My series 3 is giving me a headache at the moment. Its a 1981 SWB 2 1/4 petrol. When I bought it last month, it started to kangaroo and lurch on the way home. Since getting it back, I have, changed the carb for a shiny new one, changed the fuel lines, plugs, checked the tank for crud, and removed and checked the fuel pump for the same.
I redid the timing this morning, and it idles fantastically. The revs increase nicely with both gentle and sudden acceleration. The mixture seems spot on.
The problem starts when I take her for a drive. She drives fine from standing, but within a few minutes or so, starts to lurch, and loses power. I can just about get the revs up when she slows.
I have fitted a clear inline fuel filter (the correct way round) just prior to the carb. This thing never seems to have any real amount of fuel in it, which I find strange. When I get the power loss, If I check this filter its empty or virtually empty. I had the fuel pump off again this morning, and it gives a good squirt of fuel disconnected so assumed its ok. Replaced, and the same happens, virtually empty inline fuel filter. The pump seems to work fine when off!, but not when its refitted?
Im going to replace the pump with a brand spanking new one, as I cant see anything wrong with the diaphragm etc on dismantling the current one. If that doesnt fix the problem I have no idea what to do next. Having never owned a series landrover, I am wondering if anyone can answer if:
1) When you hand pump the fuel pump, it should squirt fuel fairly soon after pumping? (Mine pumps for ages and I dont seem to get any real flow)
2) Should the inline fuel filter be full of fuel, ie more than a dribble in the bottom, or does it fill, empty, refill etc etc. Mine seems to fill a small amount, then refill a little at idle. I'm guessing when driving and accelerating in say 3rd or 4th its struggling due to fuel demand, but is fine at idle because there is very little.
All answers and advice gratefully received, as I want to get her sorted for the winter!
