Checked timing and adjusted....
Bought a great timing light today, it has a digital advance and shows the rpm, and it has a steel clamp instead of plastic.
My old ****ty timing light had a plastic clamp that melted away after hugging the header.
Anyway i first found the correct TDC and then i plugged the vacuum advance and set timing at 10 degrees BTDC, THEN i revved the engine and found the timing come in at 1300-1500 rpm at 36 degrees BTDC.
it didnt like idling at 10 degrees BTDC, ut hooking up the vacuum advance brought it to 25 degrees BTDC, it idles fine.
--Isnt 25 degrees BTDC too much while idling?
--I think going full advance at 1500rpm is too soon because if you rev it quick in neutral i hear some detonation.
What do you think about this?
