squirter too big?

[TMat]

I have a brand new 850 mighty demon with annular boosters. With the engine idling and up to temperature. If I lightly blip the throttle it will bog and then rev up, bog and rev up. Sounds like it's getting too big of a shot from the squirter?

Any ideas?

is that carb jetted 80/88?

Is thete any play in the pump arm between the cam & the pump housing lever?

I haven't checked the jet sizes, but it's supposed to be jetted 80/88. Do you think it could be jetted wrong from the factory?

I will have to check the cam to housing slack also.

I'd make sure your jetting is correct first. Then you can make a squirter change. I had to increase mine by .003 front and back. What size engine?

I'm running a 489 and .037 primary .040 secondary squirters. My float levels are dead on and so is my jetting. I'm at 2500 ft so my jetting will be slightly different than yours.
