While working on a different ski (ski #2) that doesn't have this same hard start issue as the aforementioned jetski of this thread, I noticed some things. Went to clean ski #2's carbs, especially the low speed circuit and pilot jet as it was having problems idling. I took apart the jet side of the carbs, pulled jets out, cleaned, etc. I noticed that the springs for the needle valves were shiny silver (i think platinum). This is different from the 80 gram dark black spring I believe these 96 GTI 717's are supposed to have. I never took the springs out to measure length, but I did check popoff. Both carbs for ski #2 were very close. #2 PTO carb was 33-34psi. #2 MAG carb was 34-35psi. Ski #2 starts up everytime, never has problems. It didn't seem like there was any difference at all in the streams of brake clean spray flowing through the jets and carb holes while cleaning each set of carbs (ski #1 vs ski #2)
I think this may indicate my issue might be with the large variance in popoff pressure between the two carbs for ski #1. Currently I am still waiting on parts for ski #1. current popoff: ski #1 PTO carb 49-50psi. ski #1 MAG carb 39-41psi.
