So I got tired of getting yelled at because of the puddle of drool I left on the floor every time I went into the dealership. So I bought a 500i, I have about 8 tanks at most through it. So I’m working in snowy conditions, steep ground and -14 celcous. So I had to slash some trees from around some hydro poles. Just a small clump the mulcher can’t get. Anyway I did 2 poles and was half way threw the 3rd when I noticed a bit of hesitation. It got worse to the point if you hit the trigger she would die. If I pumped the primer it would fire up and run for a bit and die. The saw had some ice build up and a lot of snow on it. I checked the air filter it had some snow, cleaned it. Dumped the fuel out and I saw what looked like 2 bubbles in the fuel filter. I thought maybe that it got water in there so I took off the filter and blew through it to clean it. Then swished the tank out and refilled. It’s seemed ok for a bit then did it again. It’s back in the shops. I’m interested to see what he comes up with. My friend has the same saw, had it for a year in similar conditions, wet snow dry cold snow you name it it’s never missed a beat
