I haven’t had my boat out for a while because of the hours at work but the last time I had it out it wasn't running too good. Previous post about it here: http://www.catfish1.com/forums/showthread.php?t=21080 I thought I had it fixed but when I took it out it still didn't run real clean. It was hard to keep it idling and it only had slow idle and fast. It would crap out real bad and then kick in and run great at full throttle almost instantly. I just put it up until tonight when I finally got some time to work on it. I pulled the carb off and apart and cleaned it the best I could with two cans of carb cleaner. I'm going to flush the gas tank tomorrow and add the inline fuel filter with some new gas as well. Who knows if it will run better or not? While I was at it I pulled the two plugs and when trying to put it back in I noticed one plug hole had a thread broke lose. I discovered that both holes have had inserts put in it so I pulled that one out and added a new insert. Well the tip of the insert broke off inside the cylinder before I could grab it will pliers. I turned the motor over a few times to try and blow it out. Is it possible that this can go out the exhaust hole? I looked in there with a flash light and didn't see it any where. I was hoping to fire the motor up tomorrow and see if it is going to run any cleaner but now I don't know if I'm going to have to pull the head or what. One other thing while I'm posting. I pulled the bowl and sprayed the jet holes and everything out real good with cleaner but after looking at pic 12 in Bobpaul's carb tutorial; I noticed this carb didn't have the low speed pick up tube inside it like in the picture. Is that only on some of the larger engines?
