Let me start by saying thanks in advance. My Dolmar 5100 quit and I am struggling to diagnose. I have been told a tank vent issue and am going to take it to the dealer but they are not close and lack what I would call quality service. So, I thought I would start here.
I pulled it out Friday to do some limbing and small bucking. It started 4th pull after 3 month lay off. Cut for about 20 minutes. Turned it off to clear up the brush pile I had created. About 30 minutes later went to start it and it would not run. Seemed to flood out after just a couple of pulls. Fuel out of the muffler real quick. I pulled the plug to let it evaporate. Put a new plug in just in case. Let is rest 2 hours. Got out the other saw. Tried again and the same thing happened.
I have never touched the carb adjustments since i got it from the dealer. They were on the stops when I looked. Little plastic pieces. One red and one white where turned to where they hit the other adjust ment screw. White over and red under I believe.
Run Stihl oil. 93 octane gas that I bet will have ethanol in it. Can't get much else around here. Could the ethanol eat the seals in the carb, especailly the diaphragm? It's a lot of gas quick but none leaks around at the carb.
I bought the saw new 18 months ago or so. No telling how long they had it. Not a high traffic saw. Dealer support for anything other than Stihl lacks around here.
Any help would be appreciated! Thanks.
