dosent ping or anything at 10, seems to work fine, fuel pump wasnt working properly, fuel filter wont fill with fuel so i took it apart, gave it a clean and now works a bit better than it did, still not filling with fuel. needs to be replaced. no prob getting to 110 on straight roads but as soon as there is a hill it drops to 6o with pedal to the floor. replaced exhaust and cylinders range from 140-150, not sure where to go with the power loss uphill issue though, could it be fuel tank needing a clean?
