There is also a screw behind a hardened cap inside the casting. I used a carbide cutter and a punch to access it. I thought 1500s had Quadrajets. S10/15s had Varajets.

I have a 1986 GMC 1500 with a 5.0 and stock rochester carb. The truck will start but you must keep gassing it as it won't idle. It kicks off every time. Any suggestions on how to fix this cold natured


fast idle speed screw, works off the fast idle cam which the choke adjustment sets, it works together by linkages. This is the raised idle speed setting you need to keep a cold engine running. First you set the idle speed by the idle speed screw with engine at normal operating temperature. Then you set the linkage up so the cam is on a raised step, throttle will be held on that raised step. then you can turn the idle speed screw to get idle at about 1500-1800 rpm. Now when you start engine cold, choke will set the fast idle cam on that raised step- when engine starts and runs it should be running at your fast idle setting. That's how it supposed to work, you just have to get everything adjusted right. I hate carburetors, they never stay adjusted right. Considering their complexity and small mechanical parts, no wonder.

How do you set the idle


There are all kinds of adjustments on that vehicle. Also, it depends on which carburetor it is equipped with. That vehicle came with a Rochester 2-barrel carb, a Rochester Quadrajet carb, or a Holley 4- barrel carb. There is not enough time or space to post all of the information about this here. I would recommend going to alldatadiy.com and subscribing to the service information for your vehicle for a small annual fee, or purchacing a manual like Chilton or Haynes.

New rebilt carter yfa installed, but idle at 3k all adjustment screws backed out, ? the 2.5 L 4 cylinder came from P O with a jury rigged rochester carb of 77 ford vintage, hard to start so I got the...


The 2.5 L engine is the Pontiac Iron Duke sourced from GM since it was still AMC. They came with Rochester carbs, while Ford used Holley 2 brls on their 4 cyl engines and Chrysler used Carter carbs. You might have the wrong carb and the throttle plates are sticking on the intake manifold. You can try using a carb adapter/spacer. If you drive off road I would suggest buying a TBI throttle body injection system from a junkyard, and pick up a electirc fuel pump. Either new from a speed shop or used from a newer Jeep with a 2.5 L TBI engine, you'll need the computer, harness, relay, sending unit and lines as well. But you can pick up everything at a pick your part yard for cheap (some yards have all you can carry in your hands for $50 days).
