help. rough running after engine swap

[Jimbo4040]

First post so excuse me if ive put this in the wrong place.
Have just swapped cg10 with cg13 after head gasket started going on 1.0. Have fitted it to standard cg10 early gearbox. Firstly the clutch is barely biting and is at the end of the adjustment.
But the main problem is it's running really roughly. Seems to be way too rich stinks of petrol. Only seems to be a problem at low revs. Earlier the code readout was 21 I think. Which is ignition fault. But I think I've remedied that. Nowits reading 13 if I remember correctly.
If anyone's got any ideas they'd be welcomed

hi welcome
did you keep the 1.0 flywheel ?

 

[Jimbo4040]

Yes I did. Had a light 1.3 flywheel but wouldn't fit the gearbox/clutch

ahh i remember my coolant temp sensor was disconnected on my swap, had this sort of problem but with check light as well

 

[Jimbo4040]

Yeah engine light on. And fan running constantly. So im going to investigate the engine temp sensor tomorrow. I'll use the one from my old engine. I know that one works. Got any ideas about the clutch issue?.

i saw a mention of that in the workshop manual pdf jimbo, i forget what the diagnosis was tho, and i have the same setup, without any clutch issues

Think I might have put it together the wrong way round. Is that possible?

the friction plate backwards ? does it grip and release ok ?

 

[Jimbo4040]

Grips like a clutch that needs changing. But can kind of bite if I keep imy foot down

Aah turns out the engine temperature sensor wasn't plugged in properly. At least that's stopped the fan running. Its still running rough. But i unplugged injector on cylinder no.2 and it made no difference. So I guess it's running over rich to compensate. Spose its not helped by the fact I've got a janspeed manifold so the lambda is only reading 2 and 3.
Are the cg10 injectors the same cause I've got those on my old engine. Think I'll just fit one of those if they'll be ok

 

[frank]

yes the injectors are the same jimbo, and it should run on 3 if you disconnect an injector

 

[Jimbo4040]

Was definitely injector 2. Have fitted the other one. Runs nicely now.
Clutch is still barely able to take any form of power though

ahh nice one jimbo the little 160mm clutch should take upto 100hp, i had to build a hybrid 160/180 for mine.
was it a new plate ? what make was it ?

 

[Jimbo4040]

Brand new exedy (never heard of them) but can't be too bad though. New pressure plate and bearing aswell.

well known brand (with mixed reviews) i think the clutch wont release properly if its in backwards (the cushdrive hits the f/w bolts iirc) praps the thrust race fork is misaligned ?

 

[Jimbo4040]

It shouldn't release or shouldn't clamp properly if it's in backwards?

 

[frank]

it wont release look, the preface 1.0 fw has a very shallow dish

90% sure it went on that way round. Cause I tried it one way and it just didn't sit right. So i think it's on the right way im fully adjusted up atm. Will go out and see if I've just somehow over adjusted it later

 

[frank]

post a pic of the clutch arm from above, and i,ll compare it with mine

 

[Jimbo4040]

Have just unwound clutch cable so that the bite is just above the floor. Can now put most of the power down. I think it'll bed in so I think ill leave it for now and see. Thanks for the help. Will post an update soon

 

[Jimbo4040]

is there any way i can use the 1.3 lightened flywheel that I have, what can i do to change the offset between it and where the 1.0 flywheel sits.

nah, too much dish mate (you would need about 25mm spacer between the engine and box) and the thrust bearing is a smaller dia, and would miss the pressure plate fingers

Aah ill give it a miss then. Just need to find the cause of the gearstick rattle now. could be the incorrect bolt I used in the linkage cause I couldn't find the original

 

[Jimbo4040]

Had to swap out injector 3 aswell today, will change the other two aswell, save any issues later.
