Chainsaw Repair

Looking around in my barn I had a complete Stihl FS-45 curved shaft trimmer standing against the back wall of the barn. It was originally a shabby Ebay FS55R straight shaft trimmer that I had bought for parts and I used the FS55R shaft and cutter head parts from it on my FS45. So I had put the 45 curved shaft parts on the Ebay trimmer.

Thinking about that trimmer power head today, I had enough FS55R parts to make it a FS55R again. To my surprise, the trimmer started right up. But it doesn't idle right. I figure it was someone's frankentrimmer and they don't have the throttle cable and other throttle mechanism routed correctly? I'm out of time today but some other day, I'll take that area apart enough to look for problems? If that doesn't get the trigger working freely and solve the idle problem, I'm looking for a air leak. The starter cover is all busted up but it stihl functions to start the trimmer. I'll have to get a bare cover and transfer the starting mechanism over to it. The spark arrestor spud is missing from the muffler but does not make the trimmer too loud. The off-white cover is dirty but I'll get it cleaned up some after I get the other problems fixed. Now I need a Stihl FS55R name plate to go on the starter and it will be complete.

Some of Brazil's finest . . .
