Excessive fuel in cylinders

[WWIT]

Hi all new to the forum! I have a 98 Gtx that I was dumb enough to buy. It had a cracked resonator and that’s all that was supposedly wrong with it. It ran when I went to look at it. Fast forward new resonator, new starter, new solenoid. Went to test run it and turns over in jolts but not consistent to run. Bring it back to my shop and pulled the plugs, turned it over a massive amount of fuel comes out when cranking. Previous owner had carbs rebuilt. He did the removal and reinstall but had a shop do the rebuild. My thoughts, something stuck open in carb’s somewhere, return line and feed line mixed up. I can’t find a decent diagram on what goes where off the mikuni carbs. Thoughts? Thanks in advance

You'll need to take some pictures of your current fuel connections. Is the ski a GTX limited?
