ATV: 2005 Arctic cat 400 auto
2007 400 auto Carb work on a 2005?
Good day! I purchased a 2005 arctic cat that needed some work and hope some of you could help me out!
Does anyone know if a 2007 Carb (0470-667) would work properly on a 2005 (0470-470) 400 auto?
There are some slight differences when I looked them up on the parts Diagram:
Vacuum piston spring (#3 on parts Diagram): 2007: (5507-173) 2005: (5507-085)
Needle Jet holder (#8 on Parts Diagram): 2007: (5507-174) 2005: (5507-047)
Main Jet (#9 on Parts Diagram): 2007: Main Jet 135 (5507-057) 2005: Main Jet 142 (5507-043) - The 2007 lists the Main jet 142 as a part available with two asterisks**
Float set Valve (#12 on Parts Diagram): 2007: (5507-183) 2005: (5507-107)
Float Chamber (#27 on Parts Diagram): 2007: (5507-181) 2005: (5507-065)
Float Chamber O-Ring (#28 on Parts Diagram): 2007: (5507-207) 2005: (5507-067)
Diaphragm Assembly (#31 on Parts Diagram): 2007: (5507-182) 2005: (5507-031)
Everything else has the same part numbers listed for both.
Reason why I am asking is the fuel leaks steadily out of the overflow once the bike is turned off. I took apart the carb the other day and cleaned it out, there was quite a bit of black particles that came out but didn't solve the problem. There also seems to be some copper components inside that have corroded over time and left a green residue from corrosion I cleaned it the best I could but some still remains in hard to reach places.
Also the previous owner mentioned he put a carb kit in it but when he installed the cover for the vacuum piston (#1 on parts diagram) he must not have seated the vacuum piston diaphragm in properly as there is a small rip in the diaphragm on the piston (#4 on Parts Diagram) where the cover pinched the diaphragm. I think this is fairly common mistake as the diaphragm seems to stretch over time making it hard to seat properly, he must have tightened the cover down with it not properly seated causing the rip.
The vacuum piston is about $85 alone, and I can get a brand new carb from a 2007 for $195, and I don't believe the vacuum piston would cause the fuel to stop leaking anyways. I believe they are both (2007 & 2005) CVK 34AE carbs. I'm thinking if the carb would work it is worth the extra $110 as I would have some spare parts to use in the future if needed (the electric choke for example is around 150 bucks and from what I hear they fail somewhat frequently)
