I have a 1961 4-door with a '73 Midget engine and 'box. It has an Hif 6/44 SU (Needle unknown) on an MG Metro heated inlet manifold, and a 1 3/8" lcb exhaust manifold exiting into a 1 5/8" 2 box exhaust. As far as I know the camshaft, stamped what appears to be 1 M 73 on the nose, is standard Midget.

I have heard that an lcb attached to a standard engine with a standard cam can be more of a hinderance than an asset and I'm also worried that the carb might be too big.

It has a fairly lumpy tickover and a smelly exhaust, although the plugs are a decent colour.

What are the best and cheapest (!) changes I can make to make everything better?

The standard 275cc MG Midget camshaft is not stamped on the nose so I would suggest it is not standard.
The engine set up described above is not under or over excessive in fact a most common arrangement.
I would also suggest that you get the car on a rolling road and get it set up properly.

Thanks for those words of comfort Phil!

However, at the moment I'm not prepared to remove the camshaft to identify it, given it's probably got a spider drive.

Could I attach a circular protractor to the front pulley to work out the cam timing as I don't want to take the timing case off (again)?

Yes, you can but the ideal check would involve a dial gauge, to accurately set the TDC and to detect the initial/final valve lift, for a good degree of precision.

Thanks. I'll get round to it one day!
