1978 - Puch probably Still has Points and NOT the newer Electronic Ignition. So!, do You Know what that Means?
It Means that You have to get out the Dial Indicater, and a Degree Wheel and Set the Points and the Timing. But, You also need to Clean the Carb and Reset the Idle adjustment.
If by Chance, this Little guy has Electronic Ignition, then You'll Probably need a New Ignition Box, and which case I sugjest You look on the Box where the Spark Plug wire Comes from for a manufacture name and then look up the Company on the Web.
A lot of those were Universal and they used the Same unit on many Differant Brand Bikes. If it has a Coil with two small wires, Besides the Plug wire, then chances are you have the Points System, which means Referr to the top.
If you don't understand what I'm Talking about, then I sugest Finding the Tune Up Spec's, ( On the Web, or at the Library ) and Take it to a good bike shop where the mechanic has Used these tools before. I am a certified Motorcycle Tech/Engineer and I raced Motocross in the Early 1970's, and I own a
"1965 Sears Allstate, Puch Sabre 50", Old, But Quick!
Oh!, By the way I'm 6' 2" Tall and 220 Lbs., Your Not to Big.
You Just need a Liitle bit of Performance Tune Up, I suggest You Try the "UK" sites for Hi-Perfomance Carb, and or Exhaust, they have a Moped Racing Sight that can help, and the Exhaust, would be the first thing I would Change, They have these little Guys doing over 100 Mph over in Europe and Japan.
I knew a Guy here in the States that Built a "Honda QA 50" to do over 110 Mph, his biggest complant was the frame Flexing!!!
We had a "1962 Puch Moped" doing 55 Mph with a two speed trans. and a stock engine. It's all in the Tunning.
