Anyway, I purchased a 5 rib Firestar restoration project a couple year s ago and thought I would repower it from a 447 to a 503. While I had it str ipped down to the frame, I took it by the new Kolb factory for some updates a nd asked the question about the 503 exchange. Their recommendation-don't do i t. Having the extra power load on the frame is very stressful. The steel tub e that the engine mounts to had a wall thickness thin enough to help with ho lding down weight to stay 103. When at full power in a climb, all of a sudde n you fly into a thermal and really bump the strain on the mounting tube whi ch could fold up. That's the explanation Dennis at Kolb gave me and after he aring that-made sense. I'm staying with the 447 but I have other issues with that engine I'm trying to figure out. The pull starter does not pull thru a s it should. Feels like it has way to much compression and just bumps from s ! >> tr >>> o! >>>> ke to stroke not able to spin it up.

I have had a lot of fun with the Kolbra the last 10 months, did a lot of minor repairs, radio work, & rigging changes. I've put about 50 hrs on her in that time & I have sold her to a fellow in Virginia. He should be picking her up within the next few weeks & I will introduce him to the Kolb List once he gets her home. The 912UL 80 hp has plenty of power and has been an unbelievable performance difference compared to my old Firestar with the HKS. However, the Kolbra is not nearly as nimble as the Firestar was and requires a much wider turning radius. I have enjoyed the 2 Kolbs I've owned and I have no doubt I'll own another one some day. www.youtube.com/watch?v=tVx9ppASfm4&feature=youtu.be Enjoy, Jimmy Y Houston TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=430865#430865 ________________________________ Message 3 _____________________________________ Time: 06:03:30 AM PST US Subject: Kolb-List: Re: 5 rib firestar From: "Thumper" Well do you have a prop on it? I once had a Hirth F33 single cylinder that no one could pull through, no one. With plug removed it pulled fine. Called Rec Power and he asked me that same question, we thought he was nuts. But we installed the prop and it pulled through just fine and started right up. Ran great till I sold it. Guess the prop weight acts like a flywheel and helps with overcoming the next compression stroke. Try reattaching the prop and see what happens? Just an idea.

I neglected to re-install my HACman system from Green Sky. I also left off the tubes from the chamber vent ports. This of course force fed the carbs. I flew to the top of the Steen's Mtn, or rather attempted to. https://vimeo.com/104478744 password- Owyheeflyer The engine was running rough, EGT's Dropped to 940 or less, could not maintain rpm's and finally had to drop off the Mtn at 9600 feet. My RPM's Dropped to 5400 at that altitude with full throttle. I re-installed the HACman from Jerry and finally got the time to fly. It was pretty overcast with smoke from the California fires. I had a bit of trouble with my camera having enough light to give a clear picture. My best climb speed is 50 MPH, and I averaged 500 FPM to 10,100 feet MSL That is a climb of 6100 feet. It took me 23 minutes to climb. The HACman allowed me to maintain 1230 EGT, engine rpm's remained at 5750 RPM's. Engine CHT was 315 degrees. At 10100, I cut the engine and did a dead stick landing. It took me 10 minutes to touch down at a descent speed of 40 MPH. I also checked my stall speed at 10,000 feet and it was 29 MPH. The engine never seemed to bog down and ran just like it should. I can't say enough about Jerry @Green sky Adventures for the help he has given me. Of course my little Kolb Firestar II completes the picture. After landing I restarted the engine and after it warmed up, took off again and flew around the area for a bit for a total flight time of 54 minutes. I burned 1.75 gallons of fuel for the entire flight. https://vimeo.com/106739407 password - owyheeflyer Larry -- *If you forward this email, or any part of it, please remove my email address before sending.* ________________________________ Message 6 _____________________________________ Time: 12:08:16 PM PST US From: "George T.
