Re: As we are now in lockdown...

I'd love to be in the workshop at home but I'm still out working. Life is so unfair sometimes

Re: engine rebuild won't start

You could have left the dizzy alone and just swapped the leads over opposite what they are. Basically 180 degrees .

Re: 1275 timing marks

i'll hold my hands up and say I've never understood this timing mark stuff. I read the manuals many times over a coffee trying to get my head around it, but am still none the wiser. I was beginning to think it was old age! the way I tend to do it, is get the rotor arm pointing to number 1 plug. put ...

Re: engine

if I run my finger mail over the area there is virtually no resistance/markings. I think the pictures make it look worse than it is.

ok Phil, I think I can manage this.

Re: engine

...some marks on the surfaces.... Exchanging/regrinding the crank, for me, would depend on what you mean exactly, and the dimensions of the crank - ovality, size. The marks may be cleaned up with fine abrasive, or maybe not. I suppose it is better to exchange if you are not sure. i'll get some pict...

Re: engine

cheers as always phil. so I think it's best I exchange the crank for another as there are some marks on the surfaces.

ESM must do an exchange 1275 crank for the midget.

Re: engine

I took it from phil's advice above that to keep the mechanical clutch arrangement, you would need the following
1275 flywheel
1275 clutch (pressure and friction plates)
1275 clutch thrust bearing
1098 clutch fork.

Re: engine

so I use the 1098 fork with a 3 piece 1275 clutch then. Think i'll buy a new clutch for piece of mind. I could put the flywheel on my lathe at work and give it a light skim.

Re: engine

Phil, I already have the following to hand 1275 flywheel.JPG 1275 clutch.JPG whilst were on the subject, this is a picture of one of the bores of the 1275 block. Would you say this looks like it has a sleeve fitted? It measures 70.6mm or there about. That's standard bore size for a mg midget is it n...

Re: engine

Why make it so complicated? It's standard 1275 Midget engine, why not just use a standard Midget 1275 flywheel and the standard Midget 1275 6.5" diaphragm clutch. It works very well in standard form!! That's what we have with our 1380, apart from an uprated driven/centre plate. It's heavy enough to...

Re: engine

Thanks phil. I think the penny has dropped. I already have the 1275 flywheel. I need to find a 1098 clutch cover. The only one I have is on the car.

Re: engine

Also is the dowl you mention?

https://www.moss-europe.co.uk/dowel-clu ... soc=143942

do you machine the 1275 flywheel to accept these dowls and then you can fit the 1098 clutch?

I could then use the mechanical clutch (1098) with a 1275 engine fitted.
