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 |

I used a baby medicine dispenser for a graduated cylinder, readily available at any drug store. I found that with an increase in pump jet size (I was at 45s, now I am at 55s) and with replacement of the pump spring I was able to get close to the .4-.5cc pump volume as spec'ed in the dell book. The hesitation I was having when mashing the gas is almost completely gone . . .
