String blocking piston on 201

[TTownsend]

Finishing the week with some maintance, was changing over chain oil pipes and obviously put some string in to the cylinder to block it off and when going to take the string out it snapped and half off it remains in the cylinder (don't you love Fridays)

 

Is there any quick fixes ? I've tried hook it out but having no luck. Or shall I just take it in to my local garden machinery dealer ship ?

 

Cheers

Chances are the piston wasn't quite far enough up the bore and the string went in the exhaust port and jammed as the piston came up, whip the exhaust off first and see if you can fish it out. Otherwise the cylinder will have to come off.

Could you not blow it out of the exhaust with an airline in the sparkplug hole, or better get the vacuum cleaner at the exhaust to make sure it travels the right way and not into the crank case

Its probably caught in the side of the piston.

Try getting hold of it with some needle nose pliers through the exhaust port, may have to turn fly wheel back/forth to release it.

Failing that you will have to remove the cylinder, its all good fun.

You really used string, not even starter cord?

[TTownsend]

Okay sweet I'll take the exhaust off a hopefully blow it out with an airline

Make sure that it's all out, had some cord get involved with the ring and ruined the cylinder before. Think it actually caused the ring to break.

Using rope is a good practice when you are careful and know what you are doing. Issues arise when you don't know what you are doing:001_rolleyes:

 

This one just depends where the rope has sheared and if any has been lost. If it has just been sheared in the exhaust port then it is a relatively simple job but if some has gone in to a transfer, the remains may end up floating round the engine and that may cause issues if fibres float around the piston or main bearings.

 

Foreign bodies in engines like this can easily cause slight undulations in the cylinder wall severely knocking compression......just saying!

I knew what I was doing, just not thinking (at the time) about what I was doing:blushing: an expensive lapse of focus in the job in hand.
