Im looking to swop all the parts from my existing 30 Dellorto into this one but my existing one doesnt have the slots and holes in it. Do you think i will have to re jet ?

Personally I’ve never seen a Dellorto phbh with those slots at the back which makes me wonder if it’s actually a 2-stroke variant and could be a 4-stroke variant converted. My advice would be not to bother as carbs are a fickle thing. :|
