Ive got a 95 Magnum 425 that backfires when you release the throttle after holding it steady for a bit. If you gently feather it to slowly reduce engine speed it seems okay. It seems to load the cylinder with fuel. Any suggestions?
I just bought this and otherwise its a great ride

Also check throttle cable play,too muck slack can also cause backfiring. 1/16-1/8" slack

Thanks Guys
It seems hard starting at times. Almost like it floods. Perhaps the floats or needle is sticking

 

Was the oil changed the way it should be before you bought it? If not, the cam may be going out of it. Look at your oil and see if it smells like gas, if so, it could be the cam.

 

vibration sometimes causes problems with the needle or seat in the carb. Search the forum and there is some good info about the issue. I've also seen the carb itself crack and cause issues which mimic a bad cam. If you pull it to check the internals make sure to closely inspect the body of the carb itself.

 

Thanks guys
Will do

 

could it just be running lean, check and see what ur spark plug looks like as far a color, it it's white, it's lean, if it's black, it's rich. i'd check that before goin to far into it
