Also you need to temp it at the plug.

anyone running the 3 port r in a buggy on an outdoor track? our outdoor season is getting ready to start and i have run about a gallon through mine on our indoor track and it flat out rips!!! running a jp3 pipe and 13 tooth cb i couldnt ask for more but am wondering what to expect on the bigger outdoor tracks this spring/summer here in ohio. maybe go to a 14 tooth cb? i dont want to lose the low end it has now but dont want to wind it out too hard either. any thoughts?

just put my new 3port in my car looks sweet!

Thanks for your help mate. Guess what it was a Duratrax temp gauge. Well won't be using a temp gun again. Back to the tried and trusted method, Smoke trail, Spit and sizzle, glow plug check, ect ect.

Yes it was tempted at the plug.

Thanks for all your help folks kindly appreciated.

You can use a temp guage it wont hurt, but its good to have soemone elses to compare it to. The odonnell temp guage is one of the better ones on the market.

for those running the 7 port in a buggy, what clutches are you using, i was thinking of the werks clutch and trying a different combination of shoes but still not entirely sure what to run.

the new 3port looks good!

Started my 3port today for the frist time and wow it has a lot of pinch! looks sweet in my car to, how is every one likeing there 3port?

i need GO decals:cry:

Sounds like the LSN might be too rich and the HSN too lean. The 5 ports like a fairly lean bottom and slightly rich top - not sure if the same applies to the 3P R. LSN being rich will keep the temps down when your running in, as you never really get on the HSN under half throttle. Then you lean out the HSN to get the temps up, but it is already correct or slightly lean, so you end up lean bogging and starving at higher revs. Try leaning the LSN some and check idle gap is .7 - 1mm only, no more. Hope this helps :cool:

I have the Go 7 port and I am using Mugen aluminum shoes with 1.1 springs. This helps to increase the bottom a little bit more.

Turba Head tuning issues
 

Hi guys,

I am a newbie to nitro & I have been running a GO 5 port for the last couple of months. Recently, I installed a turbo head button & was pretty happy with the increased power. However, I have run into a little tuning problem. After running for a while, the engine sputters & there's even a loud 'pop' from the exhaust. What could be the cause of this? I measured the head temperature & it was less than 100 deg C. On top of that, I am getting 'sticky throttle' in that the engine is slow to rev down. I know that without further details, it's not easy to figure out what is (are) the problem(s) based on this simple description. Some educated guess would be appreciated. I have just changed a new fuel tank & new tubing because I was getting the 'sticky throttle' earlier so I hope that potential area of concern is eliminated.

Can't comment on the "pop" but regarding temps you are rich with it. For the slowly decreasing idle you should check your idle gap. If it's been rich on LSN and you've compensated it with increasing the idle you might end up in situation like that. Ifä you'r lost on settings a good way is to set the idlegap and then needles to the default position and start going from there. Might be annoying but in many cases provides a faster way to the proper results.

Hi Poinas2,

Thanks for the quick reply.

sounds to me like your rich down low and your idle is to high to compansate try setting the idle gap back to about .7mm to 1mm then retune the LSN hope this helps
