Guys,

I have a 400 Kodiak that falls flat in its face when i punch the throttle. And when i hold it wide open, extreme backfiring takes place!! I have ran some Sea-Foam through it, and that has not changed anything. I am assuming it is the carb, since one night i came back to the shop and a puddle of gas was nicely spread across the shop floor! Any ideas?

 

I'd start with the float. The gogging sounds typical of a flooding problem. the float could be hanging just enough to not seal off and come out the overflow, thus the puddle in the floor over time. Hope this helps.

 

float stuck open...thanks why gas keeps pouring and comes out the overflow tube and onto the floor

 

Didn't have fuel on the floor, but had the same issue. Wide open, it would cut out bad. Had idleing issues also. Just had carb rebuilt and WOW!!! My 2000 Kodiak runs like it came off the show room floor.
