1983 dt85 issues giving throttle

[Jhayes780]

OK guys so if you followed my post, it’s been a long run but I finally got the boat in the water today. It putted around 5mph zones like a champ. Changed directions and shifted seamlessly. Once I got it going about 30 min had gone by and I decided to open it up a bit. I did not go WOT but probably 3/4 and then it just died and acted like it was staved for fuel. I got it started again, went to half throttle and it died. Got it started again and then had to go all the way back at a putt. Then it died in nuetral. Any ideas what is going on?

who really knows, but usually dying whan advancing the throttle means carb problems.

running too lean at idle and it has a hard time transitioning to the open throttle.
or the jets passages on mail jet has a problem.
there are off idle ports that need to give fuel also as the throttle is opened
