Ms200ts carbs/piston kits

[Acg128]

Taken two of my old ms200s into a lad I found that does repairs and he's saying one need piston and both may need carbs.. Non genuine carb £85 genuine £120 quick scroll on eBay seems a bit steep to me? Piston kit £11.99 any help appreciated cheers

Whats wrong with the carbs? and i would be wary of putting in a 12 quid piston kit.

The best non OEM piston will be the Meteor one, I have fitted many and with no issues. The real cheap ones are.....well.....really cheap so is it worth risking bad circlips or brittle rings??? Meteor ones are circa £25-30, a bad piston could take the top end out and result in a real expensive repair and more importantly, downtime!!

 

The carbs - I have only ever had to replace one carb. Faults can often be fixed by the more experienced tech but some will fit new just as it is easier and quicker for them to do so. I can spend an hour on one to resolve a running issue as I just give a fixed price repair - my time my choice!

 

The main thing to do is to verify the parts do need changing and the cost of them makes for a viable repair! Some may just fit them as "it may be the issue" rather than KNOWING it is the issue!

He says that a screw in the carbs that hold some rod to stop them flooding or something have been glued which keeps causing it to clog.. He's going to do that special cleaning thing to the carbs so fingers crossed. And apparently the piston is scored, it's the meteor ones I was looking at.

Your description sounds a little vague, it could be that the needle valve has been glued in - now that is a strange one, never heard of that before!!

 

A deep ultrasonic clean may well do it, depends on the power of the cleaner and if it is heated.

[Acg128]

Yeah ultrasonic cleaning.. The needle is fine but a small screw located in the car somewhere near that has been glued prior to me getting it.

£600 90c heat cleaner there going in at a main dealers, has superglue in apparently guessing a gasket went or something on the previous owner.

have you tried nick wicker at horam ?

You can use a quality pair of side cutters on the screw thread if the cross head has failed - there is no guarantee the head won't come off though!

 

The cutters should be vertical to the carb and the cutter ends embedded in to the head on either side if that makes sense!
