yardsale find, says mac cat but its a tophandle 2.3 with an 18 inch bar so im assuming its a wildcat. pulled exhaust looked at piston and see no damage, and it has spark. fuel line was bad so i replaced that. started it and it was running and i was trying to tune it. thought i had it pretty close but i lacked handy wood so i used it on a branch above my head and all of a sudden it started belching smoke and died. will restart but refuses to stay running and smokes super bad. white smoke. does the chain oiler use the engine pressure or something and if it fails sucks oil into the carb?
