Did search the forum but didn't find exactly. Bike was standing for 3 monthes, today try to start it, but before did some things: replace the spurk plug and check for spark- Ok, replace the fuel to fresh one, clean the air. After a lot of kicks the bike started, wait to warm it (with the choke), closed the choke and the bike stalled. I got to possition that to run it idle without choke i opened the idle screw 5-6 more turns, but with choke running it was too much and have to close it. I know that for some of you the problem is familiar so i have some questions: 1. What happends there? 2. What i need to do to fix it (i do have the manual book)? 3. Can it be fix without removing the carburator? Thanks a lot to all helpers.
