200T mystery...

[Saw24]

I've searched for answer on here via tapatalk but nothing's coming up so I'll ask the question that I'm sure has been asked before!

2006 MS200T when cold won't run unless on 1/2 choke, then runs nicely at about 1/2-3/4 revs. But touch the throttle to cancel 1/2 choke and dies instantly, like it's been suffocated.

When warm (left running on 1/2 choke for a minute) I can blip the throttle to tick over, it will sit ticking over all day. Give it full throttle and it does it's suffocation death again. If I gently tease the revs up slowly I can get it to full revs, finger off back to tick over to problem. But gun it and it just dies?

It's got new fuel and plug in it, and a clean air filter.

Is this a common issue? Easy/cheap/hard/expensive fix?

TIA

Carb or carb linkage problem . Piston pump in the carb is a common failure . Not sure if its that though ...

Carb issues. Could be the accelerator pump playing around. If you have a known good carb or another saw swap the carbs over. If it continues it's something else.

I don't have another carb I can swap it with unfortunately, the carb was serviced with a carb kit about 2 years ago, it has had very little use since?

Then I would take it apart and clean it out. Check meter arm height.

 

And ensure the gauze filter inside is clean. Also check the Impulse line is attached and not broken or split.

Hadn't thought about the impulse line!

Meter arm height? What's that all about then?

Sounds like you need a new carb. I've got a 2005 200t and it sat for a couple of years with occasional use.

 

Wouldn't rev so had a new carb put on and not had a problem since.

 

Good luck mate

Oh dear, any ideas how much a new carb will set me back?

I would lay money on it being the accelerator pump, most people don't change them

when they change the carb kit. Its tricky if you don't know what your doing.

Its something you need to be shown how to do, you can do damage to the carb if

too heavy handed getting the pump out.

 

Good luck with it

Oh right cheers. Do you know of any video tutorials on YouTube or such like?
