I agree..
I just came from my starting the engine and I think i discover the problem..
I found a lot of bubbles from the small line from the diafraghan to the carburetor.... I think this is a major problem. thats why i have this changes in the rpm in iddle... what do you think guys?? i replace the line to make sure the line wasn't broken...
I think i have to send the engine to YS!!!
Any suggestions
