I have a hot B20 going into my car next week and I plan to feed it with two Dellorto DHLA 40s. I would like to tune the things myself but I cannot find any tuning parts anywhere. Does anybody know of any sources that are not KG Trimning? Also, has anybody had to do the tuning of these carbs and did you develop any successful methods? Tricks? Tips? Anything would be appreciated.

Also, I get the privelege of breaking in my new $4000 b20 in a couple of weeks and I have never done it before. Any instructions for me? I plan to run synthetic in the thing through a CM 4 micron filter, but I have hard that excessive filtration and super-slippery synthetic oil are a bad idea for a new engine. Supposedly the engine needs a certain amount of friction to actually break in. I just have no experience in this, so I thought that if I ask Volvo owners, they probably would be of better help than a Chevy how-to. Any help from first start up to extended break in would be GREATLY appreciated.

Thanks,
Josh
