First and foremost, I want to say that even though I work on cars, I have very minimal knowledge when it comes to the engine. However, I hope someone here will have some suggestions or things I can check on to get to the bottom of this issue. First the specifications: This is a 1976 Maverick with a 200 I-6 engine. The carburetor has a metal tag on it that reads: Motorcraft, D6BE, BB, A6A, 06. Then on the side of the carburetor is says: Mfg. by Carter for Motorcraft. I have a Chilton’s repair book, but the numbers I listed from the tag do not match anything I have read in that book. It mentions a Carter YF, a Carter RBS, and an Autolite (Motorcraft) 2100D for carburetors, so I’m not sure if the tag I’m looking at has the ID numbers on it. Anyway, here is what is happening with the car. When I first start the car, it’s running rough while idling, and it smells like its running rich. I took off the air cleaner and noticed the choke plate is fully closed. When the car was running, the choke plate is only open slightly. I played with arm that fastens to the choke plate and got it to open, started the car and it seemed better, but only for a short while. Then I took apart the automatic choke housing to take a peak, and saw it had a coil spring inside and did not want to screw that up, so I put it back together. After that I put the air cleaner back on and I took the car out for a drive to the local car wash; then it actually seemed to be running pretty well! But it was short lived, as on the way back home, it stalled when I slowed down to turn onto my road, and for the rest of the way I had to keep the car on pretty high RPM’s or it would stall. Once back into my driveway, I had a hard time keeping it from stalling as I got it back into the shed. I’m back where I started, it doesn’t want to idle, and it smells like it running way too rich. Where do I go from here? What do I need to check? Are there any instructions on how to check the automatic choke? Could the float be sticking, and how do I check that? Any suggestions I would greatly appreciate. Thanks! Art
I would recommend rebuilding the carb. If the car has "sat" at all by any previous owner....then it could use a rebuild. Pretty easy to do.
agree with Craig. Short turn help right now, the spring on the choke housing has to line up with the arm in the "linkage" When you look at it, the spring with heat rotates, moving the linkage of choke plate, opening up the choke. I think you put the cover back on and did not get line up right.
Yeah, I figured a carb kit would be a good idea regardless. Will the kit address the possible choke issues? I have never installed a carb kit, so I hope it has good instructions! Anything I need to "watch out" for? I'll assume I need to remove the entire carb, does the kit come with a new gasket for the carb itself? Hope these are not dumb questions.... Thanks again! Art
It could still be a Choke Thermostat (object with the coil spring) problem also check for a clogged or broken heat tube.
Yes....It will come with instructions. Be sure to use a carb cleaner and compressed air. You will need to let parts soak if they are really gummy and dirty. Clean out the choke passages real well as well. the instructions will tell you how to adjust the choke as well. Yes....you need to remove the carb from the car. The kit will come with all new gaskets.
When rebuilding it just take your time and take pictures and/or notes on how it all came apart. Keep track of all the little clips and screws. The I6 carbs are pretty easy to rebuild being just a single barrel. Once you rebuild one, you will have a better understanding of how it works and how to tune it. Good luck.
Hey thanks guys for the tips. I ordered the carb kit yesterday, should be in today. I also ordered a new float as well, just to be sure. I'll need to borrow a digital camera so I can "record" how everything is put together so I don't screw up. Hopefully this will take care of the problem.... Thanks! Art
Picked up the carb kit today! I took a look at the schematic and to tell you the truth, it kind of has me freaked out. Man, lots of tiny parts and I'm sure hundreds of way to get this thing put together the wrong way! Wish me luck, maybe it's not as bad as it looks. If I get a chance, perhaps I'll pull the carb tonight. Thanks everyone for the tips and help! Art
Thanks Craig, I may just have to take you up on that! I did not get a chance to pull the carb last night, and my schedule is booked for the rest of the week, so looks like it will be next week before I can get started. First things first, my daily driver (94 Buick Skylark) needs a new starter, so I'll be tackling that this weekend sometime. Art
