Hi.

Recently my mini has been missing/ stuttering towards the higher revs in every gear. I have checked the timing and it is ok now, any other ideas?

I am noticing quite a lot of bubbles floating up through the filter towards the carb, valve clearances are all ok so the fuel pump sounds like the most likely thing.

Thanks

My car was misfiring for 3 weeks and I couldn't work out the problem. I changed the points thursday as I saw they were a bit pitted and it's run pefect ever since. Worth a look?
