I've done an internet search and come up with much of nothing. Could be me,could be lack of info on the web. Figure it's mostly me. In any case this forum seems to come up with some really obscure info so figure maybe this would streamline my search by posting here. Believe the LH-300 is listed on the box as Chevy w/Stromberg. The CS-305 doesn't even give that much info. Has a multitude of other applications and part #s available on the box but doesn't say what CS-305 is intended for. The boxes aren't much longer for this world and don't currently have any pics of the parts themselves. Any help identifying CS-305 and any other info on LH-300 would be greatly appreciated.
