Hello all and Cheese! I've learned to fix almost any small engine mainly by asking questions here. I've been doing it about 2 years now. I've run across a problem that I haven't faced before so I hope you can help again. I have an IDC 520 supreme Model 520-2 String Trimmer on the bench. I was going to tear it down for parts (I've never even heard of IDC before being given 2 of them) however, I found good spark and great compression. The carb is in excellent condition! I must remove the clutch to be able to remove the cowling. I've never removed a clutch that is designed this way. I've seen a lot but never needed to remove one. It has a long nose that the trimmer's drive slides into. At the bottom of this part of the clutch is a fastner? I've tried torex, hex and a flat head. [COLOR=DarkRed]What do I need to use?[/COLOR] It looks like a flat head should do it but I can't get one into the opening that is wide enough to span the fastner. I had to grind an old flathead just to get it to fit? None of my other tools will fit down the throat? [COLOR=Red][B]Is there a special tool?[/B][/COLOR] As always, my thanks, Ron!

I have a Troy Built Pony rototiller with a 5hp Briggs & Stratton it will start every time but will only run for about 25 to 30 seconds. Where is a good place to start? :wall:
