Mikuni carburetor

FSM88 Thank you for that sage advice ~ a local mechanic/friend Vernon, did remove the box & sector shaft but did not use the entire contents of the rebuild kit software parts ~ he seemed to be aware of the dust cap & oil seal ~ he even hand sanded the sector shaft... The steering improved a lot (it was getting very sloppy) but that darn dripping leak is still there... I just got email from Gary at MitsubishiPartsCentral the only OEM part they have is the seal kit $49 shipped (?) ~ all other 4X4 power steering gear box parts are discontinued and none are to be found on the shelf... I really hoped to get a new OEM sector shaft about $120.00 (?) IF we get the carb problem solved & the truck runs then I was thinking (with your advice) get the J/Y box from Tacoma, WA PicknPull and send it to Hawaii... Use the Mitsubishi factory seal kit and DIY rebuild while keeping the truck able to drive 'n on the road until the rebuild is complete and give Vernon another $200 to swap out the steering boxes... Or, Sam has the Windward Muffler Shop across the street with an outdoor vice & lift ~ I should ask him if he has the knowhow to rebuild a steering gear box..? I like that idea ~ he replaced the muffler with the help of sealant over the welds ~ :^))

Looks like Vernon replaced the cross shaft seals like I did. The left over kit pieces are probably for the rest of the gear box which he didn't touch. If yours still leaks, the cross shaft and housing may be too worn. Hard to say that a J/Y box might have the same issue, but that might be the only option to try if there are no remans available.

Thank you FMS88 for that positive guidance...

Since I been struggling with carburetor issues & an epoxy fix this Google thing popped up & I am saying WTF is this..? Might this be a good thing..?



Toyota was fighting carburetor vapor lock back in the day ~ in hot conditions my truck will drive weird momentarily ~ as though the engine is dead when giving it gas from a stop when the light turns green & sometimes when rolling 'n foot off throttle then giving it gas... In those hot driving conditions, expect touching your foot to the pedal to cause the (vapor ? locked) engine to catch RPM/Power & give the driveline a hard "CLANK" banging sound, not good... So, I wonder if engineering a carburetor cooling fan is worth the time, trouble & expense, think I'm too lazy & having to spend $$ much on other fixes... No garage but time I have from Staying@Home, Thank You Covid :^))

I think the link below is where I read that vapor lock happens worse now-a-days because alcohol (ethanol) has a lower boiling point than gas... It also said why engines run weird from vapor lock (coz the air/fuel ratio is diluted by vapors instead of the liquid atomized fuel getting into the engine)...

This website was good reading for me ~ it has a lot of info about many issues ~ kinda laymen's down to Earth language:

A vanaxial fan that seems to be popular for this very problem:
