anyone here know small engine repair

One comment tells me all I think we need to know-

it runs smooth as a kitten when I restrict the airflow to the carb choking it almost closed

This means that the fuel passage is partially blocked and you are not getting a free flow of fuel to the intake. On regular carbs, this usually means the idle jet is clogged and by blocking airflow, you are enrichening the mixture. Usually won't happen on a "dip tube" type, but seems certain that this is your problem. By the way, the "dip tube" works on the very simple Bernoulli's Principle, the faster speed of the air along the top of the tube leads to reduced air pressure there and hence produces a lift of the fuel below it. When you choke the carb, you cause the air coming in to enter at a faster rate.

Your problem is most likely as mentioned above- crap in the gas or the nozzle entering the intake.

Very Well said Boss !

The engine has never stopped running so there was no getting it running again and it has been running the way it is running now for prob 3 seasons no change but I simply have not bothered to look into it because I use it for 10 minutes every 2 weeks or so and then put it away with other projects on the plate.
Yes when I said this......... it runs smooth as a kitten when I restrict the airflow to the carb choking it almost closed so I guess that again its not getting enough fuel for some reason........ my next thoughts were .........so I guess that again its not getting enough fuel for some reason.
Hopefully this does not sound sarcastic
Quote........Usually won't happen on a "dip tube" type..........
I am/was hoping that someone can tell me exactly why, I was hoping that maybe someone here has had the same problem with the same sort of carb.
Bottom of the tank is shined like a mirror almost and yes I don't have any thoughts of fuel additives fixing the problem but I have some laying about so I will try this before I pull the carb off to blow out and clean.
BTW you may already realize this Rusty but making gaskets is easy using an old cereal box, I hope it does not come to that because I am thinking that partial exhaust removal might be necessary and those nuts might not budge easily.
Thanks for the explanation on the dip-tube, now that it is explained to me I am quite sure that I remember some autos a bit older ( mid twenties and before ) than what I am used to messing with using this type of system, only read about it though and have seen schematics but have never had one apart.
Thanks again to everyone that has made suggestions, I will work it out and hopefully report back what I am able to find, if not than I will have one gently used working like brand new edger for sale on e-bay : )

That type of carburetor has a built-in fuel pump, in order to pull the gas out of the gas tank. It does not have a fuel float bowl, lots of check valves and springs. Try running some carb cleaner through it.
I have taken the bolt that holds the air cleaner on out and while the engine running putting the palm of my hand over the air inlet and choke the engine till it almost dies, a few time to  pull any dirt out of the carb

Thanks for the tip, I am in the process of running cleaner thru it, I poured some in yesterday ( alot ) and after finally getting it to re-start it did seem to run better. I let it sit and did the same, trying to get the cleaner thru the carb and then let it sit to do its thing.
I will see today what progress I have made.

PB BLASTER has a product called lawn mower tune up in a can.  I usually get it at Lowes for less than five dollars.  Buy some, follow the instructions on the label, spray some into the carb throat while running every now and again, be happy with the results! 
I've been working on small engines over 40 years and this stuff is a great time and effort saver.  I've used it to start 2-cycle engines needing carb rebuilds until I take the time to fix them.  It's difficult to dose automotive cleaning products properly for small engines- this takes the guesswork out of it.  Also,  make sure that the air filter is clean.   This almost always helps neglected lawn equipment.  I clean all of mine several times a year.  Good luck, Gene
