How many is too many?
Wouldn't the solder kinda "wear" being soft and all?
If it were a bearing maybe.... As a travel stop cushioned by springs you might gain a degree 10 years or so down the road. But as I said "while you are dialing it in". Once you find the setting you want you can measure the lead, if it bothers you then sweat it out and weld to the dimension you measured. You can also add material to the inside rather than the outside if you want to add tension and slow down the curve or correct a unstable timing at idle situation. Sometimes the springs you have are the correct rate but just a tad too long and this will fix that.
