If you've bought parts for the project, use them.
I'd purchased the Arnnworx throttle reseal kit after I'd assembled the engine (procured from HondaDustr, aka Greg, as you may recall). But since I had the intake manifold off and to give myself a break from that godforsaken heater valve, I pulled the throttle and had at it. I've always kind of liked overhauling carburetors so this was more comfortable leisure time.
A couple of observations:
1. What nicely made things these throttles are. Needle bearings and a throttle plate that's easily removed. Built to be serviceable. Today's cars with electronic throttles generally go in the trashcan and require a $1500 replacement.
2. The Arnnworx kit is a solid deal at ca. $20-25. Yes, if you were a shop doing these all the time, you could figure out the size of the o-rings and re-use the old screws, but even this tightwad thought it a good value.
Not the world's most interesting pictures:
I used various picks, some NAPA carb cleaner, Q-tips and compressed air.
A pleasant couple of hours spent on this. From the reconditioned fuel tank, through all new hoses and lines, a new pump, serviced injectors, extra filtration, this car's fuel system has been comprehensively serviced.
ciao,
