Picked up my new to me Wee strom, and rode it for an hour. It starts and runs fine, but after a while it develops a splutter that slowly gets worse while cruising.
At first it feel like a small hiccup, then after a while it feels very jittery and is not firing correctly. If I wind on the throttle it has a hesitation before picking up it's skirt and blasting off. And if I let off the throttle it gives a little buck as if it ran better for just a fraction of a second.
When I pull the clutch in it stalls.
When I let it sit off for a a few minutes, all the syptoms disappear.
I am 90% sure it's a blocked air vent, but the fact it can still deliver good performance when you wind on the throttle has me that 10% unsure.
