John Deere j3816 problems...

Picked up a John deere j3816 chain saw. I know it's definately
not the top of the line saw, and it is what it is. The saw was
used very little and is in excellent cond. The saw has ben
setting in it's case for a number of years with no fuel in the
tank. With fresh fuel and a little Sea Foam a new plug the saw
fired up however dosent seem to run as it should. Trying to
adjust the carb. Could some one explain the correct direction to
turn the Low and High jets to get the saw to run as it
should....

I would rebuild the carb first. Then worry about the
adjustments. The diaphragms in the carb are probably dried out
and fatigued. Just my .02. Turn the screws in to lean out the
mixture and turn the screws out to richen the mixture. Can be
more help if you tell us how it is running. Hesitation of idle.
Won't idle, etc. Would start with 1 turn out on both screws for
a lightly seated postion.

Thanks for the quick reply. The saw runs decent as it is, idles
good, accelerates good. Notice that there is very limited
adjustment on the L and H screws on the carb. The only problem
is that it is hard to start. And the chain oiler put's entirely
to much oil on the chain, assuming there is no adjustment for
this.........Thanks again.

Not familiar with that particular saw. But would have to think
there are limiter caps on the H and L speed screws.

Looking at this John Deere IPL

appears to show the plastic type stops sticking out to limit
movement. Trim them down.
