ok my 720 will idle sometimes, but it is erratic (rpms change) and other times it wont idle at all.... truck sits alot.....was wondering if maybe the idle passages in the carb are gummed up...... never did get my weber from bigred620... so i need to make this one work for now

Sounds like wear- but also make sure the vacuum lines are all hooked up. Late Hitachis are VERY prone to vacuum leaks and work best when everything is hooked up right.

You can try kitting it but I've never been able to put one together and work right. The kits don't come with jets, and that's usually what's worn out on mine (along with the throttle bores, I only have 250K on some of mine)
