I wanted to get my 226 started. I ended up pulling the plugs and they all looked decent. A little fouling but nothing too bad. I poured a little rotella in each cylinder and let it sit for two days. When I went back I bumped the starter then put the plugs back in. I bypassed the fuel pump and used a gravity fed bucket straight to the carb. The engine started right up with a couple revs of the starter. It seems to idle pretty decent but there was some blue smoke coming from the filler tube and the exhaust. I ran it for a couple minutes and all seemed ok. I went back today and she started right up and idles fine. She smells like she is running rich at idle but no black smoke just blue. I changed the oil and pulled the plugs. The oil smells like gas and the plugs look dark and oily. I switched the plugs and ran her with the new oil for ten minutes or so. She runs fine but still smokes. The smoke gets worse when I give her throttle but then dies back down at idle. I wasn't too worried about the smoke since the engine has been sitting for 3 or 4 years. The carb isn't the original. The engine wants to choke if I don't ease into the gas. Any opinions? I haven't done a compression test and I don't know what the oil pressure is. The thing runs well and starts well it just smells rich and I have blue smoke. Not billows but it's more than a little haze. If someone could point me in the right direction that would be great. I'm not sure if the fouled plugs was just residual rotella. I might need rings. I just need help diagnosing the thing.

 

A compression test would be a good place to start. You may have some gunked up or stuck rings from sitting so long. It probably just needs to be run. And maybe the carb needs a look if it is dumping too much gas.
