I have also heard people tuning with the wheels up off the ground, with the throttle pegged and they move the needle to listen to the engine and the dance between lean and rich, once they find center, they go just to the rich side of the middle. Is there any validity to that? Or does it have to be under load?

I have that exact same DBXL. Can't wait to see what you're able to do with it!

Looking forward to seeing where you guys take these rigs!

Very interesting 🤔🤔🤔 obr 357

Looking good obr on the proud 💪🏼💯

I have been waiting for this video. I think it's time for a 2nd Obr. I have really enjoyed my 30.5 fm the past 4 years but my losi needs an upgrade. Absolutely awesome stuff

Cool👍🏻💥💥

Great job OBR! As always!

nice work!

OBR's kick ass!

Awesome , great innovation in the hobby. Thanks for all you at OBR bring to the hobby

Looks good. Might grab one for my 5t track truck .

sweet! ! ! !!Im not done with my 34cc full mod yet, but this will be a wicked upgrade.

Beast mode!!

Awesome brother great work my build we done is still going strong it's a beast

Is there any plans for a twin 70 Magnum?

Awesome to see you making videos again love the work you do. Let me know if you ever want to sponsor me for one of the engines. I run a lot of the druggies and buggies one fifth scale.

Very cool, I love my OBR's! I knew they were performance made when I pulled the pull start, these engines are tight! Hours of run time later they still pull start a lot harder than my chinese motors, even the Rovan 45cc.

Nice job Im dead certain this motor belongs in my baja I hope that guy with the long white beard thingy mi bob can see my baja is in need a new motor right now 👉🏼👆🏼👈🏼 .....

Great video and detail! Also i appreciate the time and effort that was put into this engine. It runs very well. Cheers

🔥🔥🔥

awsome to see the cranks are done here in the usa awsome job on the vid

This is a true racer with that high flow exhaust can. My favorite exhaust for racing!

Hi how do you take the plate out with out the pulling tool

What the minimum squish and maximum squish recommended on these engines ?

I have an even quicker method… screw the low needle all the way in till it gently stops, and then start the engine to get rid of the gas inside the engine. When it stops running, open the low speed needle again to stock setting, and that’s that. No need to take off the carb

Crazy how this decade old vid, still helping new peeps to the scene like me! Just got a Rovan LT and fitted a Zanoah 29cc. Going well so far 😊 Thanks for this. Are you still into rc?

My gp 460 go beter

Great informative video thanks, im near London England, got a Rovan 30.5 you helped, anymore power tips?

Thx for the info and time

Where is the default idle screw position ?

8:41 I was having trouble with my 5t clone brakes sticking then I remembered something that caught my eye. The springs on the brake rods! Fixed my problem. Thank you

Hey dude I’m so glad I found this video I’ve been losing my mind on my Baja 5t I bought used that would also move the hammer when I applied the brakes. When I set the linkage throttle and balance it to how you did with it hitting the idle screw, when I full throttle on the controller, the throttle hammer does not fully touch like yours does. Now I went into the controller to check the throttle EPA and it was already full at 125. So my butterfly does not go horizontal at full throttle at all. Any idea why? I can also upload a video if you need more details!

For some reason it didn't work for me any help would be greatly appreciated thank you

what about the 813 that squirts fuel when you punch it? any difference, can it be modded to have lower psi openin?

Can you get that twin motor to fit in losi 5ive T if you can I’m gonna order one right now

Haha that’s soo cool! Balboa Park

How does any of this “Double” the power?

Need to update phone number called it then it said disconnected phone number

Bro...my baha 5b engine starts but after few seconds stalls..sometimes it gets flooded too and hard to start. I cut the fuel supply then it starts again..what could be the reason

My engine cuts off when I squeeze the throttle?
