    Someone replied to one of my posts about my carb and they said I should loosen up the carbon build up by spraying water in the carb while it's running to loosen up the carbon. Can you guys give me some details on how to do that? I don't want to screw it up /forums/images/icons/frown.gif .
    Thanks,

    Spray water with a spray bottle into the carb with one hand while keeping the engine running w/the other hand. Sort of "steam cleans " combustion chambers.

    I'd suggest going out and buying GM's "top engine cleaner" or whatever its called. From all accounts, it is amazing stuff.

    To be fair, I've never tried the water trick on a known dirty engine, but I did on a newly rebuilt one, just to see how it liked the water lol. Just took a spray bottle and started squirting. (on spray, not stream)

    Didn't seem to hurt nor help the motor, and didn't even seem like I was putting much in there, as the exhaust wasn't even really steaming. May have been condensing inside the pipes though.

    Try some stuff called Seafoam.... it's good stuff and you can even put it on there with the truck running....

    I did the seafoam trick. IT loosened the motor up. I was blowing stuff out the tail pipe for a while. The bad news was that I think I blew out everything that was holding the poor motor together. It died about amonth later /forums/images/icons/frown.gif

    After you use the engine cleaner, be sure to do an oil change to get it out, because the engine doesn't get lubed well with the cleaner in there.
