If you get pissed off by it,take the break and come later with clear mind. I had a problem with choke O ring which caused left side to be considerably richer than right , which drove me crazy, I took carburettors apart,cleaned them,checked all the Jets and needles and put them back together around 5-6 rimes, spent 3 weekends doing it, to the point where I did not know what the fuck was I doing any more. Came here and went through shitloads of old threads , was even considering to buy new set of carburettors,"lucky" didn't have the money. Sent from my ONEPLUS A3000 using Tapatalk
