ms230 starts then stalls?

[shillo]

cleaned carb and filter in carb

replaced seals in carb

new spark plug

new air filter

new inlet manifold

new impulse line

new fuel line and filter

still cuts out with breather pipe removed

 

Saw starts, revs up a bit then revs drop and stalls.

 

Im about ready to throw it in the bin!

So have you wound the idle right in to see what happens?

 

"Seals" in the carb......what seals??

 

The MS230 has an accelerator pump as it has a C1Q carb and it sounds like the pump has failed or a welch plug is leaking!

 

Looks like you have spent a lot of money chasing the wrong fault:thumbdown: Should have done a pressure and vac test first!

[shillo]

Thanks for the reply spud.

 

I got a gasket set for the 230 and replaced them all. thinking that might solve the problem.

 

I haven't tried screwing the L screw right in yet.

 

I don't have any pressure testing equipment,

 

stupidly thought it was going to be an easy fix!

 

Sounds like a new carb then? especially as I've never heard of a 'welch plug'?!

Not the L screw, what I meant is what happens if the idle LA screw is set to a fast idle, does it still die?

I've been working on one of these saws tonight horrible little thing to work on, prefer working on the pro saws...

Exactly!

I don't mind working on them. Can have them fully stripped and back together in an hour or so.

 

They are a bit notorious for bad carbs and crank seals tho. Certainly sounds carb related tho if you've replaced the fuel line.

Its not a rarer one with the fuel primer bulb fitted is it?

The one I was working on has no primer bulb

 

It's a 2006 has the wrong bar nuts on it and chain hanging off it...I said to the guy and he said "aye ano I just put a screw driver in there and leaver it tight"

 

Hahaha I said why not just turn that little screw there!!

I had similar problem with my ms180 ages ago turns out it was the exhaust/muffler gasket.worth a try!

Most don't have the primer bulbs, but they where on both ms and pre ms "0"models but ive only worked on 3-4 having primer bulbs out of probably 40-50 ive worked on.

Chain tensioning... lol my pet hate is the quick adjuster jobs and just 1 bar nut. Although the stupid easy easy starters where you pull it and about 2 seconds later it actually spins the engine weirds me out every time.
