I'm trying to get my Dell 40s set up properly and I'm currently adjusting the pump volume. In the dell tech manual it states that .4-.5ccs should be released for every two throttle pulls for a 1600cc engine. I can only get ~.2ccs for two throttle pulls at max pump stroke. Would changing the pump jet actually change the volume? I don't see how it would. I'm running a 45 for a pump jet, certainly open to suggestions! Also, suggestions regarding how much more pump volume I should be pushing for an 1800cc, pretty mild with 8.2:1 CR and a web 86 over the .4-.5ccs for a 1600?
Thanks, Chris |

Slight HIACK
Isn't a Dell 40 too big for a 1800? i remember reading that a Dell 36 is equivelant toa Weber 40, so reason suggests that a Dell 40 is more like a Weber 44? the reason I ask is that I have a 2 liter of unknown internals that has Dell 36s, but the venturi seems to be around 40 mm wide. END HIJACK BTW, sorry I don't have any clue on the answer to your question. I just got excited seeing a Dell question so I chimed in! |
