Reference `cooler`. just got back from Portugal. 3 days in Lisbon, a very nice city and then a week up the Duoro from Oporto.Temperatures around 104 for 3 days. Not a wide river. In some places not much wider than the boat. Several massive dams. A couple were around 200feet high. Steep sided valley covered in vines. The port wine growing is strictly controlled and only extend s a little way up the valley. After that it is just Portuguese wine which is OK but I didn`t buy any. In fact I find that I buy mainly Australian or New Zealand or Chilean or Spanish. Nice wine at a reasonable price. No one seems interested in buying my Kolb. Bugger!

Ill be watching for your posts. Chris Thanks, Chris/Kolbers. Looks like I have my work cut out for me today. Winds are forecast for "breezy conditions out of the south from here in Laramie, WY, to Neosho, MO. I would like to make Neosho, but the winds will be the determining factor if I do or not. I have a good place to stay in the FBO at Goodland, KS, if the wind proves to strong to be comfortable and/or economical. john h mkIII Laramie, WY ________________________________ Message 3 _____________________________________ Time: 06:46:13 AM PST US Subject: Re: Kolb-List: prop From: Richard Girard Frank, Does it have the plate and plastic blade blocks or the CNC machined one?

Mine is a bit cleaner, and with a two blade warp I am doing about 67 at 5500 as much as 75 at full cruise of 5800. Climb is perhaps 450 fps at 4000 feet. I did put Jimmy in touch with the guy and he got them, but he has since sold his Firestar.

The WD is a three blade, the Powerfin a four with "F" blades. I ran the WD on a 582 with a 4 to 1 gearbox and the Powerfin on an HKS with the 3.54 to 1 ratio. I thought the two engines and their gearbox ratios were close enough that they would interchange so I tried them both on the 582 on my Mk III. When I put the Powerfin on the 582 would not rev past about 4200 rpm and I aborted the take off. The HKS from which the Powerfin had come would rev to 6000 in climb and 6200. By the time I repitched the Pfin to work on the 582 I lost almost ten miles per hour. I pulled two blades from the prop and repitched it for the 582 and got back 6 miles an hour. My conclusion was that the HKS has a much broader power band and the Powerfins ability to absorb it made it well suited to the engine when run with that gearbox. How well it would work with the lower ratio gearbox I do not know. On the down side, on two occasions I have learned of the fragility of the Powerfin. The first was when I forgot to put my glasses on and left them hanging from the collar of my tee shirt. The wind ripped my glasses off and they went through the prop. That cost me for two blades. A cheap pair of five buck Dollar General bifocals cost me $330 that day. The second was when I let the prairie grass get a little long in my back yard and I taxied my trike out without mowing first. Tore up the ends of all four blades and I had to go from a 68" prop to a 67 1/2" to get it cleaned up and balanced. Obviously, the second would not have happened on the Kolb, but a bolt or pin would do at least as good a job on Powerfin blades as those cheap glasses did.

The prop in question has a nick in it that has been repaired with JB weld. Not sure what caused it, rock I suppose. My two blade warp launched a pair of heavy duty dikes all the way to the roof of my hanger and down through my wing and I couldn't find a nick in either of the blades. Just thinking about faster and smoother. Probably better off where I am. Thanks Larry On Tue, Jul 3, 2012 at 9:16 PM, Richard Girard wrote: > Larry, I have both WD and a Powerfin.

The Rotax installation manual, page 15-1 shows the single outlet fuel pump (Mikuni DF44) used with the single carb engines. On page 15-2 it speaks of using an electric and pneumatic pump with a max pressure of 7 psi. Mikuni only lists the pump output and the DF52 at 35 liters per hour is over three times what the DF44 puts out.
