    ,85 BRAT, Hitachi, 49 state, new fuel filters, old loud fuel pump, new front and rear fuel filters. The car will hesitate and lurch under certain conditions. If I let the car just idle still for a while, and then accelerate, there is not problem accelerating, until about 20 seconds into it, then the balking begins. The normal acceleration indicates to me that both carb barrels are working. I just drove this car up a 1/10 mile 7% incline several times. I let this car idle, still, at the bottom of the hill every time before I did the test. 2nd gear, 2,000 rpm, the car makes it up the hill just fine. 2nd gear, 2,500rpm, the car starts balking halfway up the hill. I am guessing the problem is the fuel pump, or the valve which fills the float bowl. Am I missing something?

    I need to replace the clutch plate on my BRAT. While the engine is out, what else should I do?

    I don't know! I installed the tires 1st thing upon buying the car.

    I don't know. Here is some information about the P7157. Maybe you can find a cross reference. http://random.removed.us/altswap.html mkoch

    Thank you for the follow up. I'd like to see pictures after you install the next piece. moch

    There is an aft heater hose, manual transmission, upper and lower hoses  for 7720 06290.  I can get a photo if you need it.  

     

    In the engine compartment, the heater hoses are upper 8076 15032   lower 8076 15042  

     

    My parts manual is 1984, which should be the same part numbers as yours.

      Thanx, M.

      Wish I knew how to get email notifications of posts here.

      Mine is automatic.

      There are actually 4, the long afts, upper & lower, then short fores, upper and lower.

      Again, thanx, sorry I didn't see sooner.

    At highway speeds, there is a vibration, feels like it's from the front, steering wheel cycles left-right about 5 times a second. I just had new tires put on. What besides tire imbalance can cause symptoms similar to tire imbalance? mkoch

    The vapor separator is available over on ebay. mkoch

    1985 Brat non turbo. I have a "vapor separator near the firewall, driver's side, (left, USA). Fuel comes from aft low in the separator, leaves low to go to the carb. Out of the top vapor returns to the tank. Mine is opaque, probably from age. Is it also a fuel filter, and should I replace it as preventative maintenance? Part number 7420 72020 . mkoch

    Does my Gen 2 Brat 1985 manual transmission have a rev limiter? mkoch

    I am going to purchase the carb rebuild kit from rockauto.com. It is made by Standard Motor Products. While I have the carburetor out for a rebuild, what else should I do? Edit 1985 Brat.

    I don't have one to sell right now but I did take apart one on my GL, 1984. It is a pretty simple mechanism, and easy to clean. I only had to clean off the grease, and polish the parts, and then it was like new. Take lots of photos, and be aware that there are some ball bearings and small springs which can fall out. Magnets can help retain these. mkoch

    It should indicate that the engine is running lean, or rich, or in spec. How is this not useful?

    Thank you GeneralDisorder! I plugged the hole with a sensor, I'll run a voltmeter off of it just for grins.

    My suggestion is to follow all laws all the time. Some garages doing the inspection for the state will look under the hood, see a Weber in an '80s Subaru, and pass it, even though the Weber does not have the emissions stuff on it. My mechanic saw the two catastrophic converters on my Brat, and asked my why there are two. The second one looks like a resonator, but also, it sure has a honeycomb inside. The what looks like original catatonic converter for my 85 Brat did not have an O2 sensor, no place for it. The replacement had a place for the sensor, so I put one in, just to plug the hole. He said it had to be plugged in to pass. He didn't say where. Of course, I found the right place to plug it in, but he would have no way of knowing. These cars, 30 and 40 years after manufacture, might not have the original setup. mkoch I am not a lawyer. Consult your attorney for legal advice.

    "Also, before you get into the project, determine if you need a catastrophic converter in your area. mkoch

    I ordered the one by "Davico" from RockAuto, for my '85 Brat. It should be the same as the 82. It fit at the exhaust manifold, and only sort of fit at the mounting bracket further aft. The bracket on the y pipe met the car's bracket at a 45 degree angle. Not easy to bolt up, but doable. I used my own welder to replace the stock type flexible joint from the y pipe to resonator pipe. The Davico 120021 Y pipe that I received had the wrong style of flange. edit- The DEC one is $70 more expensive. Knowing what I know now, I would still buy the Davico one, or fabricate my own. The stock flexible joint is just a bother. I now have the flexible piece connecting the Y pipe to the resonator pipe. There are only three flange gaskets my exhaust system. The two at the exhaust manifold, and one between the resonator pipe and the muffler. So, essentially, a two piece exhaust system. mkoch

    Heya, 1985 Brat 49 State, Hitachi carb. I replaced the Y pipe, which looked original (it had the air heater). It did not have an oxygen sensor. The replacement has one, and I wonder where in the wiring harness it connects.

    Thanks GeneralDisorder!

    Heya! Can you rebuild the ignition lock on a 1985 Brat ? I am pretty sure that it is the same mechanism as 1984 gl, and generation 2 s. I have a key which works, but not well. I’d need new keys. I could send the door locks as well. Pictures of the ignition lock. It was quite difficult to remove!
  24. mkoch
    It looks like I could use shorter studs if I remove this part. Will the y pipe bolt directly to the block? I am going to do the Weber conversion, so no need for the exhaust gas. So, is there any good reason to leave it on there?

    My plan is to remove the windshield on my 1985 Brat, repair the rust around the edges, and then have the a new windshield replaced professionally. I have a new gasket! How do I remove the old one?
