I have a irvine tutor 40 with a 40 os engine need a bit of help please??????
You leaned it out if you turned the "screw",needle valve in .If it did'nt run for to long,you are probally okay.Make sure that your engine is blowing "smoke" out the exhust as this is what keeps them cool.And seek help at the field and I am sure you will find it.Good luck!!
