    HELP...Engine Burning Very Rich... Any Ideas??

    in Engine Tech

    Posted

    Thanks you all for the advise... I appreciate all the feedback....

     

    And Yes Sam actually its both..... I am actually seeing some light black smoke from the exhaust when im out on the interstate.. I really dont know too much about the timing and all so I cant really offer much insight on that.. I know I've had it checked several times by my mechanic and he swears its right...

     

    Ive been thinking about a few things..... and Im gonna feel so stupid if this is my problem.....

     

    I do have an eddelebrock 600 cfm carb with the manual choke... But I never got around to installing the choke cable... so right now I have nothing hooked to the choke linkage at all.... on a cold day I would just pop the hood and push the choke linkage with my finger... Is it possible that after the engine warms up to normal operating temp and as im driving it... the suction from the carb could partially be closing the choke flapper causing it to run rich?

    Hey... thanks for the quick response Mo!! But yea... I read about that on the edelbrock website.... Im sorry!! I totally forgot to mention earlier to you all that I just added a feul pressure guage and regulator last week... and its still doing the same thing.. I dialed it down to around 4psi.. Seemed to be a tad better but basically still doing the same thing.. Where is the correct place to check my pressure on the feul line?? Before or after the feul filter?

    It runs good at a cold start while idleing ...No raw gas smell or nothing... but when I take it up the road and get it warmed up good to a normal operating temperature (190 Degrees) I get a sluggish idle and a strong gas smell from the exhaust like it wants to flood... And sometimes it's hard to start.. And when it does I get Black smoke....

    I've taken the carb off several times and checked the needle seats float levels to specs and gave it a good cleaning...it will do good for a minute but then back to the same thing

    like I mentioned before ...If this helps... It happens only when the engine warms up to normal temp ...And sometimes I can hear gas dripping into the carb when i shut it off.

     

    Im dont know much about tuning carbs and etc. But any help would be greatly appreciated..

     

    Thanks!!
