Help B&S 17.5 Intek

Hi, need help.

I have a Ariens ride on with a 17.5 BS Intek (Model 31G777) which will not start. It turns over slowly and struggles on the compression stroke (often stalling completely). I have reset the valve clearance as per spec (.003-5 intake. .005-7 exhaust) 1/4" before TDC.No joy. On removal of spark plug engine turns fine so I am assuming it is not the starter motor. Even jumping from a fresh power source does not help,

How can I check to see if the compression relief system is working properly as I think this is at the root of the problem?

Any help/advise appreciated. Prior to this the engine was running fine.
