Trying to figure out what looks to be a carb problem. Mikuni BST34.
Symptoms: When cold, engine starts immediately. Let it run for a while (anywhere from 30 seconds to 10 minutes) and the motor dies. Will not restart. Let is set for a while (an hour) and it starts immediately.
Have taken carb apart and cleaned everything, running thin wire thru the jets. Followed service manual (terrible index) to set carb to spec. That did not help. And when running and revved up, for a bit I could see small amounts of fuel coming out bottom of bowl although I could not see exactly where from.
Latebird suggested elsewhere that I should check the floats to make sure EtOH-containing fuel did not damage them. One does look a little weird. So ... and here's the rant ... I called the Polaris dealer and asked about floats. $75. WTF!? I had just bought a float bowl gasket (not needed) that must have cost about 25 cents to produce for which I paid ... $20!
Question: Where can I get reasonably priced parts, especially floats? Please name a company/website.
Question: Where can I find part numbers so I can determine if things for sale on eBay elsewhere) might work.
