OS MAX 21 XZB
Hi
I have a OS Max 21 XZB in my Jammin X1. The engine is fully broken in and runs great I was doing so much needed cleaning of the aircleaner assembly and I noticed that the yellow carb insert has a blue discolored streak that runs from the top to the bottom and when I first took it off it appeared that that there was a puddle of blue oil at the bottom. I am using powermaster 30% nitro fuel which is blue. I am also using red foam traxxas foam oil on the airbreather foam. The engine is running great I have no issues with what so ever but I was just concerned about this blue streak. Should I just replace the carb insert and use less oil on my air breather foams? Thank You Michael Johnston

RE: OS MAX 21 XZB
Sir
I really appreciate your quick response! I bought this engine from an guy and I had to replace the plastic carb insert but rather than that nothing else. I did notice some rust streaks on the crank shaft and the counter balance but this engine just RUNs so I will just keep feeding it fuel!
thanks

RE: OS MAX 21 XZB
I see where OS has released a new 21 called the 21XRB and it says in the press release that you can upgrade it with XZB parts. what parts are they refering too in this ad? Also I noticed it has different carb the 20b and the xzb has 21j2 and is there a difference in the size of venturi? I need a second engine and I found a brand new VZB21 at an LHS and the price is good. Are there replacement parts available for this engine? Thank You Michael J
