You might have to make your own after finding TDC on #1. I believe there are a few methods of doing it. One of them is putting something long and thin in #1 and ultra carefully turning the motor until you find the highest point.

Also have you looked at behind the V belt. It was there on my van for some reason. The stuff in front of the V belt in the picture is just to make it easier to do the timing. There was no marking whatsoever in front of the pulley before I put that paint there.

If at first you don't succeed. Build, build again.

Hi

The plastic timing scales often break off. This is a aluminium one from aircooled net.

If your motor has a single vac advance unit its 7.5 BTDC

Yum! Thanks for showing the aluminium timing thing to me. I mean mine is still intact somehow, but that one is much nicer.
My plastic one has chunks ground out of it front and back by the pulley and the fan. I have no idea how. There are also grind marks on some of the tinware. That's why I did the respray recently.

I have to admit, even doign the timing both statically and with a strobe I'm still convinced my timing is off. I dunno anymore.
