i recieved the new jets for the 38 dgas... and while i was waiting i did a bunch of reading on how to read plugs.... more than one article sugested only reading new plugs and not to try to read old plugs... so i bought 4 more plugs and put a new plug in the #2 cylinder with the 150 and 155 main jets.... after running at 3000 rpm for 5-7 minutes i pulled the plugs and tried to read them with a 20 x lighted hand lens.... in both cases the only thing i could tell was that the plugs were alittle hot ( the color change on the ground strap was real close to base ring) and i couldnt tell anything about the mixture (couldnt see any color on the base ring or down toward the base of the ceramic) got any suggestions??? also i couldnt see any deposits on the ceramic

The Gt is still on jackstands until the ventilated rotors and calipers get here this week.... then ill be able to drive it

i noticed a big diffrence in throttle responce from the 142 to the 150 mains... i couldnt tell much diffrence when i installed the 155's
should i go back to the used plug (250 miles) and then run it on the road??

how long should it take to color up a new plug for reading?? i couldnt see hardly anything after five minutes on jackstands

i have a set of platinums i can install... are they easier to read??

Thanks!!
