|
|
My SD1 is stalling.Its when i press the accelerator pedal,i'l try and describe it best i can.When the engines warmed up i press the pedal(Not hard) and the revs die and make a low sounding noise then press harder it catches up and revs normally(towards the red).Again when im not pressing the pedal, the engine ticking over, i put more pressure on the pedal(so it revs faster)the engine overcomes the stall quickly.I suspect the carbs but unsure.Anyone else had this problem and how they fixed it?.The engine has stromberg carbs.
Thanks |

My engine did that when cold... it was the automatic choke stuck at off position. So maybe your is stuck so the automatic choke is always on? _________________ Owner of 3 Rovers and 1 MG.

Thanks for replying Lehto.I checked the automatic choke(Do you mean the F.A.S.D[Fully.Automatic.Starting.Device]?)and its not stuck or sticking.When i first start it from cold,the revs rise over 1000 rpm.Then drop after a few seconds to around 800rpm.I revved the engine (near the throttle linkage,not the pedal)and the engine was on the verge of dying.
Plus the engine is running very rich.Do you think the carbs are at fault?.Im thinking the carbs need a full rebuild and tweaking. |

Im about to do that myself to my car. Its not as simple as it sounds. You need SD1 efi fuel tank, fuel pump, fuel line and return line and all the induction bits. Plus you need to make a few wire changes to the fuel pump one.
Does ramon have any tutorial for this? _________________ Owner of 3 Rovers and 1 MG.

Rimmers is expensive enough for these parts. I'll stick to the trobulesome carbs for now. |

I wouldn't touch an olde efi setup with a barge pole. Just a pile of problems waiting to happen.
And, with all due respect, if you can't sort carb problems, you'll not have a hope in hell of sorting an efi what with dodgy loom connections, sensors, ecu, etc.
Get rid of the FASD carbs, and get an early SU setup from an SD1 or Landrover, with manual choke. Or if you're not bothered about originality, go for a 4-barrel setup from RPI.
Keep it simple.
If you want to fix your existing carbs, overhaul them as per the Haynes Book of Half-truths. Before doing a full overhaul, you might start with checking the float level, the dashpot oil...
Have you got an exhaust gas analyser?
The Gunson is not to be sniffed at, I use it every six months to check the mixture on my carbs. You also need an airflow meter, Edelbrock do one, for balancing.
But steer clear of efi

HAVE YOU BEEN SMOKING CRACK?!!?! EFI > Carbs any day. When your fitting an efi system to replace carbs its not a big job to go through the efi loom for bad connections. You get more power, better economy, better emissions... carb good points vs efi? Simplicity? You cant even defend the carbs price vs an efi system if your replacing SU with 4barrel because you have to buy whole new carb and intake. _________________ Owner of 3 Rovers and 1 MG.

Thats possibly true,it depends on how capable a person is with mechanics and wiring.

I am capable of sorting out carbs,did you notice i said i suspected the carbs in my earlier posts?I wanted confirmation from someone,so i wouldn't end up wasting money since i'm tight for cash.

i haven't checked these things yet since i am taking the engine out.

No,my family have a basic garage(for our cars) where if we need that we take it to a local garage.i know the car is running rich,the exhaust smells heavily of petrol.

Ouch! Does that mean since late 1993 after I got my TP running sweet as a nut and in the meantime, two Vdp Efi's likewise, that it was all a myth, and I really have to question how on earth my TP Efi System has been pretty trouble free for 14 years with the exception of a blown ECU.
Worse, should I now be considering changing to normally aspirated induction because the future is so bleak.
Oh Dear! I feel really ill at the thought of having to learn about carburettors. In fact i dont think I could face the future either way now.
Does anyone want to buy my TP?

Mostly those ECU "blow ups" are just cold solderings and by re soldering whole board the problem goes away. _________________ Owner of 3 Rovers and 1 MG.
