Hi Bax,
How are you doing? I just wanted to know that will a Four Stroke Engine run , with wrong timing set on it.

Sharad,

If the camshaft in an O.S. Max four-stroke engine is installed incorrectly, we'd not expect the engine to run very well at all, if it will run. Even one tooth off will affect the timing drastically.

Dear Bax,
Thank s for answering. If you remember I had asked you about a 70 II FS OS MAX which I opened and lost the timing . No when I have fixed it back keeping the timing at 6 O' clock the engine is running .

Is this timing position right.

Let me know

Sharad

Sharad,

On O.S. Max 4-stroke engines, the timing mark is NOT at 6:00 o'clock. It should be set so that it's aligned with the center of the pushrod tubes/cam follower when the engine is at Top Dead Center. If it's aligned at 6:00 o'clock, you'll be 1 or 2 teeth off.

Dear Bax,
Thanks once agian for you reply. In this case the engine timing set wrong by one or two teeth off from the setting , what kind of response will the engine give.

Secondly, Now how should I align it with the center of the push rod.

Thanks & Regards

Sharad

The proper way to set the timing is in the following FAQ:
