OK... Totally confused. Just measured stock carb. 18mm pumper. Couldn't get butterfly out due to screw wanting to strip, Slide was 16mm and intake was oval. 18mm top to bottom and 16mm side to side. Small body. I"m running a "20" right now but haven't measured it yet. Super hard starting and runs lean so I suspect a fake. Also have a small body "23" pumper with a 22mm slide and a round intake but a 23 out with a step. Just got a Naraku intake manifold to fit a 24mm non-pumper with a large body and oval intake. 22mm slide and 22mm wide by 24mm tall intake. Outlet is stepped and measures 24mm. Racing planet offers a 24 Naraku that looks identical including the outlet step. Can anyone enlighten me? Forgot to mention I'm running a 52mm BBK, Big valve head, A9 cam, and stock exhaust. Want to run the 24 and derestricted LeoVince Titan exhaust I just picked up. If you can't pull and measure the butterfly does the slide size tell you anything and is there a difference between the large and small body carbs? Also, any difference between the round and oval intakes? Sorry the post is so long but just trying to get this figured out.

I dont have a tool to measure can anyone tell from the picture if this is the "machining"? or does it look like a 20mm? Purchased from 02starrider That being said a fuel line was damaged and had to be replaced.I also ordered a BBK which was missing the A9 racing cam and the piston had a ding in it so I returned the whole kit.Now I have this carb and from the pictures on here it looks to be fake.Wont purchase from that ebay seller again.Shoulda returned this as well   |

That's actually where I bought my BBK and A9 Cam that I'm running right now. Maybe things have gone downhill a bit.. |
