Fouling plugs? Update 9/2/08

Thank MJ

I'm going to do a compression test and a decarb job using seafoam. Will report back.

Thanks

After repairing the ground cable for the starter motor, I proceeded with my plan of decarburization the motor with Seafoam. This is the second time I’ve done this since I bought the boat and once again I became amazed with the amount of white/grayish smoke it came out of that exhaust, that Seafoam stuff really works. I have a new set of Champions in and she’s running like a champ. All I need now is to find time to go fishing.

That 150 looper you have WILL foul plugs on 40:1 at low RPM's, not much you can do about it. The VRO ran them at 100:1-150:1 at idle to prevent plug fouling, but they would go to 50:1 at around 2000 RPM's and then to 40:1 above around 5000 RPM's. I would use a semi synthetic like PENNZOIL offers and mix it at 50:1. A regular dino oil at 50:1 will still foul plugs more frequently than a synthetic blend or a pure synthetic.

i used to use 100-1 amsoil synthetic blend in an old cross flow. Amsoil designed it to replace a 50-1. It worked real good, the engine idled good, but it didn't smoke enough for me, I always wondered if I had mixed the oil with the gas, or had mixed it correctly. Engine never had any issues from running it.

I’m starting a 50:1 mix ratio until I use all my Quicksilver oil, after that I’ll look into the semi or full synthetic oils. For safety purposes, I do quite a bit of idling when fishing at or near some rips (Race and the Gut) If I could cut back on some of the white smoke it would be great…

PENNZOIL vs QUIKSILVER will definately cut down on your smoking some. QUIKSILVER is a good oil, but it smoked ALOT in every engine I've run it in.

Thanks
I added gas to the tank so I stayed closer to the 50:1 mixing ratio, last Sat. I went fishing with my neighbor and his son, we burned about 20 gls of fuel drift fishing and moving around, overall, I noticed a little less smoke and no fouling occurred.

One thing I notice was the lack of top speed, the max I could do was 33 mph.(usually 42 mph) Can’t figure out why…

Prior to the trip, I installed a brand new set of Champions set at .030 gap. Did I buy bad plugs?


Thanks
