DCH340 Variations?


Recommended Posts

I'm currently rebuilding a DCH340, but the parts sheet I got with the carb kit shows a blow-up of a different carburetor than mine, even though it's labeled as for a DCH340. After searching thoroughly with Google, It seems as though there are 2 different carbs that people are calling DCH340's. They are both found on L20b's, which is where I pulled mine from.


Here is one variation(not mine):




And here is the other(the one I have):





Does anybody have any insight on this?


I'm also having trouble finding jet sizes for my carb.. wanting to make sure they're correct. Thanks!

Jet sizes changed for year to year, auto/standard, California/federal and the emission standards ... you name it. Very generally primary was 99 or 100 and secondary was 150-160. This will run but may be ever so slightly lean or rich favoring economy or performance. You would need a dyno and a wide band to tell the difference.
