maybe only drop down to 3500. I did a full...

    What thickness flax packing to use?

    Hey, I have done a bunch of flax packing in the past but never had to find out what size thickness to use. I have to do this for the first time because what came out of the packing nut was just like dust and I couldn't get the size from it. Is there anyway to find out what size to use? Thank you.
