Hi Guys – I have recently purchased a Mk3 MonroeTiller with a Villiers Mk15 engine and I’m attempting to refurbish it. The first thing I have to do is replace all the cables – not too much of a problem until I looked at the carburetor – Unfortunately it is missing it’s needle. Now trying to find the right carburetor and matching it to a needle is getting a little difficult. The only marking on the carb is V508C – I’m not sure if this is a type number or a casting number – whatever I can find no mention of it in the spare parts listings that I have. Most of the carburetor info I have relates to the Mk10 or Mk12 engines. The only info on the Mk15 states that “on a rotavator where the it is necessary to vary the throttle openings to suit the load, a type S12 carb is fitted”. If that is the case, does anybody know what the needle number is that I require, and more importantly where I can purchase one? It appears that the control cable is soldered directly onto the top-end of the needle – presumably there must be a nipple of some sort acting as an interface between the cable and the needle as I can’t imagine a direct solder joint between cable and needle would be acceptable.

Any help would be appreciated, otherwise I am stuck before I can start!

Regards
