I have a 98 dyna lowrider. Stock evo motor. I live in California at about 3500' elevation. A typical ride will take me down to about 500' and back up to 3500'.
It runs lean with the factory settings. It does not idle unless I leave the choke about 1/4 the way out. It has a hiccup when I dip into the throttle during a steady cruise. Its much less a problem at the lower elevations.
It's my understanding that a california carb has the adjustment screws (enrichment, idle) capped off. This is the case with mine. My brother in ohio sent me the carb off his 2002? street glide. It's off a twin cam 88 and has access to the adjustment screws.
I'm looking at being able to adjust the enrichment depending on where im riding using my brothers carb.
Am I barking up the wrong tree? I know u guys are smart. If you get a minute, please help a fella out. Thanks

 

If you haven't been thru the carb might want to go thru and give it a good cleaning and check over and also check over the slide diapham or just replace it. Check or replace your manifold gaskets as they may be cracking and causing a lean conditiion. Your brothers '02 carb also had that plug on the bottom of the carb. My '02 did and I carefully removed it with a drill and replaced the screw with a aftermarket one that I can easily get to for adjusting with no tools. If you can get ahold of one of the past American Iron Magazines and look for the "How it works" section on a artical from Joe Minton on the CV carb and setting all this up.
