Powersmart DB7659-22 Hunting/surging
I don't normally touch these big box blowers but I was at a guys house who offered to sell me this 2015 Powersmart 208cc 22" #DB7659 two stage snowblower for $50, he said he could never get it to run right and it chews up the auger belt ever time he used it. Well I figured out the belt problem right away, the pulleys did not line up. Spacers were put in the wrong place, I assume the factory made this mistake. The surging or hunting I have read is a commen problem with these LCT engines. I pulled the carb and fully took it apart and cleaed it, put it back on and that helped with the hunting/surging and will run the engine smooth now with chock fully on. Threre is No throttle and NO adjustment screws on the carb, I put in a new sparkplug and made sure it was gapped correctly, I checked the govern set up and it all matches the manual but it still surges/hunts and only runs smoth with chock on.
So, with all that said....What do you think of drilling out the jet a little bit. Do you guys think that would help with this hunting problem. This machine is basically new, used only a few times...Sad it's having this many problem...But I would like to fix it, any help would be appreciated.
