New to mightyram50, not to Mitsubishi...

Well, I was able to order the 34 DATA rebuild kit from a supplier in the eastern states. It did set me back the better part of $80 AUD delivered but it is a comprehensive kit with all of the diaphragms and gaskets etc (most only have body gaskets and O-ring seals, so this was worth sitting on the fence for) So I got serious and started breaking this weirdo carb down and clean every component properly - there was gunk packed into every crevice on it in places I couldn't see. The auto choke was sluggish from the get go and I thought that was simply a quirk of this Weber but after stripping it I discovered the shafts were clogged with fouled up grease that looked like tar. A blast or 2 with the oven cleaner, a scrub with an old toothbrush and cotton buds (you guys called them Q-sticks or something like that...) and I discovered this grey stuff called 'die-cast metal' under it. I polished up the shafts on the internal linkages and reassembled them. The tensioner spring in the choke linkages was fiddly to reinstall but once I had it in place, the auto choke was snapping like a mouse trap. A lot easier than adjusting the choke butterfly tension on the Mikuni.

I've test fitted the auto choke release assist, accelerator enrichment pump and the idle up solenoid diaphragm with only one diaphragm left to install - a small one that for the life of me I have no idea what it does, but I have to pull apart the throttle linkages to get to it. As an added bonus the Carbole 42S fuel pump came in the mail this week. Baby steps but steps none the less...
