Hi all,
First time post, google found this fantastic thread for me, unfortunately I'd have to take time off work to read it all!! I have a Pioneer Holiday 1100W saw that won't run properly.
The saw used to be my Dad's but it started to give trouble 10 years ago or more so he bought a new one. It seemed to cut okay, but once it got hot, it would quit. Fast forward 10 years when I decided to either get it running, or get rid of it. I got it going and it cut great for a couple hours, I had never had that saw run better and was damn proud! Next time I tried it still ran good, but started to cut out after several long cuts. Some fuel was bubbling from the vent holes in the gas cap so I wondered if the saw was running hot and too much heat was getting to the fuel. Temp this time was 10C or so versus 0C the first time. I took the saw mostly apart thinking the cooling fins were partially blocked. I cleaned everything up, put it back together and looked up how to adjust the carb, in case it had been running on the lean side. This is when the trouble started.
It will idle fine, but after 30 seconds or so at full throttle, it cuts out as if the fuel was shut off. It will still idle, but opening the throttle kills it. If I hold the choke 3/4 closed, I can get it up to speed (most of the way) and then opening the choke will have it running full speed, but only for a half second before it cuts out. I have had the carb apart with no change from before.
Frustrating because I should be cutting, not fixing!! It's kind of neat using a saw that is more than 10 years older than I, so I'd rather not buy something newer but it may come to that.
Thanks in advance for any insight!
