thanks bro..by the way can u please direct me to where i can obtain the clutch system that u mentioned...(any specific website) TQVM

Yes, I am using Sirio turbo glow plugs.

Very possible. When I first got the engine, I stripped the threads the first time I put in a glow plug and had to replace the button head before even starting up the engine. Ugh! That was over a year ago.

The engine was running just fine up until 2 races ago. The race prior to that, I burned a plug because of a blown exhaust gasket - and it was the last race of the day, so it didn't really matter. So 2 races ago, no matter what I tried, I couldn't get the idle to come down right away after being on throttle. While looking straight down at the engine, I noticed some fuel "percolating" around the base of the glow plug. I wiped it, put the plug back in and the same thing happend.

I know I have to replace the button head - just wondering if anyone had similar problems. I've never had problems like this with my other engines and IMO, the glow plug doesn't thread in as cleanly.

Just fyi - I am using this type of glow plug wrench:

check out kyoshoamerica & they can locate a dealer that has them in stock or you can try to purchase it directly

the clutch system can be obtained from the-border it's not cheap either since you have the euro exchange but hopefully we can get them in the states soon

When they land in the states, don't forget to holla!

Good choice on plug driver Rmd, i found the same T-handle over here!

I would suggest getting a new head button. Turbo head buttons get their seal from fit between the tip of the plug and the tapered portion of the head button. Each time you remove and install a plug, if there's even the slightest amount of dirt or imperfection in the tapered tip of the plug, it scratches the sealing surface of the head button. Eventually you just get too many imperfections in the head button and they won't seal. I change head buttons about four times a season for that reason alone.

Rainier:

If you can't find a head button using normal channels, PM me as I have Sirio .12 head button still NIP.

joe check kelletts

Will do BSV

Thanks! PM Sent.

The Evo 4 has just arrived @ Kyosho America just have your LHS place the order they are also looking into getting the New Sirio clutch system as well

Is it the same price as that Italian site, like over $450?

Kelletts only has the clutch for kyosho/NT1 and are out of stock of the flyweights

Just got an update the Sirio clutch system has arrived @ Kyosho America & should be available to the public once it is updated into there system

With the Euro being a factor I think the price will be slightly higher than the Evo3 but Im not sure what the exact going price will be @ the LHS
