Hey guys,

 

My ke55 started to run rough a couple of days ago. On Start up the car idles fine, drive off and at low rpm's (2000-3000) in gear the car sounds like it is missing/spluttering. Stop at a set of lights and put the clutch in and it dies. I did a search yesterday and found a possible problem (fuel solenoid) changed that over to another one I have, new plugs, new dizzy cap, and rotor button, cleaned the points(bought a new one but haven't put it in yet.) Car accelerates well, though when I back off the engine sounds like it is only just going due to engine braking. Carby was changed just over 2 months ago to a working model off my previous car, fuel filter is new(3000km). I am going to buy some carby cleaner tomorrow and put it through. New leads have also been ordered. I am lost and don't know what it could be.

Cheers for any help in advance, and Merry Christmas,

Crowie.

Checked oil and water for signs of a Blown head gasket. Sounds like when i had my SLO-030. only give away was that it wouldnt idle and bubbles in the radiator.

check for vacuum leaks? coil not arking out to the negative side pole?

Not a head gasket, oil and water not mixing. Have checked for vacuum leaks but can't find any, coil is locked in tight and not arching. I'm starting to think it is carby related? Carby was off a working car for 12 months then just chucked on. Will be booking it into see someone asap, as I am totally over it.

wiggle the fuel solenoid wire and see if it makes a difference!

I've wiggled and fiddled with almost everything on the car to try and fix it, I changed the solenoid over and checked if it worked, wiggled it a few more times. Seems I might have a similar problem to ac17 "Do I have a Carb problem".

points gap and timing?

points gap and timing?

yes and yes. 0.45mm and 46 degrees

I havnt worked on a K carby before, how hard is it to ckeck the primary jet/ bowl? Id give that a go.

you have to take the top of the carby off. a couple of screws.

 

REMEMBER if the screw are very hard to undo. give them a tap with a hammer this will loosen em up!

Thanks Evan, i think most carbies are the same lol. If you strip the top of a screw, its a bitch to get. Grab a pair if vise grips, force farker out! Or a cold chisel, works well.

this sounds like exactly the same problem i just went through! tried everything and no results. I figured it was the carby but i was wrong, i first fitted up a set of extractors before i swapped the carby with a weber and got rid of all the EGR equiptment on the 4k. I thought i might just start it and see by chance the problem was still there, so i started it went for a drive and no more problem!

 

So id suggest ditching all the egr shit and block off all the ports and see how you go, or if you want to keep it take it all off and give it a good cleanout as mine was 99% blocked and it only had 130 xxx on the clock.

Also check to see that your inlet and exhaust are alighned or have not separated from the head. It only has to be a tiny gap for it

to make a difference.

I'm having almost the exact same problem. Do you find it runs like shit in the cold and stalls at stop especially after freeway running?

Not that rough on cold start, though it doesn't get cold up here. after a freeway run it is very rough. Tightened manifold bolts and changed points and it has stopped stalling, though it is running very rough. New leads next, if that doesn't fix it then I will chuck on twin SU's I have or maybe just one.
