Are all the linkages spotless, clean springs and lubed?

Nah, I think they are lower in those ones, maybe just airlocked ya reckon. There is a bleed bolt next to the thermostat housing I think???

Hit it with a hammer

Well I worked out 2 of them went to the dizzy so there ain't no water in those suckers. Certainly lubed to heck.

I had an old 85 Hiace van that had a carb with auto choke that was a real pain in the arse, so I pulled it off and ran it over with a 30 ton cat digger.

Replaced it with a manual choked carb off a cressida. Was all good after that, until the wife found a fencepost on the side of the road at 80+kph.

I dont think it has water passages mate, not if it has an electric spring. My money is on the spring losing its heat up properties.

surprisingly hard to find parts, but must pop into local Toyo Commercial wrecker & see what they have again. Just wasn't sure what I needed.

So why isn't my idle up working when I turn the steering?

Depends how it is operated, my guess would be vacum pressure?? You will have to find the diaphram that operates it if that is the case and make sure it is working correctly.

As a quick follow up I went to see a mate, ex mech with same van & he helped me adjust the idle up on pwr steering and the fast idle on the carb, which was also sticking. There's like a bob weight that pulls flap etc open after electric bit turns off. Crazy stuff, but he figured it would need another tweak to get it perfect. So far it's a big improvement, but i need to turn the choke back on a bit when it's real cold so I'll have another play.

bit step was taking the pass seat right out so we could get to see everything.

Glad to hear you're getting it sorted mate

**unstuck** · 19th July 2013, 18:04

Good to hear. the old manual choke had alot going for it really, too simple I suppose like a lot of stuff these days.

Yeah had it on my old C20, but maybe Toymotor wanted to be more civilised. This car stuff is still alien to me.

God help me if my electric curtains start playing up...

Did you check the kerfuffler valve and does it have a red or green powerband?
