My Dolmar 5100 just died on me the other day. I was cutting with it when it started idling VERY high, like it was running out of gas, but it wasn't? I put gas in it and it won't even fire? I took the fuel filter off and took a air compressor to it and blew it clean. What should I look for to figure out this issue?
Chainsaw quit on me?

Sounds like air leak, have it checked. It can fubar the saw if you keep running it. We can tell you how.

I only ran it a minute if that. If I put gas in the carb it will fire.

Fuel line failure? Pulse line failure?
Where is this pulse line? I was in the process of taking off the carb, but I am nervous about getting it put back together with all the little parts and never having tore into a chainsaw carb before....let alone a Dolmar?

Do not try and run it! You need to find the source of the air leak.
Replacing the fuel and impulse lines aren't hard. Go to you tube and find a video on your model.

as said above, prob best to have someone, not necessarily a dealer (unless under warranty), check for air leaks. could be an easy fix for you, or it could be something more involved...

YouTube vids for any chainsaw carb should get you in the right direction.

Take the muffler off and have a peek at the scoring on your cylinder.
Thanks for the info. Is the pulse line and the gas line the same thing?

How old is the saw?
When was the last time when run good and for how long?

Saw is about 7 years old. Has always ran great and has ran good all winter till yesterday? I only ran it for about a minute when this happened as I thought it was out running out of gas. I need to figure out how to access the impulse line? Where is it? Under the carb or....?

Connects from the carb to the crankcase. Pulses the carb diaphragm to pump gas.

The impulse line connects to a barb on the transfer next to the intake port; it is also integral to the intake boot.
Make sure your saw has the little metal insert in the intake assembly.

If I remember right pre 2008-09 5100's didn't have them creating a potential for an air leak.

It might be possible the little green pulse line just came off, easy fix if it did.
