I just bought a 1988 Nova 1.0 for 50 euro (about 30 pounds) with three weeks MOT.
But the engine doesn't run on all four. It comes to 65 mph on the highway with almost full throttle.
It almost refuses to accelerate, even considering the 1.0 engine. It keeps running on idle without problems.
The firing sequense is ok, one sparkplug was covered with oily carbon stuff (nr.4 counting from waterpump) The others were a little bit too dark for normal, but ok
I couldn't find a hole in the piston by scraping a screwdriver over the piston through the sparkplughole.
I took the airfilter off and the carb is covered with oil inside. So it's getting oil via the sumpventilation.
What's wrong with this thing? piston rings ?
It doesn't make strange noises.
Any tips/opinions exept "replace engine" ?
Even if I replace the engine I'd like to know what this is.
