When i crank up the car, my secondary's get flooded and the car dosent start, then when i finally get it started the secondary's open perfectly. Then the car run's perfect, but whenever i get to highway speeds and the car gets heated up, when the revs come down again the car, start's kinda like sputtering and wanting to turn of and i have now idea why it's happening, does anyone know what could be wrong? i need help

 

Did this just start suddenly? Have you made any recent repairs/changes? When is begins studdering, is there any smoke from the exhaust?

Before trying to start the car, look down into the carb and see if the secondaries are closed, or open...

 

your floats might be sticking,or your one way valve on the return side might be bad causing too much fuel press to build in the carb.. try leaving your gas cap off and try starting it like that, let us know what happens

 

i had been starting it without the gas cap because it did not have one and it's doing it. Yea i rebuilt the carb.

 

Did you reconnect the float bowl vent solenoid?

 

ahh good suggestion! i forgot about that one.. check to make sure its getting +12v when the igniion is on too

 

sry guys, but were is that solenoid located? And today i was working on it and by mistake took of a plug and the secondaries stopped flooding, but now it just cranks and dosent even make an effort to start.

 

its on the driver side below the fuel inlet/ return .. its a round thingy with a wire comming off of it

 

yea it's connected

 

Tap hard on top of each side of the carburetor (over the float bowls) with the plastic handle of a screwdriver. The needles are not seating most likely because they need to be broken in a bit.
The tabs on the floats against the spring loaded pins, the corners of the needle shanks against the brass needle seats; these all need to grind a little before they work smoothly. Unfortunately when the bowls are flooded, the needles don't go up and down enough to do this right away. But once they get seated, you shouldn't have any more problems.

-I'm assuming you didn't mess with your float levels by bending tabs, right?

 

i did and i know the float levels are correct because i rebuilt the carb and they were totally out of level, so i put them to the correct lenght and height. But thank guy's i finally got it, the secondary's were getting flooded because a vaccum hose was plugged and it was creating preassure, but then it didnot start so afdter long hour's of trying to figure it out, we finally saw that the spark plug's were loose and full of oil because it was running to rich, so now it's running good guy's so thank for the help.

 

Congratulations, it's all kick-*** from here on out. Enjoy.

 

thanx man, i will, i took it for a 50 mile endurance, speeding down the highway around 100mph to see if any problems came up, but it was all good, thanx for everything
