2004 3010 gas. This thing has gotten hard to start when it is cool to cold. I have to choke and grind awhile to start. It acts like it isn’t getting fuel and temperature may or may not have a lot to do with it. Put a new fuel pump and filter on it. Didn’t really help. My question is can this carb drain back or leak down? I see know signs of leaking. And once it starts. It will fire off the rest of the day with just a touch of the key. I did rebuild this carb when i first got it together due to only idling on one cylinder. That took care of that issue and it has started good all summer. Any thoughts or ideas folks.
