hello everyone, sorry if its a stupid question, but how easy is it to take out the carburettor and put a new one in, what tools are required, and do you have to have had lots mechanical experience to be able to do it? is it pretty straightforward or is it complicated? thanks guys!

You will need a spanner set, screw drivers, pillars etc. Basic tools.

Remove the air filter

You need to undo the throttle cable, choke cable and fuel pipe from the current carb.

Depending on the carb , theres 2 or 4 nuts around the carb body to undo. Remove the nuts and the carb will slide off the manifold/bolts.

Clean the manifold gasket face,replace with new gasket. Refit the new carb in reverse order of the above.

Haynes manual will explain it all, its not a massive job.

Once fitted, you may need to adjust idle and mixture to get the engine running correctly.

Depending what manifold you have fitted, you may find that you need to tilt the engine foreward to give enough clearance to slid it off the manifold studs.
Thats easy enough though just undo the engine steadies top and bottom of engine.
Also just to add to the above should also be a spring from carb to heat shield will need to unhook.

Hi There,
Changing th carburettor it self is a pretty simple task & is generally straight forward. Just follow a manual & you shouldn't have any problems.
The tricky bit is setting the new carburettor up. getting the mixture right etc. Why are you changing it ?? Normally mini carburettors are pretty bullet proof and don't cause any concerns as they are such a simple design.

hi, i am changing the carburettor as my mini broke last month, the engine would cut out every few minutes or so until it wouldn't start at all, my friend replaced all the ignition components as they weren't in good condition and hoping it would solve the problem, now it seems to be something with the fuel system so he reckons its the carburettor thats the problem. thanks for your help also!

Worth trying if you have a spare carb to hand, but there's precious little you can't fix on one if you're contemplating spending much money on a new one.

Ignition faults tend to be more instant and related to engine speed. Carbs faults tend to be more gradual and load related - e.g. under acceleration or going uphill.
