if you buy the the carb restricter kit you get all 4 them alloy ones and they all come with the orings check the web site MM

mattwoodcraft yes all 4 are alloy and they have the orings on the outside already

I have a couple 4 pc. sets of restrictors, $14.00.

I also bought the set of 4 GO restrictors probably 2 years ago and mine came with O rings but they were too fat...Had to rob the thinner rings from various RB and other plastic inserts I had lying around..Otherwise I couldn't get the inserts to fit in the carb mouths..

i have 4 sets of the alloy carb inserts some of the i rob the bottom oring and use it as an extra around the carby neck but i havent had any troubles with them pushing in .... abit tight at times but they do go in

Nah mine were definitely the wrong size..the O-rings fitted to the original plastic insert worked fine..hardly a catastrophe at any rate although I remember being less than impressed at the time..

here is my losi with 7 port engine

i raced last weekend in welden an was 10 th in the finale because after a jump my engine damaged at teh motormount

last week i tried the RB 2045 on my go, it was the best thing i ever do. try the rb 245 on your go and you will see what the engine can.

1 day before the race began i have the RB WS7 II 3X in my losi but the go was more powerfull from bottom to top

another victim of "obi's mega wahnsinnssprung" at the welden track

first time trying the 3ptR ....man im impressed ...loved my5 but i think this is an awesome buggy mill supersmooth powerband good top 2 bottom really impressed with the top also i didnt think it would pull that hard w/ 7mm res and DYN 086 i was wrong

heres a pic or her mounted

could i get away with running a Go 3R engine with an 053 in a D8T? I realize this wont be the best setup but its what i have at the moment. thank you for your time

LISTEN UP EVERYONE................

If were thinking of getting one on the new MG66's............ order now.

We have just run in one of these engines (3 x 5 min runs @ 90% race tune) and on the 4th tank we got a run time of 11.30 PLUS ANOTHER 3 MINS AT IDLE IN A BUGGY

The performance was awesome. We have always been happy with Mark's modded Go-Techs, but these engines are on another level again

On top of this the above run times were achieved on MM HB444 fuel and we about to switch to the MM A MAIN BLUE DOT, which should improve run time even more..........

Truly an awesome engine guys............

i run the 3 port in my buggy with the dyn. 053 and love it. i am way impressed with the 3 port . it has more power all around than my os speed. great job to go engines!! i am sold. i did end up changing the carb right after break in to a +21 novarossi carb no lean bog at the bottom and cooler temps. my carb was weeping from the casting where the main gose in, but at the price i didnt mind swaping the carb.. it should be fine in your truggy..
