weber problem. floats too high?

Shut engine off and look in throats of Driver side carbs. Is fuel dripping onto the throttle plates. While running, are they drawing the same amouint of air (as the pass side?) Are they syncronized?

Pull the top of the carb and measure the float level. That way you will know for sure. Do you have one of the Gene Berg float tools? It only takes a couple of minutes to check them.

+1.

How long since the carbs were last synchronised?

Things to check: absolutely ZERO slop in the linkage, float levels are correct, all cylinders draw the same volume of air, all mixture screws are out at 3/4 turn.

all are synched perfectly.

I dont see dripping. But when the motor cools fuel does drip after a bit into them.

I did buy the Gene berg gauge. I have not tried it yet. I thought i had to take the carbs off and flip them upside down. I believe i had a major fuel pressure problem before and i am wondering if the excessive fuel pressure could have knocked them out of adjustment.

so basically you guys think fuel must be getting in on that side of the engine some how?

Does your fuel line come up to the drivers side carbs then around to the passenger side?

If so, I'd bet some "junk" has found it's way into the needle and seats. Very common with new installations.

[qsl]

yes it does... How would i clear that out?

Also check the brass floats for leaks.
They could be fuel logged.
Remove them and shake them in your hand and listen for sloshing fuel inside.
If you feel fuel inside the floats that means you've got a leaker.
Some where in the solder between the two brass halves fuel has gotten in.
This fuel inside the float will throw the weight of the float out of spec and in turn throw your float bowl fuel heights out of spec as well.

Ok, take the lids off all carbs one at time starting at the "1st" carb.

Take the needle out, flush the inlet out with compressed out air, measure fuel level as is in the bowl, measure the float weight, measure the float height and needle and seat for fuel level.

If you find the cause, reassemble and move onto the next carb.
