i must have a different engine than yourself because mine does not have a mixture screw.
the new carb on order has a high and low mixture screw, but it still has not arrived......
Oh yeah, it does....idk...it fixes everything from off idle stumble to WOT fuel starvation, idk it even makes it run better on super unleaded idk and keeps the backpressure in the muffler for top speed!
yes i think your right it is a delorto replica. i ordered it a while ago but the snail has not turned up with it yet.

i was going to fit fuel injection off a v12 jaguar but it did not have any mixture screws to play with so i opted for carb upgrade instead. lololol.
i bought this off ebay it produces aprox 5500/6000 bhp with after burner if i bolt it to my engine i can use it as a carb but i will have to fit a massive mixture screw somewere.
