You have to call them. They had 4 of them last time I spoke with them. We bought one a few months back for around 300-ish. These are universal 32/34 DMTL's with means they WONT be jetted properly for a 2.25 rover. You have to give them he correct jet #'s. I have these written down somewhere but cant find it at the moment. Might have been in the defender 90 Haynes manual??

Terry is right, worst carb ever. I tried rebuilding it twice. What a fiddly carb to take apart and put back together. I absolutely hate this carb as far as rebuilds go. But when its setup properly, it is a nice running carb.

They sell on ebay.uk too. But one guy wanted $130 for shipping

EDIT: I took out each jet one by one from front to back and cleaned them. Also wrote down the number on each:

Front to back:
Jet 1 = 52
Jet 2 = F-30
Jet 3 = F-39
Jet 4 = 6U

Anyone know if these are in the correct order?

F30 and F39 are emulsion tubes. The main jet and air correction jet are attached to the emulsion tubes (top and bottom). You also have a accelerator pump jet and ventri tubes to check. But those require full disassembly to get to. I suggest waiting for a manual before you attempt this.

EDIT Found manual here complete with jet #'s: http://smg.photobucket.com/albums/v3...rb%20pictures/

Any idea in which order they should go from front to back?

I don't believe I am capable of disassembling/reassembling a carb (as of yet). I've taught myself to do a number of mechanical fixes by reading the net and asking questions. The rover has beena great learning process. But I feel I've exhausted my skills for resolving the sputtering and rich running rover.

So far I have replaced the cap, rotor, plugs, plug wires, cleaned carb jets, adjusted valves on a warm engine twice, replaced all intake/exhaust gaskets as well as any leaks in the exhaust system, fixed any vaccum leaks, and adjusted timing forward and back with no positive results.

I can only guess the problem lies with the carb or the distributor.

The folks at Pierce are very helpful and rover knowledgeable (as you might expect). The would probably rebuild your carb if you sent it to them.

I'm no sort of mechanic, but my 32/34 has been running like a charm for years in all sort of nasty conditions: love it !

YMMV, Andrew

I dont remember. Its one of those things that I'd have to be in front of to remember (wasnt my truck).

Could be. But I'd check compression and better yet, do a leakdown test. You could have a burnt valve.

I definitly have faith in it as it ran good at one point. I emailed them a day or so ago but have not heard back. Hopefully they can rebuild mine.

I would guess the 53 jet and the F30 emulsion tube go in the 32 mm side and the 60 jet and the F39 go in the 34 mm side. You could blow some carb cleaner through the holes where the jets go and determine which hole feeds which venturi. That is assuming you can visually determine which side is 32mm and which is 34mm. I've never seen this carb so I'm just throwing this out there..
