It is not as you need diffreent carburators, you do not need different shockpistons either, but it is nice to have as a tuning option. Just as pipes/manifolds and venturies. The more knowledge you have the more you can make out of enginetuning, just as you have on chassistuning.

I think the current carb is great, personally.

The three needle carb can be very useful to some. The other one almost looks like something they would put on an RTR engine.

P5
 

Question

I have a BTT turbo button that I want to put on a P5 to replace the standard button. Anyone know if it will fit? The BTT Button appears to be deeper than the standard button. Anyone know the correct shimming to compensate?

Hey guys I need some help
I have a btta that has about 6 gallons on it
The lower my fuel level Getz in my rank the shorter my engine will idle before flaming out

It has a small amount of mechanical comp
I put new button and plug new fuel lines new clutch etc
I've tried a few different tuning things
I've got two copper and one silver shim
It will come in perfect temp nice amount of smoke
It will stay running if I blip the throatle but will die under one quarter tank in 4 to 5 seconds arfter coming for a stop
However over a quarter it will idle probley

It doesn't lean bog drives smoothly etc

May pay to check for an air leak where the fuel nipple goes through the tank. Had a similar issue that I chased my tail with until I noticed it was happening when the fuel level was below the nipple. Hope this helps

Yeah try a new tank and if that doesn't fix it, get a light pinch done on it. I had a tank with a tiny crack right at the seam. It was so small it didn't visibly leak yet as soon as fuel level fell below it, the tune changed dramatically. I only found it by pressurizing it while holding it under water. New tank fixed it up.

maybe time for a repinch....who knows maybe the engine has has some hurt inside that you don't know about

Everybody hurts...sometimes...so hold on:lol:

Sounds like a pinch is in order. As the engine gets hotter the seal loosens up between piston and sleeve. If you really have 6 gallons on it, then i would have it pinched by a professional.

Yep
 

I agree most likely a pinch, but do check the glow plug and make sure it's the right one for the engine. I find the 4 ports like a slightly warmer plug and to not have a low idle. If you make the idle perfect it won't be after a few tanks and or a low tank. Bearings- I've seen some crappy bearings in the last year or so. Mostly rear ones. fuel tank- I had some issues on my mbx-7 lids not sealing properly just a thought. Fuel- if it's good it's great if it sucks it sucks. :lol:

Yea I spat the dummy 9 months of not one problem
And now drama arfter drama
I do enjoy my ep currently
But I haven't given up though

Hi I have at least a 5 year old Top P5 engine that is need of a new crankcase, bearings and piston and sleeve. Can someone please tell me where i can get these parts? Thanks Michael J

Unless you are lucky, you're probably better off saving the carb and getting a new P5xlt

+1. :nod:

Great engines for their price range..

I've got a question. I have a P5XLT that has less than 2 gallons on it. It runs so good and so strong, I can't figure out what makes the more expensive Nova engines worth the extra money. Maybe someone that has experience with all of them can chime in.
