Previous engine was a 1776 w/ 110 Engle cam. Dual Kadrons. SVDA dizzie. Engine was a piece of rubbish poorly built by local VW "performance" shop (VW Paradise, San Marcos, well-known to local old timers as purveyor of crap engines). It blew up about 5,000 miles into its life.
New engine is stock Mexican (Puebla factory) 1600DP w/ stock cam, new 34 PICT-3, same SVDA dizzie. Proper carburation adjusting ongoing.
In both cases, dizzie adjusted to full advance (42 degrees @ 3700 rpm per John at aircooled.net).
My main impression is that the new engine is just less unpredictable than the old. With the old engine I never knew how it was going to run. The second impression is that the new engine has less torque in the low end (2000 to 2500 rpm) than the old. Need to rev higher before upshifting when climbing hills than I needed to with the old.
