Hi, I have a go 5 port .21 non turbo and I notice a oily residue all over my crankcase which I think may be fuel? can this leak from the carb? I have heard of air leaks but not fuel. Can anyone let me know if this sounds likely because I'm a bit new to this
If it may be a fuel leak I will check the seals and seal with RTV sealer
Thanks,
James
