why echo 2 stroke is hard to start?

my Echo srm-210 sometimes just takes a few pulls to get her started. Runs fine once started. Other times it might take 10, 15, 20, 25 pulls to get her started. Sometimes i give up, then the next day she might start up after just a few pulls. Spark plug is fine. Replaced the fuel mixture. Air filter is fine.

I push the prime button as instructed in manual: "4-5 times after fuel is visible"

It never has started with the choke on. I learned long ago to cold start her with the choke off. Still, when she wont start some times I go ahead and on the choke, but that never helps.

What could be wrong?

tks,
pa

It sounds like the needle valve in the carb is not sealing well and the carburetor is flooding the engine while it sits.

Are you giving it full throttle while trying to start it? If not, try that, it might make it start more readily if flooded.

It's probably time for a carb rebuild or replacement then.
