I understand that a few people have made good engines out of these kits but only after a lot of extra work .
Neville was more than a bit upset by problems people had with the 5 " version of the Winson 1400 . Everyone assumed ( and its possible that some people were led to believe) that the Winson one was a kit version of his design .
Numerous problems were referred to him which he tried to resolve but when in the end he was actually able to examine an engine in detail he decided to have no more to do with them .
There are issues but these can be resolved if you have a workshop – this phrase appears ( with variations ) in most adverts for part built kits . Draw your own conclusions .
