1965 230s engine troubles

[douwi230]

After about 2 months at the mechanics, I have finally got my beloved 1965 230s back on the road.

A culmination of events (lost keys/broken suspension) led to the car sitting idle for too long and the petrol going off in the fuel system. My mechanic had to remove, clean and reskin the fuel tank, and replace the carbeurators (cleaning out the fuel lines etc along the way).

It is (generally) running better than it ever has now.

However there are a couple of side effects of this overhaul.

The is now a petrol smell in the car which I can only get rid of if I drive with the window down.
Also the car appears to be misfiring every now and then when I accelerate - it didn't do this before from memory.
And finally every now and then (once an outing) I get a puff of white/blue smoke when I accelerate from a stationary position (though not when I first start the car).

Does anyone have any advice on these issues? Have some things been missed/forgotten by the mechanic when they were doing the carbs?

Thanks

Re the smoke issue;
It's been a long time so I can't be certain but check to see if there is vacuum control to the g/box (modulator pressure control).If it has, this diaphragm may have a leak (does the gearshift on light throttle seem hard?).This is assuming that the car has an auto box.
Also check the servo hose for signs of brake fluid in it.

I have not owned petrol cars for a long time but the one thing I do remember was how the fuel lines perish and crack. The 230s is a lovely motor but I would give a thought to the fuel lines, they are not so difficult to do. How happy are you wil the float carb float level?
