My 1978 Puch Newport L seems underpowered. It's the 2 hp version, and in comparison, my 2hp ZA50 Newport II has significantly more power and speed. I expect some better acceleration, having two gears, but not this much. My E50 will barely do 25 mph top. It will barely climb the hill to my house at 10 mph, and if I have to stop at the stop sign half way up, forget it. It seems to run well, but I expected more from it stock.
Bone stock E50, 1950 miles. Carb thoroughly soaked clean. Exhaust cleaned with oven cleaner, but it could use another treatment when the weather warms up.
14 mm intake. 16/45 gears. It HAS a head gasket.
Carburetor is genuine Bing. 1/12/316 #64 jet, 2.12 atomizer, needle clip on bottom notch (raising needle highest).
Wiki shows this carb is for a Magnum XK 2hp, does this matter? Is the needle clip position wrong causing it to run rich? Should I eliminate the head gasket?
How can I squeeze a little more out of this, without changing exhaust? I really like how quiet it is.
