Morris Minor Owners Club

Can we see a picture of the plate in question?

The web site works fine for me, no ads either.

The Machine Mart MIG welders have a good reputation, I have one and find it suitable for work on my Morris (and other jobs)

Have you confirmed that the carburetor float and needle are in good order? It does sound like you are getting too much fuel at tickover.

Sharp chisel should do it, or file their heads off (ouch!)

Make sure you take off and retain the engine number plate, often lost when the block is skimmed.

SU carburetors do not have accelerator pumps, so operating the throttle pedal will have no effect.

Hope this works

I think you need to check the water pump, make sure the impeller hasn't become detached. Minors are very overcooled so I doubt the extra fan blade would make much difference.

OK, if the light is going out the dynamo (or alternator) is producing some charge. A competent garage would be able to check the output and pinpoint the problem. A picture of the engine bay would show us what system you have.

Clearly the battery is not charging, so the fault would be with the dynamo, regulator or alternator if fitted. Does the ignition light go out once the car is running?

Be aware that the cheap replacement electronic distributors can be very poor quality, you do get what you pay for.

If you can't lock the wheels when you stamp on the brakes there is something wrong.

Not expensive, £10 from eBay https://www.ebay.co.uk/itm/182856816556?itmmeta=01HWCKJV63TNXN7XW4KWPBMPMT&hash=item2a931d97ac:g:~sYAAOSwkNZUhEWA&itmprp=enc%3AAQAJAAAAwA4FT3AOLfsl7%2B4bCxM80%2Bb5d1PrX1L55TC2hU0rAOJZaTAVFIxHJWnWIxJWjAPCVd7bqGW7Dg00viNEhlYrY30d3FndFGldQaw80dpy6E2kuzaJF6XxZ0nOWHTz...

Or do a compression check, no dismantling required.
