Honda EU2000i pilot screw
I've got a surging idle problem with one of my EU200i's and done all the standard cleaning several times. I'm absolutely sure it's the carb because I've got a separate brand new carb that runs both units perfectly, and this dirty(?) carb does the same surging idle issue on both units.
The main jet and pilot jets are completely clean, carb is getting plenty of gas. Runs fine on on full mode (eco off). It was run in a very dusty environment for a couple weeks and when it ran dry I suspect it sucked up lots of gunk at the bottom of the tank. As I said I've fully cleaned and rebuilt it several times over, the only thing I can figure is that there's gunk I can't get to behind the pilot screw, the one that has the limiter cap on it. The manual explains the process for breaking off that limiter cap, removing the broken screw and installing a new screw and cap
(and notes that it's illegal to tamper with it). However I'm confused by the instructions. It says remove screw after it's been broken off but I don't see how that can happen if it's broken off halfway inside at the break point.
Has anyone removed that screw before? Any experience from someone who's replaced that screw would be helpful. Does it just fall out?
