I plan to take the top of the carb off today and check the float level as a first step and I'll check to see if any crap has got past the fuel filter whilst I'm at it. As far as I know, the engine and gearbox mounts are as old as the landy (40 years) so they are worth checking too, I'm not sure of the best way yet though. I might mark the throttle rod position on the level then take it to a steep hill where I can park and where the revs drop and check the throttle marks to see if they have moved.

No, it's a Zenith 36

Thanks for the kind offer Dippypud but I already have a spare service kit, I bought two originally cos I cock stuff up a lot.I've got a gasket set for a Zenith 34/36 VN, if you're interested ?
Yes good tip. I was thinking of giving the lines a blow through with my compressor but maybe I should check the pick up filter first.My S3 had very similar issues, absolutely fine at a standstill, just about OK when moving, but any load, like a hill or towing, it would die.
I'd check the fuel pickup pipes in the tanks. On my S3 the cone filter/mesh was absolutely full of crud and when I tried to clean it, the thing collapsed! Just removing the filter from the pickup cured all silliness like the above. I substituted it with an inline clear view round fuel filter, which simply allowed fuel to flow properly and keep the crud at bay.
Just do a Mungo => Lean into the engine bay and see how far you can wiggle the engine. If you have a helper they might be able to see cracks / excessive movement in the engine mounts or the throttle linkage (you might be able to see that yourself as well). When I removed my obviously original engine mounts they didn't look too bad to me - new ones will now be fitted of course - but they seem pretty simple resilient (pun intended) things to me...I plan to take the top of the carb off today and check the float level as a first step and I'll check to see if any crap has got past the fuel filter whilst I'm at it.
