Hi has anyone set up one of these engines the one i have seems to be pumping a hell of a lot of residue out the exhaust, it is basicly set to the manafacturers spec. any help would be great.
Never had the pleasure of a 90 , but like other OS engines it will probably be set to 3 turns out to break it in, which means loads of fuel, how long it needs broke in for is up to you, i dont think it needs more than 2-3 tanks at 3 turns before i start leaning it in.
