Rate my idle. (Edited to add video link)

I know it’s some what subjective, but tell me what you think of the idle. It’s a Losi 5T 2.0. Zenoah 320. The primer bulb is always completely full at the moment. Needles on the carb are at factory settings.

Sounds good.

Use that air box with caution. They have been engine failures with them.

From too rich or too lean?

Idles very good.

Get rid of the tr airbox and the spider filter.

Best combo is this.

I lost 2 engines that were on their first run in's... don't make my mistake

 

[codeman11]

What air intake is that, and what's the issue? It has a leak or something? It looks like a nice billet intake to me ..

 

[Rep732]

It's a 2 piece intake, the 2 halves are a tight fit with a thin o ring. My last engine that sucked in dust and sand the o ring got pinched when I assembled it.

 

[Picodogg]

I ended up lobbing some heavy bike chain grease on the o-ring. My worry when assembling it was what you are saying happened to you. Great Knock on wood I guess.

 

[Rep732]

I greased mine too .. good luck

I have 2 new tr air boxes I’ll never use. Just not worth it for me.

 

[Picodogg]

Guess I might just add some of this seal all stuff to my next DDM order and see if I can just completely seal the air box?

With that said… I hope Discount Dave has discount children I am helping through discount college with the amount of money I have spent at DDM’s online store. Don’t get me wrong though, they have wonderful service.

(Hey DDM if you see this please send me a discount code.)

 

[Rep732]

@Picodogg the discount code is (5SC). It's not a secret.

Thanks. I will use that.

I should have searched the forums, but didn’t even think about it. If there wasn’t so many goodies to buy I would have been more focused.

I was about to say, I'm sure you can seal that with some Permatex heavy duty gasket maker and seal, and put the o-ring in, and put a decent amount of gasket maker into the grooves and problem solved. Should really do that with all the air intakes designed like that I'm sure; it's a nice design in that it gets the air intake out of the way of the cage or keeps it tucked somewhere not in the direct line of dirt.

Good to know though for those who have one to seal it up properly and not rely on the o-ring.

 

[Picodogg]

I think I am going to just make several passes on the outside rib where the box comes together. My fear being that if I do it on the o-ring on the inside it will never come apart because it takes acetone to break the material up.

I am guessing it will be a maintenance issue based off @Rep732 ’s experience even with reapplying seal all every so often.

 

[Rep732]

In order to get the bolts out that holds it to the carb you have to split it, generally there's no reason to seperatethe halves once together. Also depending on air filter it hinders your ability to put the gas cap on.

Ah this fight again.... the 2 sides need sealed with rtv... ran one for years on the dbxl and have had zero issues with the one on the 5ive t...... also proven they flow plenty for these engine.....

What’s RTV?

Edit: Room Temperature Vulcanizing

Word.

That’s the way I am going to proceed. I like the design and layout of the box. I will just give some service to maintenance for the time being.

For what little I use my engineering degree; I totally agree on the airflow. Anymore CFM on these engines and it will just blow the oil/gas out through the exhaust.

 

[Seandonato73]

Thats not quite how engines work... I wonder if you degree was in quantum physics and not so much mechanical engineering...
