That has less of a bearing on the injected engines, where petrol is injected near the valve and atomized by the injector.
But back on track, I wonder why the OP has not followed up on his post.  |
Yes, wonder how he got on.
With regards to injection, it only works for multi-point injection.
Single point is still very much a 'smart' carb
Oh, and molecules don't get bigger............or increase their surface area.
Molecule size and surface areas is pretty well defined by science
It's the better mix that helps
