Revo 3.3 Seized

[CreepyQuarryCrawler]

Yes! We're getting closer. I had to raise the idle and lean the low needle out almost all the way for it to be happy.

Still doesn't seem like it's shifting or wanting to shift. I'm definitely nervous about over revving it again.

I was just going through old 3.3 threads, I want to do this thing up now LOL
Camme across this video, saving it here for later

What temperature are you running it at?
How many tanks have you run through the new engine?

I just finished tank 6.
It's running around 220-225f

Just like religion or politics, the engine beak-in procedure has many true believers harboring a variety of "personal truths".
I use a stepped approach and personally, I'm shooting for 200 F during my 6th tank, but I can't find fault with 220.

I also use a stepped approach to the trigger, starting with a full tank at idle and no resistance to the wheels.
When I put the truck on the ground, it only gets short blips on the throttle for this next tank. Just enough throttle to keep it running.
Tanks that follow up get slightly more trigger time (and higher target temps), until by the 8th tank, it's basically WOT and driven hard.

Every engine is different, and given the impact of gearing and shift settings, I can't say exactly which tank in the break-in process that I would expect to start to hear a truck shift, but I'm generally not envisioning giving the engine enough sustained juice (thus operating temp / rpms) to expect it to initiate shifts until about the 6th-7th tank.

@ohsnap
Thanks so much for the information!

I am completely new to running Nitro. I wasn't really aiming for a certain temp, only to ensure I had it above 210-215f which I think is in the TRX manual.

I was able to get tanks 6-7-8 done. I have been doing everything by feel and ear.

I need to spend more time tuning but I am really considering springing for the OS carb.

Here's my run this morning;
