Re: engine rebuild won't start

Correct in that the dizzy has an offset key at the bottom to ensure that it is correctly aligned with the distributer drive shaft which runs off the camshaft. But if the distributer drive shaft has not been fitted as per the manual no matter how hard you try the ignition setting will not be correct....

Re: 1275 exhaust manifold gasket

It is Saturday - I would order on line and get it delivered soonest. From their front page they appear to be still operating and dispatching parts.

Can you not use your old gasket? Smearing in grease usually softens up the manifold gasket enabling it to be reused.

Re: 1275 exhaust manifold gasket

When you fit a new manifold gasket smear it with grease - it will last longer and it will be reusable.

Re: engine rebuild won't start

So long as you fitted the timing gear marks in line when you assembled the engine you will be ok as that is the basic setting. So I would advise that you do not do anything about the timing gear marks at the moment. Set the distributer drive as per the manual, fit the distributer and then try and st...

Re: engine rebuild won't start

I suspect that you have the ignition timing way out. Pull the distributer and check the distributor drive is in its right position. See BMC wksp man section A.A. 28 for the correct fitting procedure. Note: The procedure requires No: 4 cylinder to be at TDC on its compression stroke. Take care not to...

Re: jacking beam

Les It is the actual contact area between the chassis leg and lifting beam pad when the car is being lifted that concerns me! You are right in that the jack should roll forwards or backwards to compensate for the lifting arc of the jack but it will not compensate for the movement arc of the chassis ...

Re: jacking beam

Very good but - and this is no criticism but hopefully constructive suggestions...…. As you jack the car up the contact between the jacking beam chassis leg pads and the chassis leg is going to get less as they are both moving in different arcs. The contact could reduce to the point where the beam s...

Re: 1275 timing marks

One hole is just behind the thermostat housing the other hole is at the rear of the head by the heater tap. If you do not have the corresponding threaded holes in the block then there is noth...

Re: 1275 timing marks

Les The valves in the 940 head (top) have been replaced with larger items so should not be used as a comparison. The valves in the 12G185 head (bottom) have the same head size 1.4" inlet & 1 5/32" exhaust as those in a standard Cooper S / 1275GT 12G1805 head. The valve stems of the valves fitted to ...

Re: 1275 timing marks

Non of the in line engines had the additional stud (at the rear) and the bolt (at the front). It is a common conversion to fit the additional stud and bolt. The 940 cylinder head even without the stud and bolt has the casting boss's inside the head which can be drilled through. Most conversions to 1...

Re: 1275 timing marks

With everything right the plugs should be a nice digestive biscuit brown.

Over advancing the ignition causes pinking or pre-ignition.

Excessive retarding of the ignition can lead to melted pistons.

There is a fine balance to be struck between advance and retard.

Re: 1275 timing marks

As I have already said - the setting of the timing marks is only the beginning. Obtaining the smoothest running and best performance overtakes getting the timing marks to align as per the manual. Hopefully we shall see a day when we can all get back to normal - whatever normal is. Take care and keep...

Re: 1275 timing marks

So long as you have identified TDC on the compression stroke of No: 1 cylinder the timing mark (both pulley & timing cover) can be placed where you find them most convenient to view. Placing the cross on the RDC mark is a good idea, saves any confusion. As the engine turns clockwise the actual firin...

Re: 1953 (March) Series II Restoration

I have seen the lower heater hose put through the hole in the O/S engine mount tower but never through the large hole in the Ser 2 front engine plate.

I would PM Declan for details of and the availability of the restrictor.

Re: 1275 timing marks

If your engine is running the timing cannot be 'a country mile out'...….
Just set the timing so as to get the engine running sweetly and not pinking. That is all you can do. The timing settings are there as a base line - final setting has be done by road testing or using a rolling road.

Re: 1953 (March) Series II Restoration

Looking good - well done 8) A slight variance to later 'A' Series engines is that your front engine plate has a large hole in it positioned under the dynamo. The hole was deleted on later models. After all that work I would recommend that you fit the restrictor to the oil filter. The restrictor shou...

Re: 1275 timing marks

The adjuster on the distributer is for the very fine adjustment of the timing therefore you will not feel or see a discernable difference in the timing other than by using a timing light with the engine running.
Half a turn will not make much difference.

Re: Plug gap

It depend upon the coil fitted. What do the fitting instructions say? If you do not have the instructions you may be able to find them on the web. I would set plug gaps to 0.025" - see how it runs and then set to 0.030" and see if there is any improvement. If there is an improvement leave at 0.030"....
