    quick question i did another compression test on my car today their all read between 110 and 120 so i dropped a little oil into the cylinders and the compression reading didint change .. a friend of mine said it could be the heads .... the electric choke quit on me a while back and i had been driving the car for about 3 weeks like that is it possible that with it running rich it built up so much carbon that the valves are not seating properly giving me a low reading all cylinders are reading the same and the new plugs i just put in have maybe 50 miles on them and already carbon fouled again ... or is this motor on its last rights? also do they make something i can pour into the motor to get that carbon out ? or does the heads need to come off?

    ummmm, if you have stock heads, thats about right. and the fact they are all within 10 of ea. other means you shouldnt worry about it.

    well the reason for all this is about how rich its running its terrible we put new carb on it new coil new points new condenser new cap new wires yet still smells terribly rich and its fouling plugs doesnt seem to be using oil but getting a bluish looking smoke untill you throttle it then its pure black

    I don't think you're going to find any product to up your static cylinder compression.

    There is, however, a product many swear by to remove carbon build-up, "SEA FOAM". You can pick it up at most autoparts stores.

    Be ready for the smoke show. :D

    as for a smoke show. get your self a big cup of water, and poor a bit down the carb. that'll turn your car into a mosquito abatement machine quick. just keep on da gas and add water as you see fit to fog out the neighbors. and its actually good for the mill, just vaporises the carbon.

    nope. try it, a bit at a time down the throat. actually will atomise the carbon. try it. anyway, back to your original issue, you did check all the things i p.m.d you about?

    Another way is to let a vacuum line that's going to the carb, siphon it (whatever "it" is) out of a container.

    I did this to my Volvo in a Car Quest parking lot with the Sea Foam. My first reaction was, "OMG! I've blown the darn-heck thing up!" :eek:

    I just knew the engine was going to keep smoking until a rebuild. Finally, after "the smoke cleared", all was fine.

    Ha! The expression on the faces of the onlookers was entertaining to say the least (I'm sure the look on my face was equally as entertaining).

    what plugs are you running? might just need a different heat range.
