i bought 50 of them with no problems yet. i havent had one blow yet.

+1 on that.

RC retailers here bought heaps of those plugs (like around 1500 or so combined), and no complaints from any customers.
The 97T rules supreme here !!!

+2; at the moment, 37 degrees C, 84% humidity, and the 97T still keeping tune. Have also run them in a Nova Rossi Buggy 4 Factory Tuned, and no problems.

Hmm - that's a little uncomfortably warm and sticky Snooks, but I guess you are used to it huh. Did you track down any 3 needles over your way ?

where can i get the best deal on a motor pipe combo for a 1/8 scale buggy?

nitro-north.com....give matt (motomatt on here) a call...his prices are AWESOME!!!!

Gotta love summer in Far North Queensland. Haven't had a reply from MM on the above. Have tried phone and emails, but no reply. If you can arrange 2 carbies, that would be greatly appreciated. Send me a PM if needed. Thanks again for your help.

Hi Shane,
you have a PM. Thanks

I have the Go GX11-5RHO, done about 3ltrs of fuel and since new it seems to leak fuel behind the flywheel, every time I pull the motor out there's wet dirt behind the flywheel on the block.
Any sugestions as to what might cause this leak, also since new its been a bit temperamental to tune, I thinking this leak has something to do with the tuning issues. Is there any problem that can occur tighting down the flywheel, a guy that knows alot about Go engines mention when tighting down the flywheel to take out the freeplay when pushing on the flywheel collar.
Any help appreciated.

Mine was the same way. I took the seal out of a front bearing I had replaced and installed it into the bearing that was in the gx engine. solved problem. They only have 1 seal[outer] 2 seals worked for me. Or just get a new bearing with double seals.

all mine did the same thing, when running rich some of the extra fuel is forced through the front bearing, that may be your tuning issue. i replaced front bearings after break in (well, i dint, sent them in) and have no problems since.

most times the fuel can leak if the engine just sits with fuel in it...if the bearing isn't spinning it isn't making a seal....when the bearing is spinning it creates the seal ...the rubber shields are just to keep dust and dirt out of the bearing, they do nothing to really "seal "the engine

If your having tuning issues replace the front bearing. As the guys have said, this is most likely your problem.
With the collett, it should pull the crank up tight against the main bearing as you tighten the clutch nut, but it is good practice to remove the back plate and actually push the crank and hold it against the main bearing while you push on the collet and nip it up. This alleviates any chance of crankshaft movement, and the con rod scraping on the back plate during operation.

Have you guys got the 3 needle carbs in the US yet ?
Interested to hear some feedback.

Not that i know of....alot of the big name team drivers dropped off and are no longer running go engines except us die hards...i have had no issues with my go motors ,but ive been running alot of 10 scale electric lately lol....i still go out and practice every once in a while with my truggy and it doesnt skip a beat..... Ordering up my Agama buggy for the new year and will be running my gxii....cant wait.....have heard alot about how the stock gxii carb restricts alot of power and whatnot.... Not mine lol...i run it in a losi 2.0 truggy with a 6.5 restrictor and the 2072 pipe and its awesome....even guys had trouble clearing a certain tripple at this years nats with the gxii and all motors but the os speeds ofcourse ,in buggy or truggy...i had no problem clearing it at all in my truggy....i will most likely continue to run go engines in 2012 as long as i can get them cheap
