Is it elec./mech.? I own one of each and I would say YES for sure.
Now for the timing and set up... This is the reason that you can pick up the Draguns so cheap. Most people are not able to do it correctly. The owner of my field id GREAT with the Draguns. He changes out the springs, opens up the valve, and times them perfectly. If you are unsure of what you are doing it may be worth the shipping to have it done right. However there are threads here with how to time them if you want to try it.
Best of luck...enjoy your new Dragun and all the money you just saved!
