i cant seem to find the compression stroke and i,m not sure why.i put my finger over the hole and theres very little compression.i checked the cylinder walls there in spec and the piston is also in spec. if i take the head back off and turn the crank untill its on the T line does this mean i,m on the compression stroke? i just cant seem to get this figured out and really dont wanna put nomore money in it. it had a ton of power till i changed the cam. i still dont think the rings are seating in the piston right.and i,m sure this will cause it to not build up pressure.i spaced the rings like the picture shows and i still have no power.anymore help will be apprictiated.
