Talk here about 2 stroke timing made me think of checking the HF. Took a bit of doing but this one has about 27 degrees of advance. It didn't change with rpm and I left it alone.
Looking at the engine with a thought of more power, the carb seems to be real small. Probably great for the rated hp and rpm though.
I am not kicking about the power, it seems like an old Honda 90 untill about 35 mph where it runs out of steam, Maybe the small carb is why.
With the disconnected gov, more open muffler and different air cleaner mesh, I think I am around 3.5 hp.
The exhaust port looks like it could be opened and probably the intake too.
Anybody do mods to one yet? Am thinking a bigger carb and some porting would add another hp.
I have no idea what rpm this thing is doing, am imagining around 5000 it is flat out.
