MG Midget and Sprite Technical - new timing marks

Could someone post a photo of a successful alternative timing marks arrangement. Perhaps something on top of the pulley with a little bit of angled metal screwed to the chain casing.

Many thanks

You can paint a line on the shoulder of the timing cover (plugs side) and on the pulley. Somewhere you can see fairly easily.

The difficult bit is finding cyl. 1 top dead centre. Unless you just get the marks at the bottom lined up, and trust them.

When Rivergate rebuilt my engine, they fabbed a piece of sheet metal that attaches under one of the bolts that holds on the timing chain cover, then comes out, over and is angled to a point. They cut four kerfs across the harmonic, one for 0 degrees (TDC) and one each for 10, 20, and 30 degrees BTDC. Works great, especially if you have a timing light with variable advance.

I am a bit embarrassed to show this.

I am sure all the grown ups will go "TUT TUT TUT".

I had no identifiable timing marks at all on my timing cover. So when I had the head off and was easily able to establish TDC. I painted the 2 white marks onto the timing cover. The blob is TDC + or - gawd knows what, and the straight white line is my 7° mark. The red arrow just about points out the notch on the pulley. Naturally one needs prior knowledge as to exactly where to stand and gaze in order to accurately line the marks up.

I stuck with tradition and used the same touch up can of paint - Triumph Herald, Old English White, that I have used since 1968 for painting timing marks.

It works for me.

When I had my engine balanced they could not balance the damper so they gave me one off a mini. So the marks on the cover did not match the one on the damper When timing in the cam I had to find TDC so at the same time I marked the timing cover with a white paint mark.Seams to work ok.

i just set it up right
made a smal dent in the cover with hamer and screwdriver
and made a coresponding slot in the pully with a hacksaw

bit of white paint on both and there you have it!

OK, I went out and took a picture of the Rivergate timing marks.

Mine looks a bit like David's but I don't have a photo of it yet. I made it from a piece of s/s scrap sheet (supplied by someone here a long time ago) and secured it on two existing fastening holes on the timing cover / front plate. I points accurately to TDC but I'll 100% check it when I next have the head off and cut it to adjust if necessary.

Thanks for all the responses

I think I will try for a bent piece of metal fixed to the timing cover. I bit of trial and error and I should get it about right. I bet I could work out my own BTDC gauge and stick it on with a bit of glue.

Very short self tapping screws should avoid a clash with the timing chain and lots of gasket sealer to avoid any leaks.

Cheers

I believe that it is Jeff from Advanced Distributors in Minnesota who supplies a piece of bent wire that goes under one of the timing chain cover bolts and ends in a pointer over the damper. He includes in the kit a piece of metallic tape with degree markings, although I do not recall the range. He is fairly active on this BBS in the TD arena. ISTR the price is very reasonable.
