Ok so I rebuilt my carb today because the of me sucking in a bunch of muddy water. But, now I can't seem to get my truck to run right, it keeps detonating like crazy, and there is nothing I can do to stop it. It won't stay running unless I am on the gas. Also I retarded my timing because I thought that might be the issue but it did nothing to help. I also played with the float level and the idle screws but the only a slight difference when I raised the floats. I'm a little lost, why is it detonating like this? BTW: The carb is a Holley 4160 600cfm that can have my engine run as smooth as glass. But i guess not anymore.
