Agreed....The one on the left is definately Predicta/4. The other style is A/M. A mate owned a mower shop 25 years ago and Im still sure he has boxes of them,he bought them of an A/M supplier around this time. They come up on Ebay from time to time but no one bids as they arent original. The late Roto 2,2a and Predicta shared the same fuel tap( The one on the left). There are no other Genuine tap styles for these models that im aware of,only the one on the left...:) BUT if someone would be kind enough to verify or correct me that the one on the right as being
Rotomo or 2a,Im going to get the whole lot off my mate!!!! lols.
