Hi Norm

I have seen one of the intek ohv's with a snorkel, but I wouldn't call it a modern briggs ohv. All the newer ones I have seen have carby on the left, with a few upper model exceptions

eg https://gympiemowercentre.com/shop/victa-ultimate-keystart-self-propelled-lawnmower/

But some of these are DOV - which have some special lever arm operated OHV - not straight up and down pushrods
