I have an old '57 Morri' Minor with a huge 950cc engine.
Have had a problem that I can't seem to solve for a long time.
It's like a riddle or something that you don't know the answer to and I'm hoping someone can slap me over the head and tell me it's something obvious, cheap to fix and easy to fix.
When I drive at high revs (by high I mean when I'm going 50km's or more) the engine cuts out.
But only for a second since I can push in the clutch when it cuts, release clutch and it fires back up (if I'm in gear of course).
So I've tried to narrow it down to what it could be.
So far I have replaced the coil, fuel pump (twice), spark plugs, flushed out fuel tank and lines and cleaned carburetor.
Even double checked it wasn't fuel lines by putting a fuel can in car with petrol and running a new fuel hose to the fuel pump but no success. It did run a bit longer than usual but not sure if it's just 'cos the engine was hot. I did notice though that when it stopped and I didn't start it straight away, the fuel pump went nuts (like my old one used to) with the loud dry-pumping noise it gets with no fuel.
Running out of ideas and money at this point and really just don't know what it could be.
My brother in Hawkes Bay suggested problems with tappets, timing, resistance or points.
If anyone else has had a similar problem or reckons they know what it might be pleeeeeeeeease help.
