Carburetor adjustment

[ice-fishin]

Curious to know if anyone has experience with the following. I have an Eskimo auger with an Emak engine, built in 1996. The auger has run great for years, but now is running very rich. It idles ok, but only runs at half power at full throtle, sucks gas like crazy, and smokes a ton. I've changed the plug. I suspect there is some interal fouling. My next move is to unscrew the high idle adjustment and spray it out with carb cleaner. Here's where I'm stumped...the idle adjustment screws have interlocking tabs that allow you to only adjust each screw one turn....can't turn them far enough to remove them. From what I've read on the internet, the tabs were put in place to keep you from adjusting the carbs to the point that the engine would be out of compliance with California emission standards....which really helps me in Minnesota! Has anyone run into this, and how do you get around this to remove the carb adjustment screws?

Just grab the plastic covers with a pliers and pull them off. The adjustment screws are under there and you will need to get at them to work on the carb. They most likely are just pushed onto splines on the outside of the adjustment screw heads.

Clean your carbs and air filter and use premium gas and synthetic oil. Cleared my jiffy up.

Yes you can pull them off and lean out the high speed adjustment if it is too rich. Thing is the limiter caps are there so the carb can't be adjusted too rich. It could be that the inlet valve(needle and seat)isn't working right. If you can't get it dialed in with the High Speed Mixture screw then a cleaning and kit are next. Check and adjust if need be the lever height, it should be flush with the floor of the body.

Califonia emissions? Guess that's my next ice fishing adventure.

I would try to change your carb gaskets. I had problems with my auger staying running, so I took the carb off and purchased a gasket kit....no more problems and it ran like new again.
