    Hello 5 rib- This is a little late but I've not been on the site for a while. Anyway, I purchased a 5 rib Firestar restoration project a couple years ago and thought I would repower it from a 447 to a 503. While I had it stripped down to the frame, I took it by the new Kolb factory for some updates and asked the question about the 503 exchange. Their recommendation-don't do it. Having the extra power load on the frame is very stressful. The steel tube that the engine mounts to had a wall thickness thin enough to help with holding down weight to stay 103. When at full power in a climb, all of a sudden you fly into a thermal and really bump the strain on the mounting tube which could fold up. That's the explanation Dennis at Kolb gave me and after hearing 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 as it should. Feels like it has way to much compression and just bumps from stroke to stroke not able to spin it up. Any ideas welcome.

    well I attend the gym regularly with my Marine buddies who also have a hard time pulling the engine thru. With the plugs out, it pulls easy like it should. I had a 503 for 20 years and it never pulled like this. The pull starter was removed and checked out fine. Pistons look good as they should thru the exhaust ports. Put the plugs back in and major compression. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=430848#430848

    Do you know the history of this engine? When was it last run? If the engine sat without proper storage procedures the pistons may have corroded, sticking the rings. If the rings of both cylinders are stuck the rope will be quite hard to pull. There will be no noticeable compression events, just a steady hard pull. Pull the exhaust, use a light, rotate engine and inspect the piston and rings. I have seen the pistons white with corrosion and completely ruined after just 1 season of neglected storage.

    I had mud daubers make there way into the combustion chamber of a 447 that sat for some time. Mad it really hard to pull through, i.e. impossible. I pulled the head, cleaned it out good with a vacuum, then pulled the barrels to make sure there wasn't any damage to the rings or mud anywhere else. Once back together it was much easier to pull through and ran just fine.
