are you measuring with insert in or insert out ? and if its out and .5 wont fit then yes open the idle gap...and if it seems lean fatten it immediately !

shein95 06-27-2015 05:51 AM

Yeah, insert out.

It was lsn way too rich, hsn lean. Classic with long lsn carb

I need help here guys.
Drove my new HB car today at a race and at one point lost the air filter and ran without it for a few lap (It was very well held with a zip tie).
The car stalled a lot too so I though that I must have killed it :(. Most the time at the end of the long straight.
I checked the intake of air with and earbud and it was fairly clean. The motor was a total pest and would just stall and stall when touching the throttle. I was super worried.
Eventually I tuned the motor with the help of my mate were basically we had to lean (a LOT) the HSN and LSN. Then the engine behaved itself ok (before that the car was spitting an awful lot of oil).
I had a hunch at the time (but couldn't test it as I didn't have one in stock) that it could be a bad glow plug choice.
I always run a C6TGC plug and today's weather was quite hot, about 100°F (35+°C) and I think the glow plug was too hot. Am I correct thinking this?
My second problem is that novarossi's glow plug are now getting very hard to get and all LHS don't sell them anymore I might go with OS plugs... presumably it's a one way ticket but as long as it works I'm ok. What would you recommend as next week's race will possibly have the same heat conditions ?

thanks very much in advance

Ps: I'll probably have the tear down the engine to clean it and check the dust if there is any :(.

I wouldn't use anything but novarossi plugs. The mesh of the thread aren't the same as OS plugs and could damage your head

Any pipe recommendations for a Novarossi BT5 engine?

bash bros 06-28-2015 07:53 PM

So is the Ofna 053 a bad pipe for the p5xlt or did I just get a dud?

I could not tune it for the life of me with the 053 on there. I had to run the LSN lean just so it wouldn't bog down during takeoff. There was hardly any balance between rich and lean with that pipe.

So I threw the 2096/41021 on there and all the tuning issues dissappeared. I was finally able to richen the LSN back out to where it should be and finally got a nice consistent idle.

Maybe I'll try the 053 with a different header and see how it does. That pipe did have a ton of mid range torque though, I could pop wheelies with my mbx7t when I could actually get it tuned decently.

Socket 06-28-2015 09:15 PM

The 53 pipe sucked on the P5 as you've found.

If 053 sucks then u have to check ur tune

Hoese37 06-29-2015 02:54 AM

As for your plug choice, you ran the correct plug for an off road engine. If you need alternatives, the O'Donnell plugs are nova clones. The 97T is a great choice.

Lille-bror 06-29-2015 05:43 AM

I dislike OS plugs in Novarossi engines (and they fits just fine in them). In my rather old BTT, I struggled with load up even though I ran a new P3 plug. Thought the plug was the ok for the engine so just kept running it (Cold weather). After ½ a liter or so the engine stopped and couldn't start again. Fault: broken coil (didn't dropped down in the engine). I then found a used OD77T plug and the engine ran FLAWLESS after that. Such a big difference!

Really? Hmmmm i guess after all these years i better rethink how i do it huh, thanks for the info :rolleyes:

counting the turns is the only way to get an accurate setting , flush and flush could be off by as much as half turn on top and a full turn or better on bottom . Granted the engine will have to be properly tuned in any case but counting turns from bottomed out is a precise method of setting the carb

btw you better email novarossi and most other manufacturers to stop setting the carbs like that at the factory ,lol

I have rb2097 pipe with a extra short manifold, will it be a good combo for 4btta? I do have other nova pipe 9901/9886/2096-41021. Any of this pipe similar to it?

klujan1001 07-01-2015 11:18 AM

I really liked the Orion 2058 with the btt the 9886 will get the most power with the least fuel mileage the 2096 will be the smoothest with best fuel mileage

It will work great, but you would probably want a longer type manifold for tracks with bigger jumps.

How is the top end of this pipe, i find 9901 lack top end combo with btta

What is the best break in procedure for a P5XLT and what % nitro should be used?

Fuel that u will use after break in. 25%@30%, but i recommend higher lube %, byron speed blend with 11% lube

gablett 07-02-2015 11:57 AM

Searched a bunch and cant seem to find the answer Im looking for. Whats my best bet for pipe/header on a TNS Legend .25? I have a dynamite 086 I was going to run but not sure thats my best option. Its going in a Kyosho ST RR Evo. Thanks for the help.

There is a great break-in thread at the top of this forum.

I am sure if you PM Maximo (Neal) He can help you out with his motors.

2096 is a great all around power pipe thats smooth and has good mileage I hear. Pair that with a 41021. For even more RPM you can go 9886. Hopefully others chime in for some more suggestions as I know this is for truggy

Maximo 07-03-2015 04:55 AM

9853/41001 will give the best power and RPM.... 2096/41021 will neuter the engines power, probably one of the poorest performing combos you could choose for a .25..........IMO stay far and clear from a 2096/41021 combo on the .25 unless you want it to run more like a .21 then a .25

houston 07-03-2015 08:14 AM

So ,i got some of the new c5tgn plugs coming , supposed to be "the only plug for all occasions" according to novarossi . We shall see ,hope they are as good as advertised

For now im still using c6tgc after break in , cold weather c5tgc

Happy motorin'

And for the record 9853 with 41001 ,41019,41005 is a badass combo ,been using it on truck for a few years, glad youve seen the light Neal ,lol

2096/41021 is still an awesome power delivery for buggy though

Let me know when those plugs come in. I want to try them out as the c6tgc has been my all occasion plug.

What other pipe recommended to use with 4btt engine? Fuel economy n powerful then 9901/2096.

beidle99 07-03-2015 11:41 AM

The 2058 pipe is a good inbetween for the 9901/2096.
Bottom end similar to 9901, top similar to 2096. But not as much on gas milage

Yeah I kinda want to give it another go because that pipe had ridiculous low end and midrange in my truggy.

I wonder if using a different venturi would help with the tune? Like I said it seemed like it was either blubbering rich on bottom or too lean and would start surging at idle.

7mm instead of 8mm maybe?

cczjordan 07-04-2015 05:58 PM

4btta/9901/41021
 
I bought a used btta with this combo and the compression is really low which will die when let it idling. The engine lack power but runtime is excellent. Honestly is the cocompression low or it was design to have less power?

cczjordan 07-04-2015 11:09 PM

Looking for replacement piston/sleeve set, so many version of 4 port, which is the best? All have same dimensions?

TRUGGYRACER1 07-12-2015 02:31 PM

Hi how are you, go the Buku web site (type in Buku in google) they sell the cap for the front of the engines, I have used them great idea -- Rob

rptech1 07-12-2015 09:41 PM

Hi all,

One question in regards to crank timing - looking at the crank in your hand - with the connecting rod end pointing toward your body, is it the left or right side (to grind) to produce additional power...

Gavel 07-12-2015 09:58 PM

what mid price engine/pipe combo would you all recommend for a buggy and truggy. currently running Reds stuff, and while its excellent its also very expensive. Thanks all

Hi mate, I recently purchased a RB from East Cost Hobbies, fantastic engine and a great price... Rob
