2511 cold start issue

[stewmo]

Hi,

 

My 2511 will not fire on the choke setting (well maybe 1 in 10 attempts) and so I am left with pumping the saw on full throttle until it runs. Then its generally absolutely fine for the rest of the day. Though still won't start with the choke after a break.....

 

Any suggestions? Cheers!

It’s running too lean sir, check out some of the post on here regarding issues like this and all the reasons and fixes to cure it.

They usually run badly when the uninitiated adjust the carb not knowing what they are doing. Just set it back to factory and adjust from that point.

I take it the air filter is nice and clean

Thanks Spud, yeah the air filter is probably a month old and I know to clean it regularly. These saws are very sensitive. But I haven't fiddled with the carb because I don't trust myself to get it right. I can tweak a 200 carb but these ones I have no mastery over what so ever!

That's what I thought until I had to gave a go recently; treated it like any other saw and hey presto - got it spot on!

Here’s the factory settings if you have the necessary ‘D’ headed tuning screwdriver.

Cheers Mark that’s great

And the last post is why most fail as it is no where near 1&1 turns that is generally normal and in my opinion, the average guy doesn't have much of a clue as to how to adjust a carb correctly.

What oil are you running it on. Are you using the primer before cold starting it?

 

Don't go fiddling with the carb settings, if it's running fine the rest of the time it's unlikely to be the issue and you can bugger up a perfectly good saw if you don't know what you're playing with. 

 

Mine runs faultless on hp Rd or hp super, but runs like a bag of shit on hp ultra.

 

Worth checking/changing the spark plug for good measure. That should give a good indication of the carb settings too.
