hey,

Just came back from a run-in of my Mach 21 engine..Got a query to ask:

Noticed that after a tank of nitro, realised that my engine will often emit a loud pitch sound, sounds like a high idling sound, it's tends to goes back to normal idling sounds a few seconds after a complete stop of the buggy..

Is this normal? if not what could be the problem.

Pls advise and thanks in advance.

regards.

my novarossi P5X does this....i havent had any problems with the engine, and i have over 2 gallons of 30% through it...

In this case, it should be normal then.. thanks Jason.

Change to a OS P3 plug will have to retune i say.
Never have that problem with myn.

hey MadRacer, I'm using OS P6 (Hot).

1. Can P3 fit into this turbo engine? ie is this P3 plug a turbo glow plug?

2. Btw, u hv experience this similar problem with P6 plug?

3. Will this do harm to the engine if i continue to use the P6 plug?

4. Do u know what is the cause of this problem, any reasons or explainations?

Pls advise. thanks.

Cant explain why it does it but i have had no issue like that useing a p3 plug.
Yes its Turbo or it wouldnt fit in mine either.
The P3 is a hotter plug and comes standard with the OS V SPEC. It is a very popular plug in off road. Being hotter it has better idle characteristics .Unfortunately mine has died . Good luck.

Thanks. Will get the P3 glow to try it out.
