Hello all! Have not been on in long time. (Life lol) Anyway my sp450 is still parked. Having an issue with it. The thing will start NP, it will if given a small amount of throttle, throttle up. If you try and rev it up it bogs down. My friend as we speak, is taking the carb appart to clean jets. We have down this b4 with no change in how it acts. Asking for any help or ideas on what to check. What to replace or anything we shld try. Ty in addvance for helping!!!

 

Did you check all the air breather hoses and air filter?
Try starting it up without the filter and the cover off the breather box first.......Caper............

 

you said it will start right up and will it idle good? when you say it bogs, is it like the override bog in reverse w/out pushing the buton? did you try leaving the choke on to see if it helps or makes it worse? how long has it sat and did you have the gas stablized?

 

fuel filter... fuel lines....... air filter..... and the carb is the only thing i can think off. if it was spitting and spuddring id say the over ride. but it maybe i kinda doubt it.
