RB Concept Engine Thread..
#1593
You can always peek in the JL .21 thread in here as they are basically the same engine. A lot of guys have been trying different pipes and head shims in theirs but I have not kept up on what people like the most.

Well, I've been doing this little standard trick with the spring since I started
with nitro in the 90s. Anyway. what I am finding is that the shaft is not sliding
quickly enough to close the throttle. The shaft is straight and the hole where
the shaft mounts on the servo horn is also free. Looks like the carb is not
allowing itself to close quickly. If I push with a finger, then it closes quickly, but
if I close with the servo, the linkage stays out and slowly goes back in.
Hmm. I'll readjust my servo horm to be 1 slot off and that way I can put more
pressure from the spring without loosing brakes.

Man I wish, I just had surgery for a hernia and it really put me outta commission!!! I did not expect it to lay me out like it has. My daughter lives in Anthem, Az tho so I will be making several trips out there this winter!!!

Sorry to hear of your surgery, it's not fun, I had that, about 10 years ago, what a nut buster! Good luck.

Find them much better than throttle return springs.

i have a question about sealing the carb on a rb im using lucky 7 sealent are you supposed to seal above the carb o-ring or the bottom ? i used the sealet on the top and slided on the o-ring while it was still wet not dry and mounted the carb. i only used a little bit of the sealent.

cdc on here said to remove a shim to run 20% with a hot/meduim plug what do you think of that will it do any harm ? the s5 has 2 shims on it already but it hasnt ran right with a meduim plug so i was thinking there was a leak.
the shims are .20 mm.

well i dont think its a leak and the carb o-ring looks fine its a nova carb ring its thick but it dint look damage its not old. maybe should just remove the sealent than.

Just know that you can destroy an engine if you run it while its pre-detonating.
