Hi All,

My kt735 appears to have "lost" its compression release. It will spin up fine on the first attempt to start. If it does not start on this first attempt, its a pain to get it going. For some reason, it becomes difficult to turn the crank. The battery is fresh. If I attempt to jump from the starter or from a different battery, the same thing, no crank. If I spin the crank by hand, just a bit, sometimes i'm lucky and it will crank over. After resetting the valves to perfect, I have come to the conclusion my ACR is faulty. I am told there is an access port to view the cam. If your lucky you can sometimes get the spring to reattach to the ACR weights on the camshaft. Does anyone know where this access port is? Have you done this before ?

Cheers
Vern

You should be able to remove the valve cover and rotate the crank and watch for the decompressor to slightly open the valve in between the normal opening and closing to verify if its working.
