Hi guys
I am having trouble with a top mount starter on a vc mustang I found whilst down the coast on the weekend. I have rewound the spring and it has good recoil but for some reason it won't grip on the starter bucket. I have read the manual and made sure it is back together right however I must be doing something stupid. I have had a lot of luck with the power torque starters and side mount starters however this one has me stumped.

Help would be appreciated as it's making me feel silly!
