Thanks Dan. I suspect you're correct about warming up the cats quickly.
The logic of "zinging" to 2000rpm to build up
oil pressure quickly doesn't sit well with me....that sounds like a cross your fingers and hope for the best strategy.
My '76 Alfa twin cam always starts from cold easily (never use choke) and runs cleanly, and I hold it at around 1000rpm on the hand throttle while I'm buckling up.
Pressure comes up quickly, but no doubt its emissions are crap
As far as priming the carbies when it's been sitting for a few weeks - as mine does - that's probably a good idea as it would save the starter motor ....but then it's nearly 40 years old and the starter hasn't suffered noticeably so far. The
oil pressure DOES come up on the gauge though as I'm cranking it over.
Cheers,
Glen
