My VBB (64 Sportique) has had its engine rebuilt but it won't fire/start.
The bore was in very good condition but I fitted a new, std, piston and rings and had the cylinder honed by an engineering company.
The compression test only showed 50psi/4bar....less than half what I'd hoped for.
There's a good spark and fuel is getting to the carb. I tried spraying "Easy Start" into the carb to eliminate fuel starvation.
I have removed the head and will try polishing it on a flat surface.....any advice on how to do this would be appreciated.
Also, is it best to put some sort of sealant on the head/cylinder faces. I know it shouldn't have a gasket but see some postings saying it's best to use copper spray, copper grease, or the stuff detailed below.
Any advice would be appreciated......Thanks
