the answer to all your questions.
yes the back trigger is the heavy triger set?. the front is the light kaboom trigger.
there are two screws yes the one in the middle of the assembly it does change the engagement point of the triger to the set trigger. that works fine. the problem apears to me that the lift on the trigger is not high enough to lift the lever holding the Fireing pin on the sear in the lock. If you take the side plate off the gun you see a bar sticking out that is moved vertical when the trigger is pulled. it goes up and the hammer falls and kaboom (in most guns but not this one.) you can pull the front trigger and it is verry hard like the rear one and it eventuly trips the hammer. I will try my hand at fixing the problem again tonight. thank you all for the help and the input on my little problem.
