SuzukiSavage.com - Flooding carb during warm-up idle

Put it all back together, and the bike's sitting in the garage purring away like it hasn't been causing any headaches at all in the last week or so.

I get this is where we all got confused, to quote you, " However, adding throttle to it will cause the carburetor to flood and overflow."

If the vacuum line is broken, it shuts the fuel off to the carb and you run lean. However in your case it flooded and over flowed? It should have also run fine in the prime position, the same as with a good vacuum line in the on position.

Before replacing the vacuum line, I did run it in the "Prime" position, and it ran just fine.

But yes, with the cracked vacuum line in the "On" position, the bike would cough and die unless you grabbed the throttle and opened it up, in which case it would flood the float bowl and overflow through the overflow tubes.

Well, it seems that what I did yesterday was for naught, as the bike started doing the exact same thing as described in my OP this morning when Mrs. Jman started it up to go to work.

For now we just switched the petcock over to "Prime" so she can use the bike, but this whole thing is now confusing the hell out of me.

I guess I'll be replacing the petcock after all...after payday.

Re: Flooding carb during warm-up idle Reply #19 - 07/15/14 at 06:06:04 When I first bought my Savage it did something similar, it would would only run correctly if the petcock was set to prime. I replaced it with a raptor and have had no further issues.
