Convert, but keep running on glow fuel.
Running gasoline requires larger cooling fins. Due to the very high specific power, you would need to run at least 10% oil as well, mainly castor, there are good castor based cart oils around) You need to provide good cooling ducts and baffling/jacketing as well.
BTW, the crank pin cannot be used for needle roller bearings. The material is too soft at HB30-HB40. Needle bearings need HB60 or more (glass hard, cannot be filed)
I agree. A cool setup would be to convert it to a Walbro carb, CDI ignition with a 1/4 x 32 spark plug, and run it on Methanol/oil mix at the factory recommended ratio. Use a Walbro WT-499 carb. It is a good size for this size engine, and is made for use with methanol so it will flow enough fuel and have methanol resistant materials.
Then go "spank" some of the guys running DLE 20's. (Don't tell them you're running methanol, just to add insult to injury....)
