Yes it is, but look at your pic, that gasket looks soaked as hell so you might do well with a spare.
I think its just a couple linkages, like the choke, pump shot rod, then the round robin of screws.
You could then check your float level and the condition of your needle and seat.
It can be a bit frustrating, so you need to know where you float should be prior to pulling it apart, too low and you run out of fuel when hard on it, too much and your dumping fuel.
Alot of thos 2bbls carbs there if not too far off wont leak much or any while running but just dump the fuel.
You might look on ebay for a cheap kit and float and simply go through it and that would eliminate alot of possible issues and ensure a good carb for a while.
