Excellent post pau 13. I can imagine the rubbery tip on the viton needles could pose their own problems and be more prone to jamming. I thought 95 was enough but I will get 98 next time, especially after the point you made about stability over time. I ran a Ryobi 31cc 2 stroke powered bike on Shell Optimax when it first came out about 2000 and noticed the performance boost immediately.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
