When you are trying to start it does the plug get wet or stay dry?  Pull it through hard a 8 or 10 times with the choke on & then check.  Assume it feels like it's still got good compression?

On a difficult start, I always make this evaluation. I think this is very important.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .

It has very good compression . After  10 pulls the plug smelled of gas but I couldn't see a lot of gas on it .  After checking this , I put it back in and it would fire and try to start but would never run .

It obviously is not getting fuel for some reason which goes right back to fuel delivery .You either have a plugged fuel line ,no impulse or a screwed up carb .If that thing has fire and fuel it's got to at least fart a time or two even if it won't putt .
