Hello,
Well I think I have just found this issue.
When I bought the Viva I put on new manifold beather hose from rocker cover to airfilter and air inlet in the carb spacer to inlet manifold using Zenith 301z carb. I have got to the stage where I tried everything apart from dancing in clogs.
So my last chance was to replace the inlet manifold gasket. But as I took of the rocker cover manifold breather pipe it come apart, Well it actually fell apart. This was new over a year ago when the issues started. I have pictures but they are too big to add. I replaced with the old one and it seems ok but will give it a proper run when the weather improves. It shows you cant trust new parts. I didn't check it because it was new.
Hope this is the end of the story.
