Carb adjustment question

[tex599]

I have a 1992 Johnson 60hp, j60tlene. When setting the mixture screws (on the top left hand of each carb, when facing the engine) I read to set them at 1 1/2 turns out. It seemed that were much further out to begin with, 2 1/2 to 3 1/2. So I adjusted them all to 1 1/2 and fired it up on with the muffs on. Runs fine, but still seems rough. I know these motors are not going to run as smooth as a v-8, mine bounces around some. The idle is about 1K on muffs, not sure about on the water yet. But what am I looking for as far as a tuned 2 cycle motor should sound like? Reason I did this is the plugs were getting fouled with oil on the inital startup from cold, once pulled and dried motor would fire up fine and run good, smoke alot. Seemed to be it was running rich. How do I know if it is running to lean or too rich?
Thanks,
SW

Re: Carb adjustment question

Go to TDs "top secret file" near the top of the index and find the item on adjusting carbs.

Ok The carbs you have are different to the ones described and I believe the initial settings are different** but the procedure for adjusting is basically the same. (Maybe open the settings a bit to start with)

**But I forget what they are!
Maybe someone will come along and tell us the "correct" setting but its only a starting point.

Re: Carb adjustment question

Thanks for your response. Looking at the sticky it says the directions are for older engines, being a 92 model this might be considered an older motor. Couple of other questions: since it is a 3 cylinder, I start the adjustment on the middle carb correct? What sound am I looking for to know whether it is properly tuned?
thanks

Re: Carb adjustment question

TD's Top secret file is the first item in the index to this board.

AFAIK all the links are to items that appear in the Engine FAQs board so you can also find them, and a few more other useful items as well, by going to the FAQs board .. the first item in the "Repair and Maintenance" index
