Hi guys, have a bit of an issue here, didn't realize till it was too late that the new motor we bought has a different intake/carb on it. The new motor has a few less vacuum lines, and I don't know what I should do as far as T off from other ports to get things working properly. My main concern is the missing line going to the front of the truck, I have no idea what that stuff controls. The missing line going to the rear appears to just go to the Charcoal canister... so maybe no big deal there. Just in case anyone else does a motor swap in an Acty, just drop the motor and trans out... will make your life way easier.

here is a diagram https://minitrucktalk.com/threads/honda-acty-vacuum-diagram-1995.14400/ some pics here https://minitrucktalk.com/threads/installing-new-carb.16144/ https://robrobinette.com/Honda_ACTY.htm
I have a manual for the truck, but he diagrams are incorrect for my truck and for the new motor, so neither are of help. I can find diagrams all day long, but I don't understand what I need to do with these lines since they are not the same as what the truck came with. I'm sure there is a way to make it work, but for instance, I have no idea where the slide needs to draw vacuum from, since the old carb does not have a line going to the slide or rather above the diaphragm attached to the slide.
Maybe you check in the parts diagrams and find something? That link is now based on my chassis number, 1997 Acty Truck HA-3 with the E07A engine https://partsouq.com/en/search/all?q=HA3-2330294
Well I didn't fix it, but the truck appears to run fine with several lines not connected or rather plugged that come from the control box forward of the engine, and the evap canister line not connected at the back.
