plugs look too "wet"
"Larry" wrote in message ... "Chuck" wrote in news:5TSck.244293$yE1.55866@attbi_s21: What should I look at adjusting? NOTHING! That's LUBE OIL coming up from the 2-stroke crankcase to keep the bearings lubed up! Why screw around with something that's running great with good lubrication?! Why does everyone have to tear apart perfectly good working things and screw it all up?! If it's a 4-stroke, you have bad rings or valve seats.....my condolences. A proper 2-stroke should be all gooey right to the end of the exhaust outlet. If it's not, dismantle the damned autoinjection used to wear out new motors fast so they can sell you more and premix the gas to 25:1 with OIL COMPANY BRAND NAME TC-W3, not the cheap crap from engine manufacturers the dealer sells! Engine manufacturers don't have oil refineries. Who knows who made it....lowest bidder?? When I sold a 150hp 6-cyl Merc Sport Jet with 3 deuces carbs on it, having run its whole life on 25:1, you could still see the hone marks on the cylinder walls and every bearing in the crankcase was as tight as new.... (c;...hundreds of hours later after running wide open all that time. 100:1 is SUICIDE! BTW - AMSOIL IS NOT AN OIL COMPANY! The only reason I checked the plugs is because the responsiveness felt a bit sluggish on the night of the 4th. It didn't have the normal top-end like it did last season. At least I feel comfortable that the plugs are supposed to look that way now "all gooey." Thanks |

I running with a 130 degree thermostat. What should I look at adjusting? Chuck Before I got crazy and tried to "fix" a motor that was running well I would ask, how far did you have to idle back to the ramp before you pulled these plugs? If this is running well other the entire range I might try a little hotter plug, if it is loading up when you idle you could play with the idle screws a little but be careful you don't break it. I see your point about the idling...... it took me at least 10 minutes running at idle rpm. I never thought of that. BTW, this is an automatic oil injection system and so I cant adjust the fuel/oil mixture ratio. To check the plugs you need to run at a cruising speed and then shutdown, pull the plugs and take a look at them. Idling around for anytime is going to load them up on a 2 stroke. |

But before I do, I am curious to know if anyone ever bothers to clean em, and if so, with what, or do you always replace? I had always just replaced them. My thinking is compared to an engine rebuild or replacement, the investment is worth it in my mind. The engine in question in this case is a 2004 Yamaha 300 HPDI. |

The plugs is the family ride looked fine at 100 000 miles, but we replaced them anyway. Platinum points of course. Two hours labor to change the plugs. Casady |

Chuck Doesn't anybody want to know what the problem turned out to be? scroll down................ down more.............................. Remember its a 60hp motor on a 24ft pontoon party boat. On the fourth of July I had 14 people on it and THAT was the reason it felt so sluggish and caused me to check the plugs, which is when I noticed they were "wet." When I have a few people on the boat it cruises easily at twenty knots. Yeah.... don't anybody say it......... go ahead.......... |
