Ok some good news....I did put gas in the cylinder and it fired right up. It quit shortly after. It seems as though it definetly is not getting gas though. At least I was able to rule out a few things. I am going to investigate a little more when I have some free time.

Thanks for the information.

Like Flatheadyyoungin said, check the above with the symptoms you described.

I would just get the carb rebuild kit. If it runs lean because of insufficient gas, you are likely to seize it, which would be more costly to repair.

I have one of those about 10 years of medium use. Once you get it running here is what I do every fall and have never had a problem getting running the next time I use it. Pour the gas out of the tank back into a fuel can.
Start the saw and let it run it self out. I think this clears the carburator.
I do this with all of my 2 cycle engines and they all seem to like it.
Thats all I do except put some gas saver in the fuel can.

Well.....I started taking everything apart tonight fuel lines, carb, etc. I took the carburetor completely out. It was actually very easy. I checked the fuel line coming from the tank, I tipped the saw upside down and no gas would come out of this line. I think blew on the hose and could tell there was a blockage. I then tipped the saw upside down again and gas was flowing easily. The lines are in good shape with no signs of damage. I cleaned the carburetor off (saw dust) and noticed it has a top and bottom. I took the 4 small screws off and there was a rubber gasket and I did not want to pry it off but, it would not come off. I did not want to force it for fear or ruining this gasket. Should I try a little harder? I did take the other side of the carb off ( 1 large screw) and there is really nothing there that could be blocked. I cleaned it up with carb cleaner and there were no issues. I put everything back together and didn't try it too much because it is 9pm at night around here in a small subdivision and I didn't want to wake any neighbors. I think I will try it again tomorrow where I won't be afraid of waking anyone.

Should I try and get the one side of the carb off? Also the fuel line going from the carb towards the engine is there a way to get this clean?

I will keep trying it out but, I expected that the fuel line that had no fuel flowing would do the trick. I will try it again in the next few days.

Thanks again!

Don't want to tick off the neighbors.....You mentioned that one time you got fuel flow and the tipped it and couldn't get the fuel to flow. It is a bit of a pain but not impossible to replace the fuel line from the filter in the tank to the carb. I maybe collapsing and kinking on you. That single screw that you took off on the carb is usually the diaphragm side. It doesn't take much gunk at all to block that up. I took that part of my carb off the other day because it was running poorly. Two tiny grains of sawdust were in there about the size of big grains of sand. That's all it takes sometimes. Just be careful with tearing that diaphragm. I would leave the side of the carb with the four screws until you have tried it out again. A carb rebuild kit is about $12 for those things. When you put the carb back on make sure that the boot is clean and pliable so that there is no air leaks. Don't tighten the carb mounting screws too tight also.

Good afternoon all,

I thank you all for the help. I did just get the saw running. It turns out it was a blocked fuel line from the tank to the carb. I put everything back together and after about 10 to 15 pulls it started up. It since is starting up right at the first pull.

Thanks again for all the help.

blocked fuel line

Reminds me of the time my son, bless his soul, poured a box of gelatin into the fuel tank on my Homolite saw!

Yes it did happen!
