When you say towing 300 lbs do you mean in addition to bike and rider weight?
Because if you do I would not consider that normal use, that is a load. I don't know what type terrain you're going to cover but besides needing some phenomenal brakes you might find a 35cc a bit underpowered.
I have that same setup and for me at 190 lbs plus bike, no other load, I have to pedal to get rolling to 10 mph not to really bog and labor the engine.
The Honda GHX50 has a 3 shoe clutch and obviously more power.
Another substantial issue with such a load besides the clutch slipping will be the spindle slipping on the tire.
BTW, with the drive you mentioned, I'm curious how ya going to get a 7/8" spindle when the smallest they now have is 1"?
I believe but am not positive staton offered a 7/8. The place I purchased from does not. I am going to get a 1.5 and a 1" for starts. I am planning on going slowly in increments with the weights and will go front and rear if I have to. an empty trailer I can personally pull pretty fast and I have pulled a washing machine full size with a stainless drum, and 200 pounds of misc on a trailer this past summer with 1 or two flats. I found that tires want to go flat or look flat under such pressure.. Finally my derailer cracked off the aluminum frame (of all things)!!! I can still tow with the Gary Fisher but must attempt an aluminum repair of the derailer and do an overhaul of the entire bike first. Looks loke the GHX50 is a top contender at the moment. I like this forum a lot and plan on showiing you what a bike can do for people when your down and out and innovated. I won't be down and out for long. I might be the new UPS in town!
Thanks for the tip!!
