That is very low. Either the timing chain has stretched and jumped a tooth or that motor is just plain worn out. |

Did you open the throttle up all the way when you performed the compression test? I have seen numbers like that when someone forgot to open it all the way up. |

Check to see if you have spark, use instructions under "Magnetic Pick Up Trigger": http://www.msdignition.com/page.aspx?id=3206 |

Those comp numbers are still pretty low. Do you know the history behind the motor? Miles, cam, previous repair work done. |
