Finally put mine together the other day.
Ordered a friction drive rear kit (no engine) from staton-inc, called first and talked to david staton to make sure I was getting the right stuff. Had everything in hand 3 days later, took about an hour to install (I was taking my time). Realized the fuel lines were dry rotted within the first 5 miles (fuel lines came with the engine off craigslist, not in the kit) then while replacing the fuel lines took a close look at the primer bulb and realized it was cracked! I had been leaking gas everywhere! So $9 later (2 fuel lines and a primer bulb) and about 5 minutes of tinkering it is back together and working fine. Have 50mi on it so far, which is saying something because I live in Franklin, and everything is within 2 or 3 miles. I intentionally ordered a size larger (1.15" instead of 1") friction drive that david recommended for the 33cc engine, I know it is a bit underpowered but still wanted to be able to cruise at 25-30mph, I am planning on getting a 49cc robin after this 33cc blows up and feel that that would be about the right roller for that engine. Posting pictures here in a little bit, probably putting a longer writeup in another thread/category where it is more appropriate, will link.
PM me if anybody is near franklin and wants to ride the Natchez Trace w/me.
