As you all know the b250 was a pig to start due to it having an inline pump. But were the early b275's with inline pumps as bad?
@Mur HuwcunThey shouldn't be a pig to start at all. My 250 and 275 with inline pump starts lovely now. Do you know about the 12v replacement heater plugs that you can buy or just make some using car heater plugs.
Most probably your injector pump will need an overhaul aswell, the elements wear and loose injection pressure
Par for the course I think. One little item which does have a pronounced effect on the starting, is the condition of the small end bushes, even the slightest wear here drops the piston down the bore, so lowering the compression.@Mur Huwcun
I've put new heater plugs on and it still needs heat for the first 5-10 seconds. Does yours?

wire them in parallel, by pass the pepper pot, heat for 8/10 seconds and away it will go
Think most internationals of the time like a bit of heat to start unless they are already hot.@Mur Huwcun

Indeed it does have a popping sound when it first fires into life. Also it is hunting a little on tickover. And it is also hunting when it isn't given any welly on the throttle, but in my opinion this is perfectly normal for an inline pump.This is the most reliable way of heating your nasher
Done it many time the plugs last so much longer than the original types.
Also check tappets good battery and clean starter out
Does it have a poping sound on tickover like a valvy sound but different.
Yes hunting is characteristics wouldnt worry to much of that,Indeed it does have a popping sound when it first fires into life. Also it is hunting a little on tickover. And it is also hunting when it isn't given any welly on the throttle, but in my opinion this is perfectly normal for an inline pump.
Throttle butterfly worn, and not sealing? Excess play in linkage?
Butterfly should be a very good fit, with no wear in the bearings. I have been told that general engine wear can cause this, worn valve seats can lower manifold depression, for example, as the cylinder charge is blown back into the manifold. Tight valve clearances on the inlets, and wide on the exhausts can also cause manifold pressurisation, this shows up by some very strange noises being heard from the air inlet area.
You could put a plough on, and do Sarn match. I too, have fallen into the too good to scrap trap! I have a Fisher Humphries trailer plough that I bought to save it from the scrap man! Never get to use it, the world style kit is so much easier to transport for one thing.
leave the tractor alone, and put a landwheel on the plough!
