Could I just get a shorter one by traxxas because thats all the LHS carries.

The only thing I can think of is bring a #8 plug that U know works and compare it to what they have in stock. make sure the thread pitch is the same and all that happy stuff.

DarkFire989

Alright I might as well go make a trip to the LHS. Hopefully they have something.

good luck, my hobby shop is no help to me. That's why I joined this forum. They only have rc guys in when I can't get there[:'(]

One thing you will want to keep in mind is the heat of the plug, if you get one that is not comparable to the os#8 you will have problems starting and keeping it running... You will have to break in that engine since it has new piston and sleeve, it is now a new engine again

Here are some pics of my needles

I wonder why my HSN is so far out with the primer pump installed just to run 240

The Real Dogman

Could be your climate, remember, I'm at 2600 feet above sea level and hot!! thin air...

DarkFire989

The plug i got was a traxxas standard (hot). Isnt the os 8 plug also hot?

The Real Dogman

Dunno never used Traxxas Plugs

DarkFire989

alright, with giving it a little throttle i can get it started, but it wont idle, i have to keep my finger on the throttle just abit to keep it running, i have my hsn at 3.5-4 and my idle is pretty high. what should i do?

SOILWORK

You are using the wrong type of plug...Bigger engines require a medium to cold plug while smaller engines need a hotter plug. The OS#8 is a medium plug..your ploblem could be from using the wrong plug.

DarkFire989

Ah really?[] I just bought that plug. Is it possible that the fact that the fuel line running from the exhaust to the tank is a foot long( i had no other fuel lines so i took it off the revo.

but the os8 and a3 are hot/medium plugs [link]http://www2.towerhobbies.com/cgi-bin/WTI0091P?&P=SM&C=GME&V=OSM[/link]

SOILWORK

It could be...trim it to the proper length and see what happenes...I still think you need to get rid of the traxxas plug....using the wrong type of plug can cause overheating. Get a OS#8

I just found this article on pressure line lenght

Yeah with an OS#08 you know its the right temp plug. Sorry you just went and got it, but..be patient.. Order more than 1 for later

The pressure line should not affect the idle as much as the plug and your low speed mixture. But the Pressure lne should only be as long as you need to get to the tank.

When you took out the valve did you reset all needles to factory settings??


EDIT ADDED: Good Find On That Pressure Line Article Never Saw That But Is In Line With My Thinking

DarkFire989

yes i did.

Ok then, you need to determine if the rough idle is from too much fuel or not enough.. Stalling is common with new engines that require break in.. Have you decided how you are going to breakin the engine, Heat Cycle or idle thru tanks??

DarkFire989

I guess im gona have to order another 3 plugs off tower. I wont get them till the end of this week... Hopefully. But i start school wed. []

Edit: im just going to idle through the tanks.

The Real Dogman

ok then, when you get your plugs Holler back and we can get your tune better to it will idle right, without right plug you are just wasting time.

Here comes another 15 bucks out of my pocket I need the money for gas but i want to get this truck running!

The Real Dogman

Good to see you priorities are in order!! lol

DarkFire989

Haha, I just want to play with this thing. Wanting it all summer only to get it when there was a engine problem made me sad, hopefully this is the last problem i have with this thing.

My Feedback: (2)

Here are a couple of pages that may make picking a plug eaiser - or at least better to understand what plug to pick.
