Thermostatic valve hot air intake

[mrFloppy]

I am in the process of sorting out my mum's old ae92 seca for roadworthy and put it up for sale, personally I would sell it as is but mum is attached to it and wants it  to go to a new home so I have to fix a few annoying problems first. One thing that is hard to find is a Thermostatic valve hot air intake Part #1772816010. It's the little plastic vacuum valve that sits in the air cleaner housing and operates the flap that allows hot air into intake or not when it is warm. Not really critical but nice if it works, right now it always leaves it sucking hot air, always. Genuine says it is a discontinued part but I was hoping there is a aftermarket replacement available that someone might know about. Tempted to unhook it but thought I would see if one could be found. Second problem is it runs beautifully when cold but as the gauge gets to operating temp something is switching on or off(not choke) and all of a sudden it has a rough flat spot which struggles to get the revs up. It is a carbied 4a auto that has been well looked after and could be a sensor somewhere. I haven't had this problem before and was thinking it could be a common thing that you guys might be able to point me in the right direction. A new set of leads is also planned just in case. First time I have had to work on a 4a so any common problems they have are new to me.

Appreciate any help,

Cheers

In regards to the valve, Amayama may be able to get a hold of one, but it is a long shot.

Another option is a wreckers.

Thanks for the amayama tip, they have them but $70us is a bit much I think. It might have to be the wreckers but propably a good chance they will be in the same shape. I will spend some time on google hoping to get lucky.
