If you've reinstalled the preheat tube blanking plate and still have the issues I'd change focus to the ignition system. I'm suspicious that the electronic module that you have installed in the distributor may be breaking down when hot. This may result in a weak spark that seems to be indicated by the fouled plugs.
Yes the original carb, inlet manifold, electronic ignition have all gone and replaced with original parts though the dizzy has a petronix module fitted now. You could be right about the ignition module breaking down but one of the reason I went that way was to get some reliability into the ignition as I know the condenser was suspect. The module has only covered about 800km so I hope it is still OK. I haven't blanked the carby heat pipes but have fitted the insulated spacer.
At the moment - I think I have two issues that are separate (maybe). When cool the engine runs and idles well but is down on power. When hot it will not idle and is still down on power. In the past the low power aspect has been caused by tight tappets causing valves staying open a little and dead spark plugs. I will look at this today.
When the Haflinger is going well it really goes great - and with it new high speed gears and 14" wheels and tyres is fast (for a Haffie) without over revving the engine, it is just that for some reason it goes suddenly off song for no apparent reason.

As to the LR101, they may be many things but as capable as a Haflinger I assure you they are not and far from it if off-roading is your objective. The LR is simple and rugged but they certainly have lots of reliability issues so don't expect not to have frustration with one of these beasts too. As they say, been there and done that so there will never be another LR in my life.

I was actually referring to the series 1 in the above pic being as capable as the Haffie - even without difflocks it is a good as the Haffie overall and with difflocks would eat it up.
The 101 is mainly limited by its size and clearance under the diffs where the Haflinger has a size and manoeuvrability advantage but is limited by its stability. Overall my 101 which has difflocks is as good as A Pinzgauer off road and better onroad. It has fare more stability bit doesn't have the clearance under the diffs.
As John mentioned above, the Haflinger would never have worked in a warlike environment as it was too complex to easily maintain. The Pinzgauer replaced the 101 in the Brit Army and the Brits found the maintenance issue out when they were used in the middle east.
The old series 1 have under a tree in the back yard works but I have been trying to do an engine change in the 101 (go from 3.5litres to 4.6 litres and everytime I get going on it the Haffie gets jealous and chucks a sookie.
