Echo SRM 210 won't start
Hello all, need a little help with my Echo SRM 210. It's about 5 years old and at the end of last season it was getting a little hard to start. I chalked it up to it needing a carb service and just let it be. I got it out this year after it sitting for 2-3 months and found it leaking gas. It had soaked air filter and felt pretty sticky like most of the gas had evaporated and what was left was the 2 cycle oil.
I didn't even try to start it when I found it like that I just decided to start replacing stuff. I thought about a card rebuild but a carb rebuild kit was $11 and a new carb was about $40 so I just got a new carb. I checked the serial number and got a ZAMA RB-K75 carb. I also got a new spark plug and fuel line repower kit that had a new grommet, fuel line, fuel filter, etc. I put those all on today and it's still not starting.
At first I thought maybe I had flooded it by priming the new bulb too much so I let it sit for a few hours and tried it again and it still won't start. When I'm trying to start it I can smell a faint odor of fuel burning so I think it's getting a spark.
I was reading around for solutions and someone mentioned taking the spark plug out and putting in about 1/4 teaspoon of fuel down into the spark plug hole, putting the spark plug back and trying to start it. I guess to make sure it's not a fuel deliver problem. But that didn't do anything for me either.
So what's next? I haven't taken the exhaust apart. I was going to try that next to see if maybe there's just too much carbon buildup. But if there's something else I should be checking please let me know. Thanks in advance.

Well the good news is that I got it started this morning. Before trying to start it I did take off the carb and clean the screen. There wasn't much build up but thought I'd mention it. Now I can start it and it'll idle fine but if I try to give it even half throttle it dies on me. Are there any adjustments on the carb itself that I can make? Or any other ideas?
