I acquired a new carryover 2012 Dolmar PS-7910 in 2018. I’ve put about 10 tanks of premium fuel through it, enjoyed every minute of its smooth operation cutting a lot of birch trees (hot knife through butter), then it sat in the shop for about 8-9 months. I had Seafoam in the gas, but didn’t start it up and run it for the past 6 months. It’s now hard to start, runs like crud, eventually runs out of fuel, dies, and produces a white tipped spark plug. I had a local shop clean the carb, but that did not help. I’d appreciate any advice you may have.
