One more question.... I have trouble with the car stalling going around a turn when the engine is warm. Only turns and only warm. I have replaced the carb and the fuel pump. Might it be soething else? Or might this carb be defective also?

3/14/2000<BR>You failed to mention whether you have a six or an eight. In addition good to know if it is an automatic or standard transmission.<P>Did you take your original carb apart to check on proper float level? Look for proper placement of ignition wires, also look and see if wire leading away from negative side of coil is in tack. This wire had a tendacy to wear away. Another good source is gas line. While you are checking all of this make certain that your gas tank is full and that your gas cap is vented. A vacume cold also stall you out.<P>Good luck.<BR>Frank at <fwollman99@yahoo.com><BR>

This identical problem was reviewed in some publication (possible earlier on the DF) I read recently and the solution presented there was very interesting. Check the hold down bolts on the carb. In that case the bolts had worked loose enough so that while making a turn the carb "rocks" slightly and air was sucked thus changing the mixture just enough to cause the engine to stall. Worth checking.

Ok I'll check it but I doubt it .... I dont think I would have put on 2 carbs and not tightened both of them down enough ... but who knows.

It is an 8cyl and a three speed. It doesnt stall when the clutch is engaged or if I leave my foot on the gas. I had checked teh original carb and asjusted the float to the proper level and adjusted it many more times to see if it would change anything. The gas lines seem to be ok... I dont see any crimps. Fuel tank is always filled up... the car is driven about 300 miles or so per week so it is regularly filled. The gas line from the fuel pump to the carb is new, the carb was also replaced... I had a spare NOS sitting around so I figured It wouldnt hurt to try. Also the flexible gas line from the pump to the steel gas line ins new. I haven't checked the wire leading from the negative side on the coil. I will do that. Well. Thank you. Let me know if I left anything out.<BR> <A HREF="http://home.talkcity.com/ferraridr/pontiac51" TARGET=_blank>http://home.talkcity.com/ferraridr/pontiac51</A>

51,<P>The hold down bolt posting was for a 1962 Starfire (I was the one who had the problem with an early 1960 Falcon). I used to have a 51 Pontiac 8 and I remember it also has a very heavy air cleaner for it's carb, so that may be the problem (check especially to see if the studs/holes are stripped which would allow them to loosen quickly after the second carb installation). <P>If not, you could have the same symptoms from a loose manifold on a straight 8 (or 4 or 6). Anything that causes sideways momentum to open up a vaccuum leak could be the culprit.<P>Good luck.
