Ok, I got the rebuild done on all 3 flippers on High Speed. I played first game and wow, flippers were strong and snappy, but after 15-20 min. the left flipper got real weak and barely hit the ball mid field. I pulled the glass and lifted up the playfield and felt the left coil a lot warmer then the right one and both coils are loose in the bracket. I tried squeezing my hardest but it wont sit tight. Not sure what to do, as I don't think the loose coils are the problem as I mentioned the right and upper flipper are excellent in strength. Upper flipper coil is tight in bracket, all coil brackets seem square. Thinking of c-clamping both ends while I tighten the hex bolts on the coil stop. This has beemn a frustrating adventure. I only done one other rebuild on this machine 4 years ago and did it in 30 min. and had no issues. I'am now maybe 15 hours total trying to get this setup to work. Also the right flipper has about 1 1/2 play up and down movement and the left one has about 1/8-1/4 of a inch of play up and down, upper flipper has about an 1/8th of a inch also, but like I mentioned the right and upper flipper are performing strong its the left one giving me all sorts of problems. I assembled all three flippers the same way, so not understanding why all 3 have different play. What am I doing wrong here? Yes I did make a gap tool out of an old credit card, yes I inserted it between the flipper and flipper bushing, I pushed the bat down on top of the gap tool and tightened the pawl a little and then aligned the flippers, and tighten down to hold flipper in place. This just has not gone as easy as my first rebuild. I also had difficulty in putting in those small return springs in those holes and kinda stretch the springs some getting it in the holes. Still have the snappyness and the spring snaps the flipper back to the resting spot, but there has to be a better way to install these springs, yes I used needle pliers and they stretched the damn spring at the ends. On this rebuild the I had to use system 11 coil stops ( good thing I ordered them) as the ones that come with the kit did not fit and are longer then the system 11's, also had to use the old hex bolts for the coil stops as the new ones did not want to go in. Sorry for the long post, I just trying to give you an idea on what I did, and whats going on to see where my problem is. Vid1900 you mention using a rat tail file to elongate the holes so the coil tightens in the bracket, what holes are you referring too and what is a rat tail file? Thanks.
