Hi all
I'm new to the forum, and to Defenders in general, so forgive me if I talk any nonsense.
I've got a problem with my 1986 2.5 petrol 110, that's been baffling a few mechanics over the past couple of months.
It started when I had the head gasket changed, which seems to have got the engine running a little warmer than usual.
It runs nicely at lower temperatures, but if I'm driving at 50 or so for any prolonged period (usually an hour or so), with the engine running a little over it's usual temperature, all of a sudden I'll hit the throttle and the revs won't do anything. A few seconds later the engine will cut out altogether and I'll be over to the side of the road.
When I fire her back up, there's a rough idle which stabilises when I put my hand over the air intake (so a fueling issue presumably?). I've noticed vapor leaking out of the carb a couple of times at this point. I can limp off with the choke way out, leave it to cool for half an hour and it runs again fine.
I put a new coil on just in case, and the rest of the ignition stuff is all new and fine. Fuel pump sounds alright.
Am I right in thinking it might be a carb thing? It's a weber carb, and I've heard that one of the solenoids can fail when hot, but I'm not sure what affect that would have on the running.
Any help would be much appreciated with this. I've never managed to replicate this state in front of a mechanic, and I've been spending quite a lot of quality time with the hard shoulder.
Cheers
Harry
