tell ya what. i rebuilt my carb a hunnerd times and never got it right. there is too much crap goin on inside teh stock carb. (is it the hitachi?) i found multiple problems with my carb that i couldnt fix. also, the rebuild kits are incomlete. no accelerator pump, but you get a shiny new dust boot for your old one
. there are other things missing i cant think of right now. if you have the money or if you can save it up, i suggest going here.
http://www.carbs.net and click on the weber picture right below the main page menu block. tehy have an application guide with complete kits for luvs. i paid a atotal of 340.00 bucks for my weber kit and have enjoyed it ever since. n e way, that is all i have to say about that
