Can an engine (motor) get so tired, it won’t run CNG yet still run Petrol?
First post gents, so be gentle with me. Please think in the context of barnyard engineering with this question….

I’ve a 60s Land rover with a low-comp cooking-engine so tired the oil-light goes on. Yes, I know I shouldn’t but to get round this I run snake-oil syrups in the thing (Lucas Oils Heavy Duty Oil Stabiliser’. The snake-oil has been in there for years. These Land rover engines are famous for two things, 40mph and not much more, and running forever.
I’ve been waiting for the day it finally stops, only it keeps running. I don’t need speed where I live so it’s fine.
UK petrol is four times what you’d pay anywhere else in the world, thus it runs CNG. This always killed any power it didn’t have anyway, yet this works for me.. The power has been getting less and less. Thing is, it still runs well enough on petrol. Runs on CNG provided you don’t give it any load. Compression-test shows all four pots are low but even.
I’ve checked all the obvious stuff, and minded to this thing, happy to run with vacuum leaks, timing way-off, and worn plugs etc. And I’ve fixed all that, I can’t understand why it won’t run on CNG. I’ve changed the reducer, fixed all the faults it was previously happy to cope with.
As I said, runs well enough on petrol. Runs on CNG provided you don’t give it any load.
I suppose what i’m asking is, assuming there’s no daft fault robbing power, is there a point where an engine can be so tired it won’t run on CNG, yet will run on petrol? Hence the day of the rebuild arrives, or should I keep looking for another reason?
