Need a few ideas/pointers. I got my 1450 when the PO was tired of adding more oil than gas and had no power. I rebuilt the engine in February 2012 and the hour meter read 150 hours or so I wrote in the log. The rebuild included bore and over size pistons, valves etc. In the year and 1/2 I have now 200 hours on the meter. So I've put 50 hours on the tractor since the rebuild. Today I started the tractor and moved some other equipment to make preparations to install the snow thrower and cab for winter. The engine began smoking excessively as soon as I started it. I used the tractor maybe a month ago for a few hours mowing about two acres and didn't notice any smoking then.
What would you guys do before I should consider pulling the engine and looking at the rings etc?
