200t troubles

[grantdude]

Had my 200t for about 18months from new. Lately its being playing up and being silly. When i pump the trigger, the revs drop ever so slightly and there is a slight delay before they pick up again , almost like when you are about to run out of fuel. Anybody had the same troubles before?

make sure the filter in the tank is clean, and make sure your mix is good.

Ms200t are renowned for bad carbs ! , when the ones I own startp running as you have described I just replace the carb prob solved!

If I re read your first post... My saws just stall and have no power when you pull the trigger, check the filters and clutch before getting a new carb!

It sounds a bit like it is running weak on the L setting but could be early signs of an airleak through crank seals or rubber boot.

 

I would check the gauze filter in the carb, set it back to factory settings on the L setting and if the problem is still there, turn the L screw 1/4 turn counter clockwise and if it still doesn't work, either pressure check it or check the integrity of the carb boot as a holed one will cause exactly these symptoms.

 

Poor idle can be the first signs of an airleak or just the infamous Zama MS200T carb:thumbdown:

 

Send it over if you want it fixed:thumbup:

Just read your post again - 18 months old - do the L screw 1/4 turn counterclockwise adjustment and tweak the idle up as it will drop and all should be good - I am assuming that your 18 months old saw is still in reasonable condition and not shagged!

Its seen a fair bit of action over the past eighteen months , out 5 days a week definately not for the bin yet. i will give the L screw and idle screw a tweak and see if it improves . thanks for the advice.

Matty, I have one at the moment starts ok then seems very lean when revving up. It then stalls like its run too lean.

 

IYO, is it worth just getting a carb for that rather than messing around?

 

The saw is about 7 years old and has done a reasonable amount of work.

 

Cheers, Pete.

You probably have one of two faults -

 

Dirt in the carb pumping section gauze filter or a split inlet carb boot.

 

Set the L screw to 1 turn out, if it still does it then try up to 1.5 turns but any more and you have one of these faults.

 

Matty - you can run those carbs up to me and I will fix em if you like:thumbup:
