If so is there more when you burn 100LL? Thanks, > -------- > Scott Scott: Yes, when running a steady diet of 100LL there will be a good bit of led in the bottom of the tank. One of the primary reasons I flush it with gasoline. I take it apart about every other oil change and wipe it down after flushing with gas. During the flying season, especially during long XC flights out West, those oil changes come around quickly. I don't remember what the book dictates for intervals, used to be 100 hours for auto fuel and 50 for 100LL, but I change mine about every 25 to 50 hours depending on where I am and how convenient it will be to do the oil change. I've been running some semi-synthetic Shell Rotella T, 5W40. Couldn't find any, so mixed up a batch of dino and syn 50/50. The next oil change and the rest of next year I am going to run straight Rotella full syn to see if it is suspending lead as good as the semi-syn oil. That is the primary reason for running dino oil when operating on a steady diet of 100LL. However, if one goes to the spec sheet on Rotella full syn, it is based on fine dino oil, if I read the spec sheet correctly. I should be able to tell after the flight to MV and Oregon next May. I'll end up with about 75 engine hours on steady 100LL with a couple cans of auto fuel thrown in occassionally. john h mkIII ________________________________ Message 2 _____________________________________ Time: 05:53:00 AM PST US Subject: Re: Kolb-List: 912 Carb Heat From: zeprep251@aol.com Being in Ohio gives me lots of carb icing weather.Never had the bing 64 ice completely but it got rough running at cruise rpm.

When the blade is in position and the pitch is correct, the reflected beam hits the same spot. Works just as well, little mirrors are still cheaper to buy than lasers, and no fixturing is required.

This can be caused by wind or any touching of the airplane during and between blade adjustments. Also any variation in blade position and placement of the laser on the blade. I used to aim the laser at my flaps to eliminate the plane movement issue. I thought that this was more accurate than the factory method but the prop runs smoother now using the factory method. Powerfin has a indexing hole which is drilled in the blade root at the factory for a dowel pin that we use to measure clearance in a adjustment window. A .020 change with feeler gages equates to 1 degree pitch change.
