Engine stalls when clutch pressed in

jims · Post by **jims** » Thu Mar 21, 2013 1:03 pm

Hey guys,

Any ideas on this one? When I am cruising along and come to a stop sign, give way sign etc, I press the clutch in and the car stalls. Before I left home it was idling fine but after driving for about 30mins it wouldn't even idle. I had to pulse the accelerator to keep it alive.

I'll check my timing when I get home to make sure it hasn't changed, but just wondered if any one had any initial thoughts?

Cheers,
James

Sounds like it could be timing.. the good thing (and there really isn't many times I say that about the EA82) is that you can remove the L&R outer covers and with the engine on the middle of those 3 little flywheel marks, you should be able to see the Camshaft Timing Marks at 6 & 12 o'clock

Sorry hit enter too soon...

If the timing marks are out, then it could be the adjusters weren't tight enough. Just think as you've had the front stuff off recently

and the adjust bolts torque is low like 15 foot lbs, not want to overtighten risk stripping
Is carby jim ?

Yep carby. I will check the timing advance when I get home and then check that the cam shaft timing marks are still in the right spots.

When you say the adjusters weren't tight enough, do you mean the bolts, or the belts?

Thanks Paul and Steptoe!

I was thinking belt tension, as from memory they required retensioning... after been 'run in' as to speak.

Must be sure not to tighten the bolts too much, as Jonno said, cause them to strip.

Just took the covers off t have a look. Before I got to inspecting the cam positions I noticed that both belts have slid towards the back of the pulley. Passengers side more so. Thoughts?

Hmm, after a closer look this doesn't seem to be a problem. The aren't 'hanging' over the cam pulley anywhere.

Okay, well the timing marks on the cams line up: 6 and 12 o'clock with the flywheel in the centre of the three marks. It is possible the belts are over tightened? They are pretty stiff as it stands...

Haha, argh. Any tips on tightening the belts?

jims · Post by **jims** » Thu Mar 21, 2013 7:47 pm

Okay more help needed. Re tightened the belt. All good until I realised it had slipped a few teeth and the alignment of the cams was out.

So I removed the belt again to re position cam to the right orientation...but...I can't spin the cam around. I'm afraid if I put too much pressure on the little bolts on the cam pully to spin it I will snap them off. Help!

Six hours later back to where I started. At least the belts have been re-tensioned lol.

Sorry James, had to sleep at some time

Ok, so the belts are correct (and now retensioned), I'd look at ignition timing and also for any hoses that might be off, mainly looking for ones around the inlet manifold.

Is the car idling lower than normal?

This is your engine just rebuilt and running sweet ain't it ? New belts are to be set tighter than than older reused belts. Sometimes have heard new belts that I thought must be close to overtight have this new noise never heard before - never seen 'em fail though.

Factory and gregories have a belt tension spec that most do not have measure tol or bother with. I have mostly felt that the spring of the tensioner gets a nice tension on the belt and no more is needed other than a little help from hand , once those tensioner bolts are tight - the spring does no tensioning - just waits there for a retension 40,000km later when you can't get at both tensioners other than through those plug holes in the covers - so need to rely on feel and those springs doing their job.

Must be a carby setting like throttle cable lock nuts left loose from previous overtension setting ?

Thanks guys,

I will double check for hoses that might be off. Ignition timing is spot on 8 degrees. I have had to turn the idle screw up so as to keep the engine running. It's sitting at about 1000rpm. Any lower and it starts to 'splutter'. Thoughts?

Throttle cable is locked into position.

So all the hoses are connected.

It would have to be either fuel or spark causing this problem right? I am leaning more towards fuel as the engine runs fine when you rev it up. Perhaps float level or something like that? Weird thing is the carby came straight off the old engine onto the new one. Nothing fiddled with except the idle screw.

Sorry guys, i'm thinking out loud more than anything.

Did the carby stay upright whilst it was off the engine?

I found that they are very temperamental if they fall over or get turned upside down.

jims · Post by **jims** » Fri Mar 22, 2013 5:12 pm

It was turned upside down, yeah. While I was cleaning it up. What could this mean?

It could mean that the float level is stuck and/or the ball in the accelerator pump has dislodged, stopping fuel getting pumped in.

Have you got another carby to try?

I see. Nah only got this one. Does this mean pulling it apart?
