Hi Pitcrew, Well, I'm trying to avoid spending +$300USD on an gauge, therefore I'm trying to find other sources. The problem is that most of the info applies to the two-valves and the info on the 4-valves is much vaguer with a bit of thumb pressure here and moderate pressure there and 3 mm instead of 5mm. Granted, with time and experience I might also go without a gauge and do it with "feel" but when I go 11000rpm on the long straight I'd like to know it's set right. Cheers, /Uffe |
