So I picked up a used Dolmar 6400 from a member here about a month ago. It runs really good. Starts idles cuts great.
The issue I'm having is when I set the saw down for a few minutes it doesn't want to start. Takes me quite a few pulls.
So I decided to inspect it a bit. Compression was at 195 and it's been sitting for a couple weeks. Pulled the muffler and found a couple cracks in it where the bolts go. One of the front bracket nuts inside the muffler pulled right out. Which effectively made it a dual port!![emoji12]
I wanted to get a pre cat muffler anyways so if anyone has one let me know.
The piston and cylinder look great so that's good. Then I started to look at the carb and when I touched the gas line it squirted fuel. I pulled it off and there was a gush of fuel under pretty good pressure. Saw was inside and had not been run. Tank was 1/3 full. I opened gas cap and there was quite a lot of pressure.
Does the tank vent only allow fresh air into the tank or is it supposed to prevent pressure build up as well?
Could this be causing my saw to flood making it hard to start?
Thanks.
