Go-Tech Engines Thread
Just bought RC8T with a Go .21-spec-3port engine with red head on it.Running 30% Sidewinder fuel.I'm new to these engines and am having issues and getting fustrated.After buying,I tore it down cleaned checked and rebuilt everything in the power plant.First off it starts great and idles fine.I'm having problems getting the temps up, I lean it out to get temps up and it seems to be starving for fuel and stalls out.Richen it up a little and it runs fine but after about 10 minutes temps only at 160 F it pukes the O'donnell 97T plugs that I'm using.The plugs are still clean and new looking but the wire is breaking about 2-3 coils up in the plug.
I'm hoping this is enough info for some help/suggestions with my problems.
thanks............gosharpie97.

Tune it so it's running strong with good smoke and leave the temp gauge in the tool box.
It will run at the temp it is happy at, and all motors are a little different. You need to be tuning the motor so it performs well, not so it runs at a specific temp or temp range. From what you are saying it is too lean on top - hence the bogging and fuel starvation, plus the blown plugs maybe.
Set your needles as Matt has suggested and then tweak the bottom end first, then the top for max performance and leave that temp gauge in the tool box

Here's a sort vid of Kendall at the Mnrc round 2 last weekend. Kendall's Go 5 ports ran awesome, lots of people were having tuning issues with the sand and high temps and humidity. Kendall won Buggy, Truggy and Short Course.

run right in the Nova engines either. If you don't believe
me. Ask the Nova guru on this site why he won't run the
Nova plugs and doesn't sugest running them in the Nova
engines he sells.

At 20c weather on a race tune I cant get it past 230F even if its running extremely lean.
My LRP .28 on the other hand runs rich at 260ish.

If the needle is tapered to a point and still remains in the receiver jet opening at this throttle position - you have the long needle.
If the needle withdraws from the reciever jet at around 3/4 WOT and has a rounded tip, then you have the shorter needle.
Shorter needle will tune like most other carbs. Longer needle is quite different and requires the HSN adjusting screw to be pretty much flush with the brass tube it sits in. For details on long needle carb tuning visit the tech tips page on our web site at www.go-racing.co.nz - you will find a step by step guide to getting the long needle carb tuned in there, if thats what you have fitted.

See pics below for different needle comparison. Pics are not to scale, but the long needle (tapered tip) on the left is 1.6" long and short needle (bull nosed tip) on the right is 1.42" long.
If you reference your needles as turns in from flush - rather than turns out from fully screwed in, you won't run the risk of screwing them in too tightly and damaging the tips of the needles. Just a thought

Not to take away from GO at all. I actually really want to try one of the newest ones.

Sorry if I hurt your feelings Ryan. I was just relating
my opinion of the Nova plugs. Also what was said to
me by one of the top Nova gurus in the U.S.of A..
I have tried running them in Nova,RB,MR,O.S.,GO,
Picco and JL nitro engines. I just don't care for them.
I also usualy run a colder plug that most do in there engines
and consider my self a pretty good tuner.
Some of the guys on here are having trouble getting
there engines dialed in and I just don't think a Nova
plug is going to help make it any easier for them.

Oh, my feelings arent hurt. Simply stating my experiences. Ive ran plenty of novas and never have once had a plug run better in one then the nova plugs. Maybe its just me? Ive also never seen any other plug reccomended, maybe im talking to the wrong pro's.
With that said, it is very possible (and obviously so) that the GO motors dont like those plugs and run better on something else. Maybe i'll order one and find out!
