Drove the 914 to turkey time yesterday, about 50 miles of backroads. Seemed to be runnin' about normal with the usual symphony of only-occasional random backfires and pops. It was, of course, ridiculously fun.
Car sat til I left around 10 PM, and by then it was around 40 degrees outside. Lots of popping and stuttering at part throttle. Full throttle and it was the usual fun excitement. The ride home on the freeway was unpleasant because the 2.7L doesn't need much throttle to keep my little car moving. Could this just be temperature related? Idle jets sized for Los Angeles (where I bought it.)? Otherwise I assume I'm looking at checking for gunk in the idle jets, I assume. This is my first carbed porsche, so I guess it is time to really "grok" them. Is there an obvious "start here carb newbie" direction? Book and/or web site? Googling turns up tons and tons of random stuff. Thanks. |

I could be wrong, but I don't think being 300 miles north of LA is gonna affect the carb jetting. Generally speaking, altitude is measured in feet above sea level, not in miles north (or south) of the place where the jetting was done. Of course, looking at a globe could be confusing, what with north being up and all.
