About to buy a 80 hp rotax , runs good but has 700 hrs.New in2004 hopefully some of you that fly these engines will share your thoughts with me,as to what you think the value is, and assuming it's a good engine and I treat it right when will I need to worry about a overhaul.I know nothing about Rotax 4 strokes other than they have a good rep. And Kolbers seem to love both the 100 & 80 hp versions. Any thoughts and info. will be well used and much appreciated. Thanks Frank firestar 2 HKS ________________________________ Message 2 _____________________________________ Time: 07:31:35 AM PST US From: "John Hauck" Subject: RE: Kolb-List: time on 80 hp Rotax hopefully some of you that fly these engines will share your thoughts with me,as to what you think the value is, and assuming it's a good engine and I treat it right when will I need to worry about a overhaul. . Thanks Frank firestar 2 HKS Frank G/Gang: Give Ronnie Smith at South Mississippi Light Aircraft a call. He should be able to answer your questions. I have no idea about what its value is, so can't help you there. When to overhaul? When it gets tired or tells you it has a problem. I'd do a compression check initially, so I have a base line. Tachometer will also tell you if the engine is getting tired. However, I don't think you will have to worry about overhaul. Items that wear out soonest are carb parts and spark plug connectors. I have had an 80 HP and a 100 HP Rotax prior to the 912ULS (456.5 hours) I now have. Both had between 1200 and 1300 hours on them when sold. Neither had any problems and ran just as strong when sold as when new. 912 series engines are low maintenance. Change the oil and filter, spark plugs, and clean the air filters. Check or change fuel filter. Check float bowls once a month for any accumulated moisture. No tinkering with carb adjustment except adjusting the fuel needles a notch up or down in really cold weather if required. No experimentation with jetting or spark plug heat ranges. It is nice to know the 912 is going to perform well every time the airplane is pushed out of the hanger. In 1994 I replace the 582 in my MKIII with a 912UL. That engine completely changed the character/feel of my airplane. john h mkIII Titus, Alabama ________________________________ Message 3 _____________________________________ Time: 08:22:59 AM PST US From: frank goodnight Subject: Re: Kolb-List: time on 80 hp Rotax HI John Thanks for your thoughts. It's a bunch colder here in north Arkansas than it was in Brownsville ,TX. I Fly quite a bit more because my hanger is only 12 min from my house -- it was hour and 10 min in south Texas. Stay warm and dry and Merry Xmas.

Jack B. Hart FF004 Jack H/Kolbers: 1200 hours was a mid-time engine for the "recommended" TBO. Figured we could get the best price for them. I have to thank Bruce Chesnut, owner of The New Kolb Aircraft Company, for both my 912ULS engines. It was Bruce's way of expressing his appreciation for the exposure I have given Kolb since 1984. If I had not gotten support from Kolb, I would probably still be flying the original 912 I bought in 1993. Back in the old days when I was preparing for my first flight to Alaska, I seized the 582 on my MKIII shortly after returning from Oshkosh 1993. Homer Kolb, and everyone else close me, expressed I should get a 912 (there was no 912UL and 912ULS back then) to make the Alaska flight. However, no one was offering to help me buy one. I was broke from rebuilding the MKIII that I had destroyed during testing the previous year. I rebuilt the 582, got a credit card, which I called my 912 card, traded the 582 to Ronnie Smith, South Mississippi Light Aircraft, for a 912. Ronnie gave me a good trade in for the 582. The balance was charged to the 912 credit card and eventually paid off. With the help of these folks plus many, many Kolb people, and others, I was able to make that 17,400 miles flight. I will be forever appreciative of these people who gave so generously to make that flight possible. BTW: No one has ever bettered that record made more than 17 years ago: 17,400 miles in 41 days, 232.0 flight hours, two sets of spark plugs, and two oil changes. This flight demonstrated the Kolb MKIII was not just another ultralight, and the 912 was not just another ultralight engine. john h mkIII Titus, Alabama ________________________________ Message 6 _____________________________________ Time: 01:15:27 PM PST US Subject: Kolb-List: MK3x wings leading edge From: "Rick Lewis" My intentions this summer was to cover my wings but everything else got in the way so nothing happened. Now it's cold weather and I will be bringing my uncovered wings back home to work on. That's really pittiful if you stop and think about it. It took me only 3 weeks to build them and now it's been over a years since I've touched them. [Embarassed] I have had two mechanics ask me if I was planning on sheeting the leading edge of the wings several inches back, before covering. I told them no but it has gotten me to thinking about this. I can see some reasons for this but what do you guy's think. It would be easy enough to do and would add very little weight. This would also make and easy bonding area for the cloth. -------- Rick Lewis (VW Watercooled Engine) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=361420#361420 ________________________________ Message 7 _____________________________________ Time: 02:32:29 PM PST US From: "John Hauck" Subject: RE: Kolb-List: MK3x wings leading edge I have had two mechanics ask me if I was planning on sheeting the leading edge of the wings several inches back Rick Lewis Rick L/Kolbers: Based on observation of others that have, it will not improve performance. I don't know if it will degrade the wing's capabilities or not. I have never used a sheet metal leading edge on a Kolb. Homer did a good job designing the wing. I fly it like Homer intended. john h mkIII Titus, Alabama ________________________________ Message 8 _____________________________________ Time: 05:27:13 PM PST US Subject: Kolb-List: Short Short field take off and Landing From: "David d."

Should have a perfect fit. However I do remember a thread from a few years ago when that was discussed and the consensus was to not do it as it would contribute nothing!!! So I don't know which way to go on this topic. ======================= ---- Rick Lewis wrote: ============ My intentions this summer was to cover my wings but everything else got in the way so nothing happened.
