I have a low hours Robin Suburu EX21 that does not want to idle. It fights to stay running then dies. The fuel seems to be good. Good compression. I replaced the plug. Any suggestions?
Well it works perfect now. Removed carb, cleaned jets, soaked in cleaning solution. Does anyone know what the black adjustment on the back of the carb just under the fuel line is for? I cant find any reference to it. I assume it is the mixture. What is the procedure for adjusting?
