hello, when i broke my car in with the static break-in i did two HALF tanks accidental (did'nt read instructions) well now i have done 2 half tanks at low speeds and 2 full tanks at low speeds. i have one more full tank left to go before i can reach full speed. My question is that it has a ruff sound. I know it says it will have a ruff sound but fr how long? maybe i'm just over worrying but i did only do 2 half tanks of static break in ... will this affect my cars performance hugely? any views will be most helpful. I just hope that the ruff sound won't be there to stay [&o]

What do you mean “ruff sound”? When running?

Regardless of how many tanks or half tanks you’ve run so far, as long as you didn’t start leaning it out and tuning it, just continue the break-in procedures as noted in your instructions.

That ruff sound (think you are talking about the exhaust sound or like a no power sound) will fade as you go through the break-in steps and start to tune it.

I would think a "rough" or "blubbery" sound would indicate rich running, which is what you want during break in. The idea is to run it rich so you can get a good amount of lubricant to the internal parts of the engine during break in.

ah great thats ok then *PHEW* ... thanks alot then.
