"I had some bad gas. drained tank and cleaned. payed a nice amount of money to have carbs cleaned about 6 months ago by a service mechanic. motor bogs down when i go from idle to a plane. its slow to wind up, but once it does its fine. seems to run rough at about 1500 rpm's. pulled carbs off again and cleaned. started the low speed jets at mnfr's recomended setting, slowly turned out about 1.5 more turns while runnung. sounded good. ran okay first time out. next time out was bogging pretty bad. any suggestions as to where on the carbs to look for junk"
