Re: Weber carb install.
At 2.5 psi fuel pressure , you do have to do some testing to get it dialed in as far as height . Some seem to work great , others need the float down to about 1.45" . I'd say the biggest difference is in the pump , a good bellows type is more consistent and steady in it's flow rate than the pulse type electrics . The biggest help is the tube and running a good consistent regulator , along with dialing down the pressure to 1.5 or so psi offroad . Most Sami engines can't draw enough fuel at wot to empty the bowl fast enough to outrun these float settings , on a larger 2 litre or so engine it could be a problem due to volume . Also, just as a heads up , if you really want an improvement over the usual 32/36DGV's go find a 38mm Outlaw . Those are designed for pure performance , no intentions of fuel mileage at all . Torque off-idle is increased quite a bit since they are synchronous and not a progressive primary/secondary . Gas mileage definitely sucks , but the power is worth it if you have a decently modified head to go with it . I'm working on stuffing a 40DCNF onto a Sami 1.3 intake now , just got to finish up the plates and the linkage ......
