i have a 35 mudbuddy but it is not stock it is backfiring through carb can anyone help it also is overflowing fuel through overflow port on carb have been through entire engine and cant find problem please help seth
I agree, stuck float, take completely apart, clean float needle valve seat and try that, also try to get all the trash out of the gas tank and install, if it dont already have one, an inline filter between tank and carb, good luck!
I have a 35 Mudbuddy thats no where near stock that did the same thing. I took the carbs apart and found nothing wrong. Did some adjustments to the idle screws and the backfiring eventually went away. It stills pours gas out of the vent tube when the engine falls to one side. Havent used it in the last year due to work so I havent tried to fix it. If you need some help contact Rick at the Boat Doctor in Harahan. Always helps me out.
thanks for the insight everyone. i am a capable machanic this engine is high performance. the carb is not the issue. i need some advice on any other ideas that could be the issue. this engine turns 8200 rpms in the water so nothing about it is stock. i need someone with a high level of mechanical intuition thanks
I problaby don't have the knowledge you have so I won't suggestion anything. I would love to know what you have done to get 8200 rpms. I did the single carb upgrade and the Stainless exhaust but am scare to turn over 4300. Where can I find out what is safe to turn and do you have any other suggestion starting with the cheapest or biggest bang for my buck?
bent valve or push rod, and if you are turning 8200 rpm like you say you are your lucky if thats all you got. high performance or not 4200 is about the max you should run that engine, you may go 5500 and get away with it for a while but your asking for trouble. you neeeeeeed to put pitch in your prop or get a bigger prop. call hopkins propeller hell make you a prop.
