I don't see why not. As long as everything is adjusted properly and the shot still won't clear the ramp, you wouldn't be out much but the cost of a coil and some time.

That shot is notoriously borderline as to whether or not the ball can make it up the ramp. You have to hit it just perfect, but if you don't it typically gets rejected.

Check the ramp that leads from the flipper to the couch. On mine, the two small screws that hold the ramp flap to the mini pf were so tight it pulled the ramp down, so the ramp and flap were not a smooth, even surface for the ball to roll on. I loosened them until they just hold the flap and ramp in place and the path for the ball is smoother. Also look at the posts near the ramp flap and use smaller post sleeves for more clearance. Check the stainless steel wall guide on the right side of the ramp to be sure is smoothly guides the ball into the ramp curve.

Also, make sure the ball gate going to the upper couch is free and not hitting any wires when the ball passes through it. It is tight up there, and I have seen that gate reject shots.

One last thing, I pitch my games really steep and I can make that shot without issue- if you wait until the very end and shoot basically from the tip of the flipper. The two upper flippers on this game have very unique shot timings/sweet spots.

Probably close to 8 or 9 to be honest....

I have had 8 TSPPs over the years... All similar in behavior, those right flippers are unique.

One other thing to check... Those long plastic tubes under the mini flippers wear out over time... Is your clearance from the flipper still good above the mini playfield?

It's not the playfield angle... Steeper pitched games need more flipper strength. I was using that as a reference that even with a steeper pitch, I don't experience issues.

Try practicing waiting until the ball is almost off the flipper and then shooting. Sounds like a timing issue more than anything.

Just out of curiosity... Take the little gate out (pretty easy to push inwards and get it to come out) and see if your results are similar. If you find it is a lot cleaner, the gate may be robbing momentum. You can adjust the bend on the gate switch to lessen the force a bit and still register.

Forgot to mention to wax the heck out of the mini pf and the ramp and flap. Make sure the flipper rubber is in good shape and clean.

I believe it is critical for the four way combo, but am not 100%. I think the machine looks for that with a subsequent trigger of a ball landing in a couch to denote a successful make.

I was buying them in bulk from Chuck E. Cheese. I was buying those and Pirates and working with a seller with a direct line to Chuck E Cheese warehouse.

I wanted a good deal on one for myself, and was paying it forward on the rest, but I had to buy all of them to make it happen.

This is great advice too. Keep it as slick as possible.

If you still have issues, you can buy some weatherstrip foam and cut it down to size and put it under the flap, just behind the entrance flap, but still in the playfield recess. This will make the transition very smooth, and most likely take care of it.

Williams did this by default on a lot of their machines.
