First off---DON"T WORRY if your engine started backwards! This happens every now and then and does not indicate anything negative (unless of course your leads are reversed on the box). It is simply a matter of releasing downward pressure on the car at just the right time, resulting in the engine kicking back ane starting in wrong direction. No big deal. I have seen this happen several times over the last 15 years or so, and by itself does not indicate anything wrong.
I am not sure how your brake cam opperates, but check with your engine and radio off. Apply throttle manually....do your brakes come on? If wo, remove the fuel line from that side of the linkage.
If you have identified your engine accurately, it takes a turbo plug & requires NO copper gasket.
Putting a fuel filter in the pressure side causes no problem as long as it is not leaking. To be on the safe side, remove it, at least until your issues are resolved. Some run a pressure chamber in the line. This dampens out the pulses like a longer line but keeps pressure up like a short line.
The term 'bog' is generally reserved for an overly lean condition, as it is descriptive of an engines reaction when starved for fuel. Unfortunately, many people use the term whenever the car fails to react instantly to throttle input. This makes it very difficult to get helpful advice over the phone or internet.
After checking out the brakes, start the engine and leave it on the starter box. Begin revving the engine (in bursts) while slowly richening the main needle. You should be able to get to the point where you can hold wide open throttle with the engine making relatively low rpm (producing LOTS of smoke and some raw fuel coming out the exhaust). Start leaning the needle, while holding WOT. As soon as engine begins to clear and make good RPM, release throttle and begin blipping the throttle while leaning the neadle. Stop leaning the neadle when the engine begins to react more closely to your throttle inputs. At this point, it should still be generating a fair amount of smoke, and should still be on the rich side when you put it down on the ground. You are ready for fine tuning the main needle.. Make high speed runs, lean 1/8 of a turn at a time, until it clears out and makes good power. Check temps. Should make good power at around 230 F. Try to keep under 250F.
