longest part was tearing it all down n buying parts if u needed any rubber parts inside n putting it back together.
I mite of soaked the parts 30 minutes or so. Then with a small brush get any tarnish yellowish brown crap off.
Some areas u can't get to, like inside jet ports, but do ur best to just blow those places out....carefully.
Make a small soda blaster. They clean the inside and outside extremely well. And it's pretty cheap. Like 5 bucks. Plus a few for soda. You will spend that in carb cleaner and this is better in my opinion.
