Is the timing set correctly? Blocked carb?

Eliminate those two possibilities and see what your outcome is

Edit: I noticed ‘new carb’ was this new carb an OEM carb or $50 aftermarket eBay carb? If the latter then there lies your issue.

Also, confirm that your pilot mixture is set correctly.

first of welcome to the site
as for info/help
odds are if fuel is overflowing out of carb, its very possible its also filled your motor with fuel too< so check oil for smell of fuel in it
so odds are if carb is NOT set right this could be the issue too
and I second, many NONE OEM carbs are JUNK,hit and miss, some get lucky many don't


and you didn;t mention WHY the new piston and rings were installed? maybe there is a reason for that that is also causing the issue?

Okay I didn't know I had to set the timing I was informed that you didn't have to on the model on the Rancher with that style motor. Also I don't see where I can adjust the timing on this motor. I put a new piston because it was scarred up the sides of it when I put the Rings I noticed that. but it ran before I rode it already. Does anybody know the settings for the air-fuel mixture on the carb.

Make sure the valves are adjusted properly and fix that flooding carb before attempting to start the motor. I assume you honed the cylinder, correct? If you have flooded the cylinder with gas while trying to start it, remove the spark plug and pour some motor oil in the cylinder to relubricate the bore & piston and turn the motor over several times. Do not wash the cylinder down with a flooding carb again, it causes a lot of damage to your new parts. Let us know if you have any questions.

I just reread your 1st post. You mentioned that you put a new carb on the motor... That is a BIG RED FLAG! if that is a new OEM Honda carb then the tank is probably supplying grit to it, causing it to flood the float bowl. Clean the tank, petcock and fuel line and carb to fix that.

But if that is an aftermarket carb (from fLeebay or Amazon?) it is useless china garbage and you'll need to put a good clean OEM carb on it to fix it.
