Default D21B First start

I just bought a D21B for my hyper pro.
What I am wondering is if the starter box will spin the engine since it is so tight. I have a 12V big motor starter box which i bought with my Hyper PBS and have been using it for both buggies.

Will it spin the STS engine?

Loosen the plug about 1/2 turn may help. When the engine start screw it soon.

Fired up on my hyper starter box and all went well.

Hello every one, but this question is for Dino.tw

Here in my club, there is many people interested in D21B engine, and they need some information to buy about 5 o 6 motors for so many guys.
Are down power of this engine like Novarossi P5 o Sirio Kanay EVO 2 more or less?
What about high power?
In South of Spain (Granada), temp. are about 20 to 45, are the os#8 a good plug for this temp.?
What shims must to use with 25% of fuel?

Best regards from Granada (Spain).

Dear Sir,

Sorry,I don't comment on other manufactories's products. I have no idea about P5 or Sirio. STS wish to produce the best MIT engines. From our product you can find our hard working. Please try one and you will see its different.

The weather is almost the same with Taiwan. OS plug is short body. But our engine fit with long body plug. If you want to us OS standard plug on D21B,remove the brass shim of the plug. Otherwise you will get low compression. About head shims,try 0.4mm(total) for 25% first.

Regards,
Dino

I'm somewhat confused
you say there are so many shimms in the D21b but in the manual it's stated not to use standard more then 16% fuel with standard set-up shimms?????!!

the complete instruction manual from the net =

" before you install the button head, do not forget to install the proper number of compression gaskets. We suggest you use at least 0.3 to avoid hitting....

ok, I see, you should not place some shimms but take them out then, is it that ?....

it says:
0.3 : under 16%
0.4 under 20%
0.5 : under 25%
0.6 : under 30% nitro

but also use 10% oil in fuel
most fuel have only 8% or so ?????????????

From page 1 - stock shims: 0.1mm(brass) + 0.2mm(brass) + 0.3mm(aluminum)

So yes you need to remove if nitro 25% or less - I am running .2 with 15% nitro.

My fuel I have been running has 15% oil, 10% syn and 5% castor. Guess it depends how long you want engine to last Vs Performance

(My next bottle is 18% , have to see how it goes... )
