Have you set the flipper bat gaps so they have some up and down play?

No. A fuse either works or doesn't work.

Check to make sure the flippers have the right gap between the bat and playfield. It should wiggle up and down a little bit. If that is ok then take apart the coil/link and check to make sure it's not all gummed up with something or super dirty.

The left flipper is actually a weaker coil than the right to start with so don't compare the two.

On my machine the left ramp is just barely backhandable from a trap. How does that compare to yours?

Based on the fact you replaced the flipper link i'm guessing you didn't leave the gap between flipper and playfield.

Some games have different strength flippers based on playfield design. sometimes a coil is too strong if all the shots available to that flipper are close to the flippers or the ramps are shallow, etc. On Tron nothing from the center to the right of the playfield needs more strength to hit. It is a scoop, an orbit, jets, or the center 3 bank, or Zuse targets. The stock coil they shipped the game with is more than adequate for the game. Mine has no problem at all making any shots with the correct speed, etc.

It'll be a weaker coil but not my much. It doesn't have a ramp to shoot up or anything. Make sure you properly gap the flipper preferably using a flipper gapping tool. The tool is critical if you're not a veteran at flipper rebuilds (and I'd argue even then). http://www.marcospecialties.com/pinball-parts/03-8194

No matter what you do, you will not be finding the ramp a regular backhand shot. Maybe on a freak perfect shot you'll do it. But its not intended to be a backhand shot. You risk more of a reject to center drain than a success. Plus the game will become harder with the extra power to the close shots. Like missing the scoop and hitting the zuse standup at high power and air balling to the drain. There are other games with mis matched flipper coils. Iron man is another.

I would like to say that I have probably rebuilt over 100 flipper sets (100 full machines). And I use the flipper gap tool exclusively. I have had people asking me how I get my flippers to feel "better than new". I don't care how good you are, you should probably have and use the tool. I've even regapped flippers on NiB machines and improved their performance. I think stern eyeballs it in their factory Vid1900 wrote a rebuild guide on pinside and he even recommends the flipper gap tool.

Also, when you do a flipper rebuild, replace that nylon bushing between the flipper bracket and the playfield. That often is the cause of weak or loose flippers. You may not notice the difference until you replace it. It never comes with the rebuild kits but it sure makes a difference. http://www.pinballlife.com/index.php?p=product&id=271

Three reasons imo:

1. The ramp isnt intended to be an easy backhand like say ST. I can backhand mine like, BARELY, and it's really only 50-60% successful (and dangerous on reject).

2. No other ramp anywhere for it to shoot (orbits and targets dont need power)

3. The shots the left flipper hits are forehand shots close to the flipper (S and E targets, scoop, pop bumpers) and a bit less power doesnt break things as easy
