My first brick, an '86 245 had the flame trap in the older position, below the intake manifold. I didn't even know it existed, let alne where.
When I finally found a shop where they knew why my oil was leaking at the filter gasket, the guy reached in with one hand and pulled the flame trap unit out. Took a minute or probably less.
I never could do it that fast - but I know it can be gotten out.
I'd suggest removing the dizzy cap as B.C. suggested, and also...
I'd suggest you take a look in the FAQ re. the how to remove the breather box without removing the intake manifold. There's a method there where you remove the idle air control. May as well pull off the throttle body at the same time and clean both of those.
With the i.a.c. and t.b. out of the way I was able to remove the late model breather box. I'm sure you can get the flame trap out and re-pipe it with those two goodies out.
Cleaning the tube down into the crankcase:
It's fragile and a real PITA to replace if you break it.
I used GUNK motor flush to clean the tube. Just trickle some in via a small funnel. Leave the funnel in after the fluid goes down, and send down a single split of household cheapo extension cord. If it hits hard stuff, add more motor flush. With that done, remove funnel and ream with a stiff poly rope. Should come up with motor oil on it.
Do an oil change after to get that motor flush stuff out of there.
While you're in the neighborhood, pull the flexible air duct to the throttle body and check for cracking, especially underneath.
