Hey there, so I got a non runner 1986 350d off someone I know, and it’s been hell ever since. I brought it home, fresh gas, fresh battery, and it ran. It bogged down at full throttle though, so I went and bought a fuel pump and air filter. Then I did an oil change and took it for a quick ride about a mile and back down a gravel rode. Came back and was about 200m from the house when I downshifted and it died. It started to throw smoke (I think exhaust, might not be though) through the hole on the engine block on the right side, and it would make a weird noise when I tried to crank it. It’s hard to describe other then not normal.

Today I cranked it, and it runs. Just not good at all. It bogs hard and is not sounding right. I took off the air filter to get to the carb and I noticed there was a line, which I think is a vacuum line maybe, that branched off the carb that was split in half. So I went and bought a splice and hooked it together, and it didn’t help. I am clueless what to do, any opinions?
