I have a 1997 250 trail blazer i had it bored 1.5 over should i do anythang with the carb. Also i wont to just mix my gas is it ok to do this

 

if your gonna pre-mix your gas your gonna need to disconnect the oil pump, and as for the carb i would think you would have to add more fuel since the cylinder is bigger now and sucking in more air. but i dont know where to tell you to start.

 

Cld maybe contact http://www.rittercycle.com/ and see what they say? I hear good things about them.

 

I plan on using them to rebuild my wifes motor this winter. And maybe a hop up or two lol.

 

With a bore out you shouldnt need to rejet the carb.
