Alright so I recently bought a 76 Maverick 2dr with a 250 in it. I have said in previous posts the issues but just to reaffirm and inform anyone who hasnt read my posts previously I will say what I know again. First off, bought the car rough running, acting like it was starving for gas and continuously dying. I let it set for about a week without any action - mainly because I was busy. Brought my battery in out of the cold, charged it up and threw it back in yesterday. Car starts up no issues but still runs rough. I decided to take off the carb and redo it with a rebuild kit which my uncle suggested. I'm pretty new to this car thing so bear with me if I say something stupid :16suspect First off I need to know what specific rebuild kit I need to buy for this carb. Like I said carb is off my 76 maverick which is a 250 auto. Secondly, I was curious about something. There were 3 distinct things I noticed when removing the carb which I was unsure of - meening I was thinking they could of been contributing to this *starving for fuel* quality my car seems to have. 1. Is there supposed to be any sort of gasket where the carb connects to the engine? This one was lacking one... 2. The bolts weren't completely tightened down and it took very little effort to remove the carb - probably could of done it with my fingers from the git go. 3. There was a little cable (not sure of specific name) that was preventing the 'flap' (once again dont know name) from closing all the way at the top of the carb. Not sure if that matters or not. You can see in picture 5 what I meen, this was taken with the car off and this 'flap' still open. Does that matter? I'm trying to include pictures of the carb which the previous owner had purchased from a junkyard and installed - more than likely incorrectly. He didn't even know that the engine was a 250, he thought it was a 200... Lastly, is it ok, as shown in pictures, for these 'extra' hoses to be capped with bolts? Why aren't they connected to anything and just plugged off? Like I said, this is my first time doing anything like this and I am very very green. So any info and input is greatly appreciated. Local autostores are: Advanced auto parts Autozone Oreilly's Auto Parts How do I know if one of them has the rebuild kit i need?
Someone will come along with more help than me but I just wanted to confirm something. Did he give you the original carb? I would rebuild that one. If he took this one off a different type car or truck when you try to get parts it will complicate things. Yes, there should be a gasket between the carb and the manifold. Yes, the carb should be tightned down snug. Definately not finger tight but you don't have to tighten them crazy tight either. The hoses, it looks like the little one was a vacume hose. Is/was there a hose that comes from your distributor to the carb? Someone else may chime in and confirm whether there should be an vacuum advance. I used to have the 200 in a couple mavs but it has been over 20 years since I have messed with them. I currently have a V8 mav.
I have recently rebuilt my carb and i went to autozone for the rebuild kit just had to tell them the model and all but that wont work unless it is the original carb lit tony mentioned. If not most carbs that i know of have a model number on them that you need to find and then just give the store that and they shouldn't have a problem. As for the hose i agree that it is most likely a vacuum hose. When i rebuilt my carb the hardest part was just getting the old parts off because their isn't a very easy way to grab them. I had to use a chisel and kind of hammer it in to get some parts off. Make sure you keep all the old parts in case the kit for some reason doesn't have all the parts. I was having the same problem as it sounds like you are and after carb was fixed and tuned it runs great.
Instead of spending money on a carb you don't know what it came off of, get a rebuilt carb for your year and engine. Even if it's the correct one, at least then all you do is bolt it on and fine tune it if needed. Some of us have hose diagrams and can try to help you get the hoses hooked where they go or at least suggest what to do with it/them. Some hoses can be pluged, just need to get into it a little deeper once the (correct if not) carb is back on. Pics are a little dark too.
I can't really help you that much on ur carb issues (well maybe when someone chimes in with more info...), but don't worry about saying something stupid. I'm king on that one and it would take more than a carb question to dethrone me! The people on here are very helpful! Good Luck!
Where might I find a rebuilt carb which would seemingly simplify this process and my life and about how much would it cost? The previous owner did not include the origional carb, he probably tossed it :16suspect thanks for all of the input otherwise guys.
Rockauto has a carb for ur car for $133 after the $30 core. Pretty sure you can find better tho.. don't know how much of a rush u're in.
Not really a rush - plenty of snow still on the ground here and junky wheels + tires on the Mav at this moment so it wont be driven for awhile. Do you think these are stocked at local autopart merchants?
Since I posted that suggestion I looked up a carb at OReiley. It seemed a little expensive at around $200. The carb comes with a choke, I assume it would be new. There may be a cheaper unit out there just gotta look for it. I have seen them on Ebay before, I have a 75 250 so I kinda keep my eyes open for different things. I have rebuilt many carbs and would try and do it myself. Just that sometimes a bolt on is quick and puts the mind at ease to know it should be the correct unit. No chemicles and tiny parts etc to deal with. I gotten lazy in my old age lol.
Is that not the stock carb that is on there? I am new to Mavericks and 6 cylinders but that looks pretty stock too me. Usually the heat stove pipe would be long gone if if wasn't a stock type carb in my thinking. I am just thinking that in the only picture I can really see anything it looks like most of the stock stuff is there and I didn't read where anybody said it wasn't stock. If it's stock buy a rebuild and try your luck at it. clint
It could be correct. In his post he said it is from a jy and the guy thought the motor was a 200. The carb could be just fine except was installed with a bad or missing gaskett. A poster above said a carb at rock auto is like 133. Definitly worth considering, but then it's a time thing with shipping... and if something is foul? Pros and cons to saving a hundred bucks AGHHH!
rockauto also has a 30 day return policy check with them first and make sure it applies to carbs. u'd just be out the shipping if it's wrong or you decide to go another direction... Agree with a previous post that ur pic seems to match the stock pic on the rockauto website. (doesn't necessarily mean they are the same)
If the motor is a 250, it should have a Carter RBS on it that looks like this one that is on ebay right now for a starting bid of $85 UPDATED: Nevermind - the RBS was used only through the 1974 model year.
