Bogg....GOOOOO!! Carb. issues.


Recommended Posts

Posted

This B&B is trying my patience. I have torn it down, soaked all the pieces in ATF for days, cleaned cleaned cleaned, re-assembled with new kit/valve and soldered float (cracked) Now it starts and idles fine and even runs down the road well, nice response not too rich, all good EXEPT} When taking off from stopped you cannot stomp it or it will die, in fact, it is necessary to give it gas (clutch disengaged) Bog down, keeping peddle down until it revs out of the bogg, then you can drop the clutch and take off, hell, you can even skin the drives at that point. I was planning on two carters on an offy intake but now I am thinking of going with a stromberg. Anyone have any ideas, guesses or stories?? I thought maybe the vacuum advance but I recently installed a brand new HEI unit from Langdons' (tested advance w/ vac. pump....good)

Did you soak the accelerator pump leather in oil prior to installing it?

With the air filter removed and the engine off use a flashlight to look down the throat of the carburetor while you open the butterfly rapidly. You should see a stream of gas each time you open the butterfly. If you do not then your accelerator pump is not working. Soak the leather plunger in oil overnight and that should fix the problem.

While youar cking things, make sure both check valve balls are present in their places within the acc pump circuit. Alo make sure the linkage is attached and functioning.
