Ok, I think I might have found the problem with my loss in MPG ... I went to re-build the crab on my '85 brat and discoverd BIG chunks of black plastic in the air filter that had obviously become molten and some had even been sucked down the barrel of the carb!!

 

I am not sure what the component is that started to burn up and get sucked in, but it has a 1/2" line connecting it to the air cleaner, and the other side of it goes into the left cyl head. It has two branched out pieces that look like they would connect somewhere on a different model, maybe a CA model, and these branches just dead-end and look factory. This valve or what ever it is looks like a top and has the extra "branches" comming out the top. I would take a pic of it but I just moved and I am not sure where my digi camera is ... anyone have ideas what would cause this problem or what this componet is?

hmmmm ... some good info there, but does it apply to the EA 81 motor as well? If it is my ASV, it looks completly different than what I have, and it's entirely made of plastic ... I guess I can just plug the line before it leaves the head? I am also concerned what is causing the back-fires (mine are almost impossible to hear) and I am currently searching for a good re-build kit. I got one that was sooooo close! but the size of the gaskets were off ... and now the guy says they don't have any other kits to order!!?

 

 

If anyone can give me the parts store and part number for a good kit for a Hitachi DCZ-328 ? (EA 81 carb)
