I'm new to this Forum & I'm also new to nitro engines. My only RC interest at the moment is boats. I bought a K & B 7.5cc in-board nitro engine for a boat. A friend of mine who knows about such engines says it has got very little compression, and that the pistons & sleeves need to be replaced.
I went to the MECOA site to look for the re-building kit containing new pistons & sleeves for the 7.5cc, but there's so much parts there I don't even know which one is suitable for what I want to do (I certainly won't be doing it - my friend will be). The model no. designatuion for this engine appears to be 9181. So, CAN ANYONE HELP HERE? (I can see 'pistons & sleeves' for the outboard, but not the in-board). Is my kit available, & if so, what part no. would be?
I REALLY appreciate any help anyone can give. Thanxx, everybody! :( [/b]
