engine runs on after switching off

Hi folks
I have had the Uno Fire motor rebuilt last year, the head rebuilt with new valves last month and a new ignition module this last week.
Prior to the new ignition module being fitted the car would carry on running after switching off, and the only way to stop it quickly is to leave it in gear and let out the clutch.
Now the car has all the power does not over heat but still has the running on after switching off, although not every time. I did two trips yesterday one to the shop - no problem, and then one home again - engine ran on after switching off.
Any assistance would be appreciated.
Kindest regards
Graham Lawrence

Re: engine runs on after switching off

Run on is often associated with a too far advanced ignition timing.

I would check the static timing to begin with. If this is OK then look at the dynamic and vacuum advance.

Not clear from from your post if you have a carb or fuel injection.

Post Re: engine runs on after switching off

In new generations of Fiats (like for example Grande) problems like that are mostly electrical (wiring).
So consider this also (but OK, in older ones it will be more mechanical: bad timing, carbon deposits, etc.).
