MG MGA - Winter lay up effects

What is it about winter lay up that effects car tuning?

I had the car well tuned last season.

After fixing my bits and pieces, I started it up for the first time and after warm up it was galloping at idle.

Sigh...back at it. I think the first stop will be to clean the air filter. Not that it will help much, but its a start.

Tysen,
Sounds to me, you may be running on one carb. It could be a sticky needle and seat in the float chamber.
Turn on the ignition, wait for the fuel pump to stop clicking/pumping. Then take a wrench and lightly tap on the float chamber,if the pump starts to click again,it most likely is the needle and seat sticking closed.
This happened to me a few years back. I add a little Marvel Mystery oil to the gas. Half a pint for a full tank is about what I put in. Not sure if that helps, but I haven't had a problem in a few years.

Good suggestion.

I'll give it a go.

I took it out for an Italian Tune Up and it seems much better. It still seems to gallop when the temp is under 160.

Stuck choke?
