cam timing

Yes you can. You will need to attach a timing disc to the crankshaft so the rad or clutch cover will have to come out. Then set your tappets to the setting for checking the cam timing. I think it's .019". Better yet is to set them .010" wider and use a feeler gauge of that size to feel when it's just nipped. To identify your cam, measure the timing and the lift then compare with the various tables on the matter. If you have a really radical cam, remember that some types are scatter cams so will have a different timing on each cylinder. I've never worked with those though.

Thanks for your reply.

the cam should be a 266 but the thing is that when the engine was rebuilt the guy fitted a 276 by mistake. after running in i brought it back to him and left it for a couple of days as he said he'd fit the

266 for free as it was his mistake. it's just that i'm not convinced ge changed it as the engine doesn't seem to have anything below 2500 rpm and only reallt picksup just over 3000. why should i remove the cluch cover if i remove the rad?

thanks again

The cam position may also be out which does affect the performance.

When checking you may also want to note the timing position - and if necessary index it.

When a cam has been ground sometimes it does not position itself correctly with the standard timing gear and a variable camshaft gear has to be used.

These specification should be supplied with the cam grind.

As others have noted and using a degree wheel the cam should start opening at X degree and close at Y degree with ZZZ lift.

This is a reference which may help your understanding although not for the mini but same principle.

You remove the rad OR clutch cover. To use a timing disc, you need access to one end of the crank.
