Did a great 250 mile round trip, ran really sweet! Then parked it up for 3 days.
Started up and it sounded a bit rough.
Runs ok at high rpm and pulls great at high rpm.
However, no torque at low rpm...
If I'm doing 30mph in 4th gear and accelerate it judders, kind of like a missfire.
I have gone throug the electrics checked the leads and cleaned the plugs with a wire brush, checked and cleaned the distributor and rotor etc...
I'm a bit puzzled?
I'm not sure, but it may be running a little rich???

Anyone recodnise the symptoms or suggest any possible remedies???

Thanks in advance

Time to check your exhaust gas composition indeed
