Thanks for all the suggestions and help!!! WOW! is all I can say – lots of knowledge here! I really want to stay with this motor and give it a fair shake – I just bought it a week ago and it is just too pretty – it looks like a museum piece with fresh paint, decals, rebuilt carb, points, water pump, etc…. It is really cool on the little boat I take camping – it gets lots of attention as nobody else at the lake will have one that is for sure. I am not in a real rush when I use it but it would be nice to plane the boat. It was a one owner fresh water motor that has been completely restored by a local fellow and is in outstanding running condition. I am now in search of a 3 blade prop I guess… anybody know what pitch the 7.5 was supposed to be and where I can find a 3 blade? Also I hear I am supposed to run 16:1 mix – seems a bit much to me with full synthetic modern 2-cycle oil I am using – is it ok with 32:1? 32:1 is what the seller advised I should do and an old marine repair guy said 50:1 with modern full synthetic is fine but that scares me a bit. The motor has been converted to a fuel pump and uses a modern plastic 3 gallon tank/hose system. I am using non-ethanol 87 octane in it and I have some SeaFoam I plan to use every so often. What else should I know so I do not mess this little gem up? Thanks for all your help!
