Hey guys I am having trouble with my 4K in my ke70 and need advice or help on things to check or if anyone has had similar problems. today I was covering a bit of ks and had done about 170ish ks in several separate trips had been fine all day when all of a sudden down the freway it started breaking up I have isolated the problem it will only do it in 4th gear when holding a constant speed. under acceleration it is normal when I let of the pedal and deceleration it is also normal no breakup ect. (On a side note it also stalls out when trying to down shift from 4th to any gear as soon as the clutch is pushed in idle just drops to nothing and stalls out) So the problem kind of feels like a bunch of mini fule cuts happening over and over constantly when cruising as stated above. Keep in mind it was doing this before and breaking up every now and then but nothing concernable in the same conditions as above. (This would happen like once or twice every 2-3 km then be fine where as now it is basically constant) it is like it is having trouble holding the fule at a certain level while cruising but only in 4th gear my initial idea was a fule like split or something so it was sucking in air however under heavy acceleration it is fine and does not do it. Maybe a spark plug but then why is it driving fine in every other gear and any other time. Is my flywheel or clutch catching causing the jumpy feeling? Never heard of this issue before but who knows? Is there any fule solenoids or fuses ect I could check? any ideas help as I’m a bit lost atm cheers fellas

I also have another question do you guys know if the clutch out of a k40 fit into a k50 or will I have to order a new one?

No worries Thankyou guys I fly out again ahah will be back in about 2 weeks so will be able to have a play with it then check some more things out see what I can work out

So if I got this right that red dot on the dizzy should be on the other side (left hand side) of the brass arc and that will be a lot closer timing? Then you think grab the timing light from there and check to see what it does

Alright I have had a brief moment to mess around with everything I found a vacuums line unpluged and have plugged that back in that was for the vac adv on the dizzy did not fix issue I think it’s slightly better but that could be placebo. i replaced the fule filter quickly that was filthy so that should help me a bit now I have lined up the timing marks like you all suggested onto 0 deg taken my dizzy cap of taken a photo and then put it back on taken another photo so you can see where the top of my finger is is about the middle of that brass arc when it is at 0 deg. So it just misses the number one lead at 0 deg i haven’t had time to get a timing light yet as I fly out again tomorrow but from what I can see there it is a little out still am I right in saying this? also the rotor turns to the left (anticlockwise) when the engine is rotated clockwise so does that mean turning the dizzy clockwise will advance it and turning it anticlockwise will retard it. the more I look at it and think about it the more I am led to believe that it has been installed a tooth out so is it as simple as pulling it out rotating it a tooth in a direction then putting it back in? anyway please let me know your thoughts and what I am doing wrong or some other things I should try cheers

Hi banjo located perth Western Australia currently not home atm so haven’t had time to tinker with it but when I head back in about a week or so will have a look and see what I can work out I will take the dizzy cap off ling up my timing marks and send thru some photos on here to see what I can work out and see what everyone recons

No worries I’m trying to go off memory here as I am not at the car but now you say that with the dizzy timing I might have that round the wrong way I am honestly not sure will check when I get back home in a week or so time but will look into a timing light as that might work out to be my best friend here cheers for the help will give those few things a tray and see where it gets me cheers guys

Paid bang on the 10k mark was pretty happy with it no major rust or anything very clean car overall interior in near perfect condition to one small rip in carpet and a small crack in one of the door cards. i do not have a timing light so I was using the pull the top of the dizzy off method and lining it the first striker up with 10 degrees so turning the dizzy to the right advances it it is currently sitting all the way right atm so something is not quite right because lining it up with 10 degrees is all the way in the left position but yes next step for me was to check the fule filter ect is not blocked and fule pump is pumping with nice flow then go onto checking the float and the keys ect however not really sure what I’m looking at tbh so any help is appreciated

Hey guys just picked up a 84 slant nose and am having trouble with tune or timing or both and need a little advice as I’m new to the carby game and want to learn. so long story short I am 3rd owner first was a older lady who put most of the ks on in then parked it up in the shead for about 2. A guy then brought it off her and did a bit to fix it up and get it running this included Fluid change throughout, new rad and hoses, thermo fan, new dizzy elec ign vac adv, coil , leads , plugs, carby rebuild kit, rpm guage, and a few more things not important to the problem. so my problem is driving at freeway speeds 80-100kmph (3500 - 4000 rpm 4th gear) the car will have what I can describe as the odd hick-up or cough where it will jolt for a split second and break up only to keep driving normally this happens pretty consistently but at random intervals at this speed (it is fine any other speed however haven’t really tried going above 100 kmph as I don’t intend to). Also to add to the problem when downshifting from 4th to 3rd if I take more then a second or two to downshift the rpm will drop to low and the car stalls out on me unless given a jab of throttle to keep her running. Weather or not this problem is related or not I am not sure. And the final problem I am experiencing is to do with the tuning side of it(I believe ) ,where I find myself not being able to get the idle to drop below 1000 rpm and when I did have it down around that 1000 mark it was not idleing smooth at all. so what I have done to help progress on my issues. I adjusted my valve clearances that’s helped quiet the motor a lot and make it smother overall. I have done a fresh service throughout new belts oils plugs ect, I messed around with the tune a little to try teach myself a bit about how it all works, and finally I checked my dizzy timing to the motor because I am running 98 octane I have based the timing off 10 degree btdc (that is pretty much my dizzy clocked all the way over to the left or turned anticlockwise as far as it can go. (Please correct me if I’m wrong on this part) so what I have learned from all this valve clearances helped a bit aswell as a good service I have gained a basic to slightly advanced knowledge of how the tune and timing and all that come into play and work together. however my problem still exists I could not get the car to run correctly with the timing retarded to where it is supposed to be it would idle horrible and I couldn’t get the rpm to change enough to the point I could start implementing the idle control screw. so I have set it back to where it was where it ran nicely but had the hickups. After playing around with it richen it a touch I checked plugs and it is still to lean so now I am running out of ideas and things to try On my list of things to try and check is fule pump, fule filter, check for any vac leaks (fixed one already) and spray around the carby and intake manifold with break clean or something to see if I can notice a rpm change when running to indicate a leak in the gasket. now I have probably missed a lot of basic steps and things to do so please correct me or point me in the right direction even a basic tuning guide for the 4kc would be mighty helpful or any in-site if any of you have had the same problem or simalar or think you know what the issue might be sorry for the lengthy post and sorry if it has been covered already cheers wizards Also there is a pic of Alice in all her glory
