R/C Tech Forums - RB Concept Engine Thread..

no no no no. Not the big orange thing that looks like a fuel filter. But in the smaller plastic pieces. There are two of them. One has a nipple on one end the other has two nipples, one on each end. They are flat and round and look like a single round fin with small hole in it. These are what I would assume are the dust protectors but not sure how they mount.

Well I bit the bullet and bought a Shark 10 from absolute (price was AWESOME for engine/pipe combo) and it came with the RB gas cooler. In looking at the package for the cooler everything looks straight forward except what I can assume is the "dust guards". They look like they press into SOMETHING and have 1 or 2 solid nipples on them. Can anyone shed some light as to where they go and what they really do???

They are fuel line plugs. I use the double plug when I remove my engine, to keep crud out of the lines. The single one on a small piece of line to keep the fuel nipple clean.

RB's part #1258-9B 9mm or 1256-8 8mm carbs are good choices, so are the Novarossi's part #24063 9mm or 24060 8.5mm carbs.

If you can get the newer style B10, or Shark RB carb, they work the best, any of the new Nova Rossi carbs will work also.

Is it true that a nova +4 connecting rod will fit a ws7 L2g.

No it is not true, the crankpin on a Novarossi is smaller than the crankpin on an RB. It is possible someone had an old engine with a worn WS7 crank and the Nova rod was able to fit on a worn crank, but I would not try it.

hi guys... I recently bought a shark 10 for my buggy... its the very first time I ran RB... would like to know what is the time to change the rod...

planning of putting ceramic bearings after break-in and the changing the rod at 4 gallons as I ever do with the os, werks and nova... by doing this how many gallons of fuel would I spec the engine to run 8, 9, 10?

thanks

After 20 tanks with the head wrapped do u guys pull the wrap even if there is still a metal pinch.

GarrettMcKamie

04-10-2011 09:37 AM

Yes you can pull it off. But be sure to heat it up before every tank though.

segreda...after it loses the metal pinch around the 2 gallon mark would be the best time to change the rod. Randy here you go http://www.amainhobbies.com/product_...-Crank-Bearing
