Possible project/conversion: Stihl FS50E

I got this engine from a rental yard some years ago. It was originally a String trimmer of some kind, though it couldnt have been a very powerful one. It does still run as-is, but I'm considering converting it to run as a glow. I cant find any info on it through stihl or googling the model number. I measures approximately 16cc or .98 cubic inches. (1.100" bore, 1.027" stroke) so I dont think it would be overkill to run as a glow. Anyone have any insight on this little guy?

edit:
The carb that came on this engine is a Teikei from Japan, the numbers stamped on it are NB and 3L. It also has a primer of sorts. Engine (butterfly) side of the carb is 13.85mm, outer diameter of the carb is 6.47mm approximately. This carb has two mixture needles.

I have a Walbro carb thats bigger, but I dont know if either carb will flow enough fuel to run methanol. The Walbro is a WT 26 and doesnt have twin mixture needles. Engine side is 14.28mm, air cleaner side is 7.9mm.
