SU HS2 Carburetor Assembly | Triumph Spitfire Restoration - Part 102 

I use one and a half gallons of that carb cleaner in a cheap stainless steel cook pot for my Weber 40DCOEs, I keep some big river rock pebbles, to surround the carbs and raise the level of the cleaning fluid, (thanks Archimedes), above the carbs, I strip all the internal parts out of the carbs and clean them in the basket. I leave the carbs soaking for three days, then once cleaned out, I flush them out with distilled water before drying them on the bench with a hot air gun. Webers have fine passageways, which do NOT like ethanol laced fuel sitting in them. My first and last fuel tanks of the season are always ethanol free fuel. The carb cleaner that's left, I keep in the shed to reuse next year! One day I'll get myself an ultrasonic cleaner!

Thanks for the shout out buddy! Carbs look great! FYI be careful of what’s in the ultrasonic cleaner before you put your intake in there. Some products with eat/etch the aluminum and turn it black.

That came out real nice! I've been tossing the idea around about finding an EFI solution for my spitty.. Time (and budget) will tell.

I've got a set of HS4s for my 1500. I'll be doing this myself if I get the chance.

My turn to say...i get the first comment! 😂

Most if not all of the carb cleaners are shit, they ain't what they used to be, pros have stuff that can make'm beautiful, don't know if any of them would just do the cleaning & plating for you with out doing the assembly. Does the piston fall with a solid metallic 'thunk'??? Is it the least bit different if you do it with the choke on/jet down? If not, it ain't centered, do it again! Float level? Find out & set the tab, also IIRC the float drop is adjustable too but isn't as important. Throttle shaft seems a little stiff, oil/grease would be nice, then again it attracts smegma and you're a long way from wearing out the shaft & body. Good luck.
