i have no clue, RB went through a mix and match phase of many engines, mainly the rally and V series... so its hard to tell unless you can find the parts listing your self

Need help diagnosing what's causing my franken S5 to die when I lift the rear end of the buggy. I can make it idle normally but it dies once I release the throttle for example to enter a turn, if I raise idle then I have to raise it way too much. Running Model Technics 25% and 6.5 venturi and 2058 pipe. HSN is flush, LSN is quite a bit in (4mm or so from flush). Engine clears OK, smoke trail... I think it is getting flooded but afraid to keep leaning the top.

No leaks anywhere, fuel delivery is OK. What caught my attention was that the venturi was dripping (a couple drops) fuel once I removed it.

*edit
Today was the same without the venturi. I saw fuel on the exhaust pressure line. The fuel tank lid isn't sealing apparently.

Hey how's it going guys, I have a rb bxr sls3 engine. I just cracked the top cooling head fan off and I took apart the engine to check the internals also. It looks like I need a new rod also. It has a lot of play in it and I don't wanna blow it up haha. Anyway does anyone know where I can get rb engine parts for this engine. Searched a little but I'm still at track now. I'm trying to see if it's worth replacing the parts or just start using another engine. Any help would be greatly appreciated! Thanks

As far as I know they are out of business. You are gonna have to look and ask and see if you can find what you need

Maybe ask in the Novarossi thread...(since RB's were made in the Nova factory...)

Thanks yea I came back in this thread to post that maybe nova rod would fit. Head I might not be able to get that. But I could use it with a cracked fin. Thanks

I believe the crank pin is a different size on a RB engine.

Yes it was/is, 1mm less if not mistaken.

Thanks for heads up, I took it completely apart. Rod isn't that bad actually. The rear engine bearing seems to have a lot of play in it. I think if I replace that I'll be good. I gotta figure out what size bearing to get for the rear engine bearing. Anyone know what size it is. I'll take it out and measure it. I would like to get another head if there cheap. Probably won't be able to find one.

I remember reading a post by Maximo that owns tns and he said the drake engine uses the bigger Rb rod and they still make that motor ! Get in contact with novarossi USA

Pretty sure most nova heads would work. Should be able to pick one up off of fleabay pretty cheap.
