Hi I have an OS Max 25 that I purchased in 1995 and i have some problems lately with it. One thing is that it kicks really hard and I have broken 6 plastic spinners at the pins trying to start it. I had a heck of time getting it run and then I reset the low speed needle and high speed needle and I got it to run. I had an issue with my fuel tank that was flooding the engine and I solved that issue and was able to get it run in my airplane. My fuel is omega 10% nitro and I have ran this fuel in it for years. I thought that I had a bearing issue but it turns out it was a couple of lose backplates screws. Can you give me any suggestions of what is going on with this engine
Thank You

Anybody out there in cyber land Know if the paper gaskets for the FX 25 will fit the SF engine. I would just like to have a set around I check my current ones and they are ok thanks Michael
