Nice job on the resto and looks like you have a great workshop.
As to what it is to begin with I would hazard a guess saying its early 70s since you have the flass fuel bowl and updraught carby, since the output haft is fairly small I would be guessing at 2-4 hp as my 5hp one has a larger diameter output shaft and my 3hp has the same as what you have. Cheers Joe.
