Only go up 5.And did you change the pilot jet up any.If it won't open up when you smack it off of idle it needs a bigger pilot jet.

You answered your own question if there is no problem when you smack it your pilot is fine. If your plug is still all white up your main jet 5 or 10 until your plug looks like is should. Worst case is you put the 190 in and foul a plug, then you know 185 is what you need.

true you can but you can't turn it that much to make a difference, that's why you need to up the main..When you all changed the jets did you move the needle down a notch too?
