You are moving along nicely!
I have a carb chart for different temps and elevation.I vote Kohler. No need to tear up a perfectly good sled.
Plus no worries about the aforementioned piston melting due to tuning, you'll have more toys to play with, and since it's 4 stroke, it'll have loads of torque!!!
You wouldn't happen to know the chain pitch on that engine and sled would you?
I wouldn't say people are too scared to make stuff out of round tubing. As someone who went to school for welding, I can safely say that there is a huge learning curve to weld it. Need to keep the angle, stickout, speed all the same to get a nice even bead all around. 6" schedule 40 pipe is one thing to weld, tubing is a whole another animal. Plus square and rectangular tubing is easier to fabricate with if you don't have the tooling.
I cannot wait to see the finished product and watch videos of this thing flying down the road.
I get it, just saying its rare to see a scratch built kart from tubing on the forum.
That's a good thing. IMO, as a Journeyman welder (with a degree, I know, EEK passed many certs) and over 30 years experience.
I get that for some my next statement will cause great anal issues. Doesn't change the fact that cheap azz Harbor Freight wire machines are junk.
This is no offense to you Karl. Quite the contrary, I wish I had the gumption you have. I used to.
Honestly, a man like you could make legit machines with a 110v CC carbon arc box. A torch, whatever it takes.
Over the years I've worked with a few men like you. I was a better welder. I'd trade those skills for the creativity those guys had. Not the paycheck though. Lol.
Bummer that the hydros were already parted off of that thing.
