Go devil questions.

Ok guys I have a few questions. First off I'm relatively new to mud motors. I have had a 6.5 hp do it yourself long tail on a small jon boat and then this 31 hp go devil long tail. This one seems to be giving me more problems but it is older and I'm new to this. First off I had the problem where the motor was not running good at all and stalling out. Realized I did not have a gas cap with a breather on it. So i got a new gas cap and bam problem fixed. Then I'm out a few days after getting it and I was running WOT and hit a log and it jarred the engine out the water the engine kept running but Immediately sounded different and I had absolutely zero throttle response. In fact when I would try to give it throttle it would start to stall. So i limped it back to shore. I pulled the top plate off once I got home and seen that the rod connecting to the throttle was off and just laying there. Also I realized I lost a spring in the back of the throttle setup on the engine. So i ordered a rreplacement and decided I should get spark plugs and a fuel filter while I was at it. So i changed the fuel filter and then I was changing the plugs only to realize the guy I bought it from had the wrong plugs in it (he had the short ones instead of the long ones for ohv) and man they were black. So i replaced the plugs with new correct plugs. Now the motor starts and idles good. Still no throttle response. Any ideas? Also I let it run for around 4 or 5 minutes in my driveway. After that I noticed inside the muffler it was glowing red. Is this normal. It was very shady and cloudy where I was at maybe that's why I noticed it. Also where the prop attaches to the shaft there is a stainless steel piece around 2 or 3 inches long. That was warm. Not hot but warm to the touch. Is that normal after a few minutes of running at idle out of water? Could this be a carb issue? He claims to have just had the carb cleaned and prior to hitting the stump this engine ran great. Could I have knocked something loose and that fouled out the wrong plugs that were in it fast? Any help is appreciated. Thanks.

It's your fetser valve! Get some 3 n 1 oil and some gauze pads honestly I'm not sure but you're runing way lean so stop! It's definitely a fuel issue. Your not getting enough fuel. Could be pick up, filter or a number of thing but its fuel. I'm sure you'll get good advise here but don't run it that lean.

I tore into the motor last night. I took the carb off and inspected everything it looks good. I did notice there was some fuel in the carb right where the intake hose comes to the carb I don't know if that is normal or not. Everything appears to be ok. I'm not sure why I'm running too rich. I did notice a few spots on the carb with wires running to it. Could them ever go bad? I'm still going to clean it up and degreaser the whole engine and clean everything up and reassemble everything. I'lltry that and see what happens.

Ok after scratching my head for the last few days and researching the Web I read to smell the oil so I did and bam a big smell of gas. Somehow when I hit the log I must have shifted somthing and gas is in the oil. I'm so confused.
