How to adjust timing for a Stihl MS200
« on: October 31, 2015, 04:50:09 pm »
 
I checked the timing key that holds the flywheel in place to see if it's sheared.  It looks good and has not moved. 

After 2-3 pulls the cord will yank out of my hand (IE:  It stops and will not move).

You may have too small diameter pull cord?

Your starter pulley may be split?

Had one that the post where the stater pulley pivots in the starter cover was worn causing the pulley to rub against the cover and the starter pawl to jam. The hole in the pulley was wobbled out also. I bought a whole new starter assembly and all the problems went away.

Remove the starter cover and then take out the pulley and inspect everything?

Does the cord jam up or does the motor stop turning?

The reason I ask is I've had a couple of large saws with a lot of compression hydro lock due to an over rich mixture + the choke when starting. Pretty near wrecked my arm on one of them. I leaned the high side out a bit and the issue went a way.

To verify if it's timing related, try the same start technique with the ignition switch off.

IIRC the MS 200 has roller main bearings? So the following scenario would not happen with roller bearings on the MS200.

If the cage is worn out on one of the crank ball bearings, all the balls will get on one side and lock the crank up. You can jiggle the crank a little and the balls will distribute around the bearing for a short while.

There could be something loose inside the engine and it is catching in the exhaust port? Pull the muffler and look into the exhaust port?

Yes to the bearing, it's a seven roller bearing . A 200 normally would not have enough power if it fired early to literally stop the forward rotation .Might snap your fingers a tad though .

Try it with the switch off .

A thought occured to me .I have a stock 200T they thought was locked up from the Stihl dealer .Set me back all of 20 dollars . ;D  What it was ,was the pin for the brake band came loose and got hung up in the magnets of the flywheel .
