 My 74 JH seems to have come with a single grove crank pulley and four timing marks on the front cover. I assume them stock.

But, Mark emailed me and reminded me that if this type of pulley is placed on a newer engine the timing will be 10 degrees off. And, if the timing was 10 degrees off, well, wouldn't that make setting the valve timing up difficult? just wondering as I am having difficulty starting mine. Ignition timing seems right, valve timing was right, but she coughs and spits out of both ends telling me the engine is not timed right.....

What serial number engines did this switch take place on?My car is a 74, will check engine number.

I've got to do more investigation, it could be it jumped time (ignition or valve timing) on the first few cranks and it now badly out of sorts.
