Flooding Carb #4

Hey Mad, well you have ruled out the wires and probably the plugs, that's a good thing. Now let's go back to the carb. Did you change the filter? I know that you have taken the float needles out but have you pulled the bowls to make sure there is no dirt in them that could be blocking the jets. this is not as difficult as you think. They are 4 bolts on each bowl (all 4 corners). Take out one of the bottom ones first. Have something that will catch about 6 oz. of gas that is going to drain out. Then pull the remaining bolts. There are fiber washers that may break apart most Auto Zones/Advance store have replacements. Pull the bowl straight off the housing. There is a gasket that may tear when you do this, again Advance/Auto Zone. If bowl sticks, do not pry apart. Tap it like a pickle jar lid. Blow out bowl with compressed air. Replace bowl and do the same with the other one. When installing bowls make sure that the accelerator pump handle does not get caught up. Don't force anything. Remove the jets using a small flat bladed screw driver. Blow them out. Check the movement of the floats. Call us with the results. peace Bud

yes I pulled the carb apart, cleaned it, shot some carb cleaner through just about everything, re-asembled and re-adjust the accelrater pumps.. still dont sound or run right...

here is a video clip of the spark I get from the wire to the alternater, it's about and inch to a inch and a half arc, I placed a screw driver in the plug and put it near the alternater. even though you can see a bright arc, I did this several times and the spark was bright white... I thought it should be blue, how does it ark so bright being white?

ok, here is a few video's I made. the first and 4th video tells the most.. I have an an msd adjustable advance, when starting the car I will advance it 4 degrees, once running I would normally put it back to it's original setting.. as you can see I am having trouble gettin it started, in video 4 it's fully warmed and the timing is set back to normal.. when I was having no problems the car would start the first crank, and Idle fine, even stone cold..
so let me add some info.. I noticed in the beginning of the summer the car was getting harder to start and idle when cold.. middle of summer it started to run on, when I would shut the car off.. the last 150 or so miles it's started to run rougher. how you see it running is the worse as of yet.. so it appears that there was a problem in the beginning and perhaps this is the sign of it's worse.. I think some of you can diagnose the problem, just by watching the movie, or least I hope so..

1. What kind of distributor do you have?

2. Does it have a vacuum advance can? If so, what's it connected to?

3. What is your base idle timing setting, and what's your curve (how much centrifugal advance, and when is it all in)?

4. No choke isn't helping any.

I dont know off hand, last time anything has been touched was probaly 3 years ago, the distributer I bought new on 90. no vacume advance, didn't know anything about them when I bought it, summit didn't fill me in, on the difference, it has gear drives, so there is no chain stretch.. previously this car ran awsome loads and loads of bottom end tq..

 

[madvette74]

like I said, the car use to start right up, idle fine, no hesitation, ran excellent, absoluley no complaints on startup, I doubt most cars would start up with ease as mine did, without having the choke. so I know the choke made no difference, at least in my application..

can't run the videos. Any suggestions?

 

[madvette74]

try and visit the site I uploaded video, you may have to install a player.

tried that site. no help. downloaded player 10. still won't work. can watch your drag race videos tho. mybe my puter messed up again.

 

[madvette74]

in the video of that race with my sons, that was the first time, I started having fuel problems. no fuel to secondaries. you see in the video it starts to spin, the car bogs down. and I just feather the gas to keep it from stalling..

 

[madvette74]

I should add, that my vacume gauge dropped from 12-14 to 10-12.
I noticed that when you click the clip it says servy over loaded, you may have to click the clip several times to get connected..

(NOTE: This is a completely worthless post by me... just having some fun!)

Solution to your problem: Put the factory Q-Jet back on it and you'll be just fine. It will be just as effective and likely much more efficient than your Holley DP'er.
