Kohler CH22 starving for gas

Some on this forum will disagree, but if Op doesn't want to pay for an oem carb, he can always try amazon and ebay for about $15. If it works, then bingo, if it doesn't you have lost little.
I know Chinesium carbs are controversial on this site, but 20 out of the last 20 I tried worked fine. Others have had a different experience, true enough. But if price is a big concern for Op, then this is merely an option for OP, and no one else!

For the most part, the Chinese carbs have been fine for the last several years. I used to buy the cheapest listing, had issues in the past. Now I buy one that is say $10-15 bucks more than the cheapest listing. No issues since. I still go through each one looking for deficiencies. Float heigh set proper and so on.

I went back through most of the posts, and this is pointing toward the fuel tank having to be removed emptied, then flushed out and left sit to dry for a couple of days. While it is drying, go back through the lines, elbows and pick up tubes.

You are chasing a globule of trash and bad fuel likely mixed with water. This stuff moves at random at the bottom of the fuel tank and will drive you crazy.

The other possibility is a cracked plastic pickup tube. Think of a bent/cracked defective straw when you are trying to drink from a soda cup. Cracks in plastic tubing expand with time and heat on riders.
