So I searched, did not find a pertinent thread.
Anyways -
My 660's had been sitting empty for a while. Both had been getting a little use last winter. Bought a new gallon of HO gas, made the 40:1 mix and 660a fired up. Sthil FS45? weedwacker fired up on same mix.
Short break for travel, 3 weeks later, bought a new gallon of HO gas, made another 40:1 mix (Bailey's synthetic oil) tried 660b. Darn near pulled my arm off, no fire. Tried the same mix on 660a - no fire and weedwacker, no fire at all.
Gas was bought at my local station I've been getting saw gas from it for years, but I suspect that I HAD been lucky before.
Bought new plugs and a $8 quart of 1:50 fuel at the local Stihl dealer. Using that and an appropriate shot of SeaFoam 660a runs well, 660b fires and dies. Both had run like a raped ape at freezing temps last winter, now it's 90 degrees F and 100% humidity. Both saws pump fuel, 660B compression is 145. Both at 1 turn out for low and high.
So - three questions -
How long should it take to get the carb "self cleaned" on 660b?
Do I need one of you to walk me thru a carb rebuild?
Has anyone else experienced this due to bad gas?
thanks in advance
