Gday,
First, I'm only a fledgling mechanic so please don't reply without expanding your acronyms for the newbie!

I have a '92 TR 2.6L Carby Magna Swagon:
question is, are the carbys on manuals absolutely identical to those on autos?

I have a '92 TR 2.6L Carby Magna Swagon. It runs rough and when you put you foot to the floor you don't get the usual power response, in fact if you are on a steep hill you can get some shudders then lose power and have to gear down to get revs back. Fuel pump is fine, leads are new, dizzie rotor looks ok. My timing chain will need doing as it has a bit of a rattle. The head gasket has a leak I can tell because the hose feeding water from the radiator to the engine is flexing when you rev. I know these two last problems are fairly serious but I'm guessing they aren't actually responsible for the lack of engine response on full throttle or the losing power on steep hills with foot to the floor..

I'm suspicious of the little UFO shaped vacuum container under the carby to the left. I want to grab one from the wreckers (probably have to buy whole carby) question is, are the carbys on manuals identical to those on autos? I'm told the vacuum setup could be different? It's hard to find a manual 2.6L carby TR so I need to know if I'm safe ripping one of an auto..

Also, was wondering, workshop manuals are the comprehensive reference for your car and service manuals are sort of half as much info is that right??

Thanks in advance for your help car doctors/wizards!!

Please advise!

From what I've seen the carbies all look to be the same. You should even be able to use a carby off a Sigma or Scorpion without any trouble. Is the vacuum valve thing you talking about the one for the air conditioner? It sounds like it might be running a bit rich, maybe it needs a tune or a clean out with carby cleaner.

you will need to change bass plate .as auto carby has the auto kick down on the bass plate.

Thanks for responses guys.

I have used carby cleaner, the carby was too wet I think as well..

Base plate sounds like a hassle I'll have to keep searching for the manual version of the TR carby.

I'm wondering if a reco'd one for a TP magna 5spd manual would fit my '92 TR 5spd manual?

Thanks guys, whoever is hosting that workshop manual is an absolute champion of the first order. I found it a few weeks ago and grabbed a copy, so so so helpful, thanks for pointing me at it Perry.

I pulled the carby out today and discovered that the depression chamber is faulty and is the likely throttle problem so I'll replace and see what happens.

Thanks for pointing out the base plate difference.
