[cub149]

Hi all, I have come here from the another CC site. I was a reader with a few questions now and then. BTW, I really like this site!
My question today is about my 149. I have owned it for two years now and it has never let me down but it has always had blow by from the dipstick. Now it has some smoke from the exhaust, not terrible mostly when starting or under load and it's not a heavy smoke. It runs good with no knocks, pings, etc.... Would this be valves, worn rings or both? It also uses about a 1/4 qt or so of oil after mowing 3 hours with it. What will it eventually do, just quit or will it slowly start loosing power and compression? As you have figured out by now I don't know to much about working on the engines. I have just never took the time to tear into one.

I am just trying to get by with it until I find one of two tractors to replace it with. One is a CC and I can't mention the other on on here. I will be keeping this one and probably take a shot at a rebuild once another is secured and in service.
This is not my first CC, I had a 1650 that broke a rod and I sold and then regretted it and found this 149. I can't decide which I like the best. I am a little tough on them but do keep up the maintenance.

I know it's hard to make a diagnosis without seeing and hearing it but take a shot. Tell me what to look for or at.

Thanks
