- Pilot Jet Size
- Main Jet Size
- Type of needle
- Needle clip position
Now I'm talking numbers here, not generalities. "Up one, down two" really means nothing without a point of reference. Here's a good starting point to pass on to your bud...
Elevation 0 to 4,000 feet
30 to 45 degrees: 172 main, JD Blue #5, 48 Pilot, 2.0 turns, 75 starter jet, #0 leak jet
45 to 60 degrees: 170 main, JD Blue #4, 48 Pilot, 1.75 turns, 72 starter jet, #0 leak jet
60 to 75 degrees: 170 main, JD Blue #3 or JD Red #5, 48 Pilot, 1.5 turns, 70 starter jet, #40 leak jet
75 to 90 degrees: 168 main, JD Red #5, 48 Pilot, 1.25 turns, 68 starter jet, #50 leak jet
90 degrees plus: 165 main, JD Red #4, 45 Pilot, 2.0 turns, 65 starter jet, #60 leak jet
Also, just a little FYI, 4-strokes have fuel screws, 2-strokes have air screws, and they work opposite of one another ...SC

What brings you down to that shit hole la paz???
Pardon me? What's wrong with La Paz? Considering it's thought of as one of the top 10 places in the world for Americans to retire, you obviously have some personal issues with the place. I have 1.5 acres in a waterfront subdivision there that has tripled in value in the last 6 months, so I don't know where I went wrong. Maybe you can enlighten me .
If your buddy is running a 170 main (+2 above stock), and a 48 pilot(+1 above stock), but is still popping on decel with his fuel screw cranked out, then he likely has internal engine issues. Most likely a few tight valves, if there truly is no exhaust leak. Overheating the way it does may be indicative of a cooling system issue as well, bad water pump, bad radiator fluid, etc. Like I said before, we're gonna need those numbers to be sure...SC

Try pulling it when the engine is running and see if there is any difference. The rpm should rise and it should sound different.
If it doesn't, that's most likely the problem.
