ROTAX 185cc (Lazair Ultralight Usage) CARBURETOR PROBLEMS 

(1) Low Speed Problem -Possible crack in carburetor housing low speed passage due to idle mixture needle being forced against the seat.  
 

The taper on the low speed mixture needle is very slight, therefore it is very easy to crack the housing if the needle is forced into the seat passage with excessive force. When removing the welch plug covering the low speed circuit DON'T use a drill to drill the removal hole, you could go through and damage the casting. 
Use a PIN Vice.
   

(2) Choke Over center Pin -falling through into the air­horn area and going through the engine.    

Correction Procedure  -

Take an ice pick or something sharp and try to push the pin through the casting and into the air horn. If its tight 0 worry.If its loose remove and peen over the outer end slightly add a little epoxy and re-install. 

Loctite Loc- weld Part # 14600 is Push  end of pin what we use. We have 5 cases of this  direction shown if problem to date and considerable loose see text. damage  occurred each time. 

(3) Decompression Valve-If the valve has a green plastic covering the outer end remove the end (side cutters work well), check pin and metal end to see if they are secure. 

If the metal end and the pin are loose peen slightly and epoxy ,(We again use the Loc-tite Loc-weld). Its a good idea to epoxy it anyway even if its not loose. If the pin does come loose it most likely will take a chunk out of the piston. Later type valves have been checked at the factory for looseness but have not been epoxied.
