OK the question in hand now is Where are U located ( what country) ? just asking because I have never gave or had anyone give me comp #'s in BAR readings and I have done a zillion comp tests plus look at a zillion from others.

check carb and possible complete carb overhaul and new floats. what did your spark plugs look like ??? carboned up or oil somewhat fouedl or black or good ? What was or is your fuel pressure readings ? have you replace the mech fuel pump as of late ? Possible too much fuel pressure. Just throwing out ideas.

sorry, from germany.

The spark plugs are colored black to brown. but more black then brown. A repair kit for the Quadrajet is already on my desk. i wasn't check the fuel pressure so far. can do that next time. Wasn't also changing the fuel pump. it is a original OMC. Was thinking of to buy a red Edelbrock Fuelpump. But with the new spark plugs and wire the engine sounds much different to with the old stuff. i mean it sound more like a big V8. Sounds really good. :-)

So i will check Fuel pressure and overhaul the Carb + changing all the fuel lines and filters next time.

Thanks for your Help! Sorry for my bad english.

Definitely rebuild the quadrajet, they don't like to sit at all. It's a very easy rebuild, just make sure to get all of the passages and orifices perfectly clean. Once you do get everything going, be very very very gentle with the OMC stuff, especially an old electric shift stringer drive, like you have. Instead of it's original meaning, the new words for the OMC acronym are Obsolete Marine Company as parts are either expensive or impossible to find.
