Here is a PDF, (quality not the best(, on the Hitachi Carbs. I think the jets are push in and remember reading they can be removed by cutting away a bit of the tower to b able to get a purchase on the jet to remove it. Wouldn't go to deep.

The carb T has o'rings each end. Wouldn't b hard to get fuel resistant replacements.
From fleecebay.

2 things come to mind on the fuel leak. 1st could b a stuck float or float needle has some dirt on the seat.

2nd could b leaking petcock in conjunction with float or dirty needle seat

If fuel has been running out the carb it will pay to check it hasn't run into the engine. Check the oil for fuel contamination..

Okay I will give that a check, for the leak it's mainly leaking from the t link because of the o ring, idk if it's leaking, but there is gas coming from the screws on the side of the carb the one that goes into airbox. I remove the bowl and spary some carb cleaner.

The screws mentioned, are they the ones in the bell housing I can see in the pics. If so, they are jets. Have a look at the PDF for the carb diagram semantic.

If timing or valve clearances are too far off it could push fuel back out the jets or belmouth.
