I have searched high and low for a Marvel MSA3 carb, parts list. to no avail.
Does anyone know the web address for it,or is there another place to look?

I don't think the parts are available on their own but there's an overhaul kit with everything you'll need. I can't remember where I got my last one but it would have been either Airworld or Multiflight.

Graham,

Answer your PM, I have the info on file.

Caution on the overhaul kit, there are special tools require to remove parts of the venturi. Also, the price of the overhaul kit has rocketed in the last few years. Last time, we just bit the bullet and went for an overhauled unit from Spruce.

You don't need any special tools to remove the venturi. It's held in place with Three little clips and although they're fiddly, removal and replacement can be done with a little care.

I am aware of the kits etc and have the tools I need, but I wanted a copy of the parts diagram to associate the parts to the number, I use a mechanic toolbox, disc but the new one no longer has the details the old one had or the diagram. I want jet numbers for the change of model etc. It all seems to have disappeared from the web sites as the the differing companies jump on and off the manufacturing of these carbs.

Graham,

I have this

Aircraft Carburettor Service Manual FAPCO-1 Sept 1984

I also have similar for Strombergs.

I do need an email address though, hence the PM

I have a list of the contents of the Kelly Quick Kit CF286-02 which gives description of part and part number of all the consumable/wearing parts. This was for a full repair of an O-200A 10-4894 carb but this kit covers 15 others too.

If anyone else wants this, pm me and I'll send a pdf of it.

I also got the pepper pot main jet nozzle (part CF47-850) which gives much better fuel atomisation & distribution particularly with the one piece venturi.

Regards
Steve

Guys,

Does anyone know the difference between carb part number 10-4894-1 and 10-4115.
Is one an updated number from the other, or do is one for the C85 / C90 variant? If different, is the difference the jetting?

Thanks

Gavin

Looks like both 4115 & 4894 carbs are for the O-200

See
http://msacarbs.com/pdf/MSA-7.pdf (same replacement main jet nozzle is applicable to both 4115 and 4894)

From this
http://www.vg-21.org/adnote/69-24-03.html

it looks like the 10-4115 may have been fitted to early O-200's and 10-4894 to the later ones.

See this too

The individual carb parts do seem available (if a little expensive!) on their own from Kelly Aerospace at least - see here

Kelly do the pepper pot nozzles for both the O-200 (MSA-7 ) and C75 to C90 (MSA-9).
