I would look at the rubber boot between the carb and intake. Even if it doesn't have any holes the clamp can only be tightened up so far and the rubber gets weak after a while..Just my opinion though...

 

I had the same problem, simple fix remove the carb and clean the hello out of it. There is something clogging one of your jets, or check that intake boot. Mine did it after the engine was rebuilt??? So i was really confused long story short carb was really i mean really clean but had one peice of trash floating around clogging things up.

hope this helps

 

You can fix this problem with a standard click type ink pen!!! This is a very common problem to the Warrior carb, the 1995 Wolverines had the same carb, and I went through the same thing. The problem is your accelerator pump spring. If you take the carb off, and remove the bowl, you will find a rod with a plunger on it, with an ungodly weak spring slipped over a nub on the bottom. What Yamaha was thinking with that spring, I will never know. It takes almost nothing to jam the rod down, no shot of gas when you hit it hard, carb gets a big shot of air and no extra gas, stumbles and almost dies. take the old pen spring,it is the same size,but 5 times stronger, replace and reassemble, and the rod will never get stuck again,unless you get some dirt in there. Mine was horrible for this, now,several years later, has never happened again.

 

now this is a excellant idea and well worth reading this fix , great idea , I am sure many on this site he will do exactly that ,

 

junk carb. get an edlebrock for it to make it run right. its gonna set you back about 300 ponies, but it would be well worth the change. just my 2 cents.
