Hi Chaps I am new to the forum and have a interesting understanding of this fault. Would people be interested in a gear driven conversion as I have a finished design and would happily let someone test it on their engine. I am strongly against the mods that have been suggested and put forward by the engine builders as they leave the belt open to the elements and on a m3w the slots are right at he front so not good. I have been involved with this engine until recently and I am happy to support where i can whether is be 3d models or additional information.
