I have an older FS-66, like from the 1980s. I also have Stihl saws: 009 and 310. I like Stihl
My FS-66 is having issues. It didn't start. I took apart the carb and cleaned it. It had some build up. Got a carb kit that supposedly would fit and hunted down some gaskets that fit. The fuel pump portion seemed to not quite work. One of the flaps that should have opened seemed partially impeded. I resused the old, replaced the float, used carb cleaner, etc. I blew out the pickup hole (from the cylinder) which feeds the fuel pump. Spark looks good. Gap at 25. Air filter is clean. Exhaust looks clear (aired it out). Fuel line seems okay, for if I pressurize the tank (air through fuel line, it just spews the fuel out).
I struggled to get it to start. It was happiest when I pulled the plug, aired out the cylinder and plug, reassembled and immediately pulled the rope to start. I tweaked the L and H adjustments and I was able to get it started and running. It seems to run a little hot. H is at one turn out. L is about 1.25 turns. Starting fluid does not seem to help. It seems to have good compression, but not sure how high it is supposed to be.
I am using the same mix fuel as for my 009 which starts without a hitch. It is not new fuel, but not very old (this summer). It smells okay.
My issue is that it is difficult to start. When it starts, the choke is not on all the way. Most times, it does not want to start. Leave it alone for ahile and try later and your odds go up that it will start.
VERY short on cash, so taking it to the Stihl shop is not an option right now. Pulling my hair out. Any suggestions.
Any suggestions for what I could have missed or what might be needed?
