Optifuel - smokey?

[chickentikka25]

Hi all,

Just wondering if anyone else is having the same experience as I am. I recently changed to Optifuel 25% from Werks Racing 25% - basically cheaper and more in the 'gallon' bottle.

I've re-tuned, got the engine just about right, but it's pouring out a lot more smoke than the Werks stuff. Power's fine, acceleration's fine, temperature's fine - I tried glowplug firstly, then replaced all hoses to make sure there wasn't an air leak, and have replaced the air filter just as a matter of course while inspecting the intake pipe.

Tried another tankful of the Werks stuff just in case, re-tuned, nowhere near as much smoke. Went back to Optifuel, it's smokey again.

Just wondered if anyone else has used the fuel and has found the same?

Cheers.
