I have a 1977 Puch maxi Newport. I’ve messed with it a lot over the past couple years. Put in a 70cc low comp treats kit, 15mm carb, boss pipe(I understand this isn’t the best pipe), cleaned up bearings, new air filter, set gearing to 16 40 for a more comfortable top end. I set my timing using a light to 16-17 degrees before TDC.
So I’m having trouble with the clutch where it revs up a little too high to start going and it’s pretty slow to accelerate from the stop. Not bad but I think it could be better. It engages fully around 25 mph and goes up to around 40. At one point I had blue springs in and it felt pretty good. It didn’t rev so hard to get going. It was more gradual. But I wanted to keep adjusting so I use ESO springs and have tried many times with super stiffy and turning the screws various amounts. Now it doesn’t feel so good. Just seems like something that I’m not thinking of is impacting performance. Any advice? (edited)
