My quad wants to die when I first hit the throttle the ripps on the needle and the main. It was running great but sputtering on the main so I looked and the carb was not opening all the way. Fixed it and wow I can finally run straight 110 with no pump. but now this. I have a 265 set up 39 pwk DGH needle on the 5th position 182 main and 55 piolt uni filter no lid I did have to cut the spring to get the carb to open up all the way but it is a spring I got at west lake and it was a little longer and the throttle return seems a little weak now. if you rev it a little it wants to idle high for a few seconds then dies down. any advise. I run straight 110 with klotts r 50 32:1

put the needle clip in center spot !!...try this 1st & not with any other changes

BTW the 39 carbs can be a POS for tuning ...& IMO too big for a 265 usually

I am pretty sure the needle is fine I started in the 3rd thats where I ran this summer It is 15 F out cold and it feels like it could even go fatter. My problem is right off of the idle.
