Installed Kent fast road cam(Duration 276deg)

[JapS]

Hi everyone
My Japanese S3c engine started at last.
But engine will not rev up and that felling is so bad.
I checked plug which prove gas is lean.
I installed Kent fast road cam(duration276deg).
If anyone use this cam, please let me know how to tune engine feeing.
And do I need replase engine management system like full conputer like motec?

Thank you

That's not a particularly aggressive cam, so you shouldn't need any specialist management. How did you time it? Sounds like the cam timing is out.

As said above, something is seriously wrong????

I fitted a Piper 270 (not so different), engine ran a treat with no re-tuning

I agree, changing to a fast road cam shouldn't make any major difference to the running when not under load. Either the cam is a notch out or something else has been disturbed. Check the cam position VERY carefully and without revving the engine any more.
Let us all know what you find.
