could someone with one of these engines please tell me whether they get a vacuum on the pipe on the air intake box (the pipe which connects from the bottom of the airbox to the warm air flap) when they engine is hot. sorry for a nearly replicated thread but i need this car on the road o how i love them yet hate them at the same time [:^(]
but the one that goes to the flap thing i dont seem to have any vacuum. does this mean the temp regulator in the airbox is fahooked
Yuh they should have vacuum pretty much all the time, regardless of how hot the engine is For now can you not get an adaptor on the pipe to join the 2 together, or bodge the flap open about half way with a screw through the housing?
ooo good idea!! i'll give that a try, other than that warm air flap do you know if there are any other methods of warming the carb on this engine...im certain i have carb icing but am unsure how to fix it
Well as long as the inlet manifold preheater is connected up, as well as making sure it gets good coolant flow to the choke unit that should be enough The warm air feed IS important though, with mine disconnected I get carb icing. I also got icing when the metal manifold plate thing was removed (sheared bolts) it isn't enough to have the pipe dangling down there Check you get 12v to the inlet preheater with the engine cold and the ignition on
ok ive bodged the flap in the airbox open just over half way and havent had any trouble with it yet could you tell me where i can locate the pre heater and perhaps what it looks like?
The pre-heater is bolted into the bottom of the inlet manifold under the carb, it will have a thick wire coming out of it. Check it gets 12v, and that the heater passes current (1 multimeter prong on the plug, the other on the manifold body somewhere)
thanks for your help guys, ive got a temporary fix and waiting for the temp regulator in the airbox which was found to be faulty after two days of scratching my head
ive changed this temp regulator but its not made a blind bit of difference! when u talk about coolant flow to the carb and carb pre heaters...i cant seem to find any of these on my carb, its a 1300 carb (solex)...will this carb have these components?
It would appear not according to the Haynes manual. So the warm air flap still doesn't open? Do you get vacuum to the pipes connected to it?
no the warm up flap now opens with the vacuum from the back of the carb i think a new carb is in order, does anyone know where i can get a replacement for it (1300 carb)....or better still a second hand weber that will fit?
well after 5miles of driving, the carb splutters and then stalls, if i leave it for a few minutes start it again, i can drive normally again til the same problem occurs...this is the only logical solution i can come up with....ive tried everything else people have suggested yeah the warm air pipe is connected
Sounds like the fuel pump then, my dads 1.3 would cut out randomly on long jorneys. The last time we broke down the AA man correctly diagnosed a lazy fuel pump Replace the air & fuel filters if you havent already done so, and start looking at the leads, dizzy cap & rotor arm. My girlfriends AX would cut out very easily whenever a load was placed on the engine, new dizzy cap & rotor arm sorted it
Well, mine ws originally a 1300. I had problems with it stalling and not running right etc. It turned out that the rubber mounting that the carb sits on was split along its rear edge. I suppose after 5 mins, the rubber was warming up and softening a little, allowing the carb to rock, causing the split to gape and letting the engine suck in too much air. Have suggested this to others who have also found splits... AL.
good ideas guys, but ive replaced the fuel pump, fuel/air filters and carb base gasket as described by AL*MK1 oh and ive replaced cap rotor arm, leads, points, condenser, ign coil, not much left is there Edited by: K13_RAN
