Hi wishing everyone a happy new year before asking a question.  Just checking my buggy has a 34Pict-3 carb is this the correct one for a 1972 1300cc dual port engine. My engine seems to be cutting out and difficulty starting since fixing the leak on the petrol tank. Appreciate thoughts on this please. Deb 👍

If it was running ok in the past then can only be something that has changed

Don't know the story of the tank but could crud from it have got in the system? If so a carb clean may fix it.

It's also got a bit cooler now so are your heat risers working? Is choke working? Loads on here about warmth to carbs, Peter's site is well worth a look.

Of all else ok then check for air leaks in manifolds and exhaust

If it was running ok in the past on this carb it suggests it should be alright

Good luck

Since fixing the tank, you may have had dirt or something go down the line to the carb after disturbing the tank and pipe work. I would suggest you clean the carb and check the fuel pump delivery.

Carb— carefully screw in the 2 screws air and fuel counting the exact number of turns from fully in (gently till they stop not hard in) then remove them. This way you can reset them after cleaning by fully in and count the turns back out. Then strip and clean carb.

Fuel pump you need a Fuel safe see through container to put the Outlet pipe in then crank the motor over to see what delivery there is.

Or it may be coincidence the points have gone so a quick tune up may be in order.

That carb is off a 1600tp engine, a1300 would have had a 30 or 31 carb.

Thanks alot all. Waiting for someone to refurb carb and reset because since petrol tank pipe replaced buggy prob having too much fuel now instead of it being starved before.  On wards and upwards before next mot in Feb. So hoping I can eventually attend a few of the gatherings in my buggy in 2020. 👍 Deb

Probably a sticking float. A standard, mechanical fuel pump should give you an issue.
