I have series what has the following problems:
Landy starts pretty easily and when warmed up idles very nicely. It can drive downhill ok and can accelerate a little. Going up any kind of a slight incline there is no power whatsoever, and if I keep trying to go uphill it just dies. Sometimes it also backfires. When I check the spark plugs they are black with soot.
I have tried :
Compression test all 125-140 psi, a little higher when oil is added
Adjusted tappets
Entirely new ignition system.
New genuine Lucas 45D distributor to replace the old 25D
Replaced condenser in this new distributor 3 times
Thoroughly filed, cleaned and gapped points
New plugs (2 sets), new wires
New coil, and then replaced that one with a known good coil from my Jaguar
Replaced old wiring from fuse box to coil and from coil to distributor
Adjusted ignition timing
Right on 6 deg BTDC at idle, advances (mark moves counter clockwise) when idle speed is increased
New vacuum line from carb to distributor
Entirely new fuel system
I rebuilt the Zenith 36IV with a genuine rebuild kit. Flattened all of the housings.
Replaced Zenith with brand new Weber
New fuel line from pump to carb and new filter (the filter does not fill up all the way, only a little less than half)
New fuel pump, inspected the old one which looked fine.
Removed fuel pickup line to check for clogs, all clear
Added 5 gallons of gas to tank to make sure I was not low
Fuel in glass sediment bowl is full and clean
New exhaust manifold (the old one was cracked by the down-pipe attachment)
New intake manifold gaskets and all new attachment hardware
Engine runs 50 psi oil pressure
Dynamo output seems fine, lights are bright and the battery does not run down.
Tightened fan belt.
Please can some one help
