Simplify a Motorcraft 2150
#16
I must be a masochist..because I finished rebuilding the carb and installed it. Starts and idles smooth and it's very snappy from idle to 3000 rpm. It is much more responsive than the larger Edelbrock I had prior and much easier to rebuild. I need to check the plugs and may swap the main jets to a different size. The only bumps I encountered were very minor and remedied pretty easily. One air mixture screw was seized but came out with some diligence. The fuel needle seat didn't seal to carb body on the initial install, so I removed the seat and replaced the seal with the old one and all was well. I did have to shorten the throttle linkage to allow the proper range. I have an oil bath air cleaner that I'm switching over to a paper element that'll finish out this little project.

That's great! I thought if you did run into issues it may be the booster clusters that came installed in the carburetor being completely wrong for the jettting and the engine. But its running good it's probably not an issue. The other challenge may be the setting of the float when the engine is warm. But if it starts good after a good heat soak it's also probably OK. Glad to hear it turned out well!

I think this will close out this thread for me. Other than minor tweaks I don't foresee anything ground breaking in simplifying a 2150. I installed a second return spring, a manual choke kit, and finished converting an oil bath air cleaner to paper element. It starts quick, idles nice, and runs well overall.
The fourth Saturday of every month there is a cruise in to Main Street in downtown Jacksonville, FL. A bunch of people bring out all kinds of rides and congregate on five or six blocks of the Springfield historic area of main street. Bagged frame dragging dually trucks, lifted 40"+ tire 4x4's, rat rods, vintage hot rods, modern muscle, mid 60's muscle, Model A's and T's, wide, wide variety of cool cars and trucks.
Only picture I took of the night, parked at Krystal with Kirby-Smith Middle School in the background. Happy to be getting out and enjoying the truck.

Technically the jetting looks a tad rich, if you can believe that. Idle time will definitely blacken the base ring though, and skew the indication. That may be the case here? That's why a throttle chop while on a highway run is recommended. Look way down in the plug, where it transitions to the shell, for the "fire ring". That's wide open throttle mixture indication. Maybe you know this already. Wideband O2 sensors are real interesting to work with. Ignition scopes too. And the good ole' vacuum gauge.

That looks exceptionally lean to me. On the plus side, you must not be burning any oil! Reading plugs with modern fuels is pretty tough, on EFI engines fuggedaboutit.
Do you know if the engine has hardened valve seats? If it doesn't I'd rather be on the rich side, gas is cheaper than valves.

Ha Ha Ha. That’s so funny but true. I saw that picture and first thing came to my mind was to throw it into the scrap bin. It’s shot!!!

To update the thread on the 2150, it's the same as I bolted it on a little over four years and 4000 miles ago. I keep telling myself to grab a Wide-band Air/Fuel Gauge and spend some time really tuning it but I haven't gotten to it yet. Mileage seems to hover around 10-11mpg and I think it could be improved quite a bit.
