I haven't really had any trouble with the repro switches in the last 10 years or so.Couple of things that I have found out though.If you use a firewall insulator your shoe might bottom out before it makes good contact.I stretched out my starter rod,made a world of difference.The biggest thing I found was soft shoes can be a problem.That little pad pushes right up into soft shoe soles.The shoes made for people with foot problems,and issued by the VA are the worst.I have a pair of walking shoes that I have to work hard to push the starter button.Hard soled shoes just need a light push to do the job.
