  1. Hasn't been that cold ?But- no power too fuel pump and would not fire with ether (starting fluid)That's what I came here for, thinking I couldn't be the first one this has happened to. Although this brat likes to be run every day-if it sits a few days it turns over like 30 times to start-if everyday just a couple turns and its running some one said this year was set up to run fuel pump when key is in start position and not just- power-will power fuel pump ? ?

  2. Inside of cap was dry before - how long an far? Leave my newer ford home, Drive all the time when ever I need to go anywhere 3 to 5 times a week Usually not to far town is about 80 miles round trip.When I got the Brat last winter got no information or history with it,So i replaced a lot of the cheaper parts-plugs&plug wires cap rotor module coil pvc oil psi sending unit water pump oil pump alternator ignition switch (couldn't get key out half the time)All filters air gas oil and All fluids and all air lines Had a problem few months back,And had the carb rebuilt Twice not right the first time.Cleaned out fuel tank had hole fixed replaced and blew out lines and put on a new fuel pump. AND now several months have just driven it,Parked on side hill and car wouldn't start rolled down to flat ground to work on the next day .Next day it ran but didnt go anywhere that day next day would not start No Way And No did not wet plugs,, sprayed sparingly a little at a time trying to start.I had pulled plugs earlier to see if they were wet with gas from trying to start day before they were not.

  3. IT Started right up ? Checked everthing as was suggested above,The coil plugs plug wires dis cap rotor control unit are all new checked anyway,as well as grounds new fuel pump new ignition--- pulled fuel pump controller out took apart nothing burned (don't know how to test) put it back together an put it back in.Turn the key and it started ?So I will get new fp controler,Thinking it may quit again if thats what it is,Or was ????thank you all

  4. Okay Now that I have your attention , Do have wires either side of carb and one towards front right and one to air cleaner bottom.Still not seeing computer, And if it has not got one ? What would Stop the engine from starting and not pump gas------New fuel pump--That has been working fine.Still have spark at plugs --Will not start Even with starting fluid NOTHING Is there another sensor?What and where ?Thank you

  5. Just had carb rebuilt called an talked to rebuilder about above condition of brat,he said same thing about blocking alt-comp and said very doubtful that it was running short of gas that even if gas is at bottom of glass an just visible,that the jet is in very bottom and would have more than enough to run as it should,he didnt ask about altitude though?That is about 1750 feet? He did say somthing about rejetting the carb as it was all back to stock specks at rebuild,saying maybe the thing to do because of it being a high milage rig,didn't think that 300K was to high for a subaru It sure runs good, until it doesn't I will try running and shutting it down at just that point of weakness it jumps back an forth fairly quickly . thank you

  6. Okay all hose has been replaced,then blocked off altitude compensator,And it restarts and runs pretty good even after driving and getting up temp and shutting down, when before on restart it it would not unless cooled down with water or time. But now third gear at about 50 to 55-3K on tack it acts as if its running out of fuel 55 down to 50 then back again over and over, not wanting to go above that . Cant go fast enough in 4th to get it to do again,not doing it in second at same rpm So now what?

  7. Found two very short vac hose's that I had past up on earlier guest's.Went through- every - thing one more time vacuum switches ,found restrictors in tacked , in tees ?   And so far so good,Very good   THANK YOU ALL AGAIN dont think you can beat this site for information and help some times hard to relay a problem( 4 me anyway )

  8. You could cap the output port and be done with it or you could look for the upstream problem.

     

    Not all that hard.

    It will be a bad diaphram in the 2 port vacuum switching valve or the 5 port air contol valve.

    If neither of those then it might be that the inline restriction orfices are miising from one of the 2 hoses between the air control valve and the carb.

    Both should have .022 inch.restrictors.Little brass jobbies I think.Easy to miss when replacing vacuum lines.

    Try blowing thru those lines.

    You could possibly make some or snag an original line w/the orfice from the wreckers.

     

    Another possibility is that all of the above are OK,but,the carb is marginaly lean already and the control valve leaning it out a little more by opening

    the air bleeds at high underhood temps pushes it over the edge.

    Carb cleaning or general vacuum leak reapair required.

     

    My money is on missing orifices.

    thank you for your time, the help is very much appreciated wish I would have asked for help many headaches an dollars ago,hard to do when your convinced the next fix will be the one.Also makes it harder for me -trying to keep it as it was built.Have no problem with a carb thats worked  30+years 10s of millions of miles        very humbling this little brat,

  9. spend the day off an on replacing hoses then some more hoses and clamps ,then drove it to parts store to get more hose,ran like crap all the way up an back-finished plumbing and went for another drive                       it was a quite nice drive, thinking needs to have that two port heat sensor replaced let it sit about 20 mins whet back out a started it and it s doing same as before?I can try the quick an dirty tomorrow see how that goes?  

  10. I did clean out lines when I did fuel tank New filters before putting the Hitachi carb back on---I will redo all lines, and I'm liking theory of of bad windings something is getting hot or hotter when first shut down and then after running for a short time seems to want to run like nothing ever happened.                                                                                              like a  opened minded girl friend                                                     thanks for all the help everyone.Court

  11. I have 85 brat got a couple months ago,been working on it ever since.It starts right up runs pretty good,I can drive it 5 miles or 50,But when I shut it off, run in store or what ever, get back start it up it idles fine - so as you put power to it it wants to die push gas pedal a little more ( or feather the pedal )you can get higher rpms to get it to go. Then using clutch as to get it going much like a bucking bronco,Drive a little maybe a few miles it goes through the flat spot   an in to higher rpm an all of the sudden it starts running fine again???  have removed tank cleaned an sealed new filters-had carb rebuilt ,new cap rotor- module- wires- plugs-egr-pcv-coil-?timed-not running hot  So What have I missed?  So far it has always started fine and runs good UNTIL I stop and then want to go again.
