Twinky Posted March 19, 2011 Author Report Posted March 19, 2011 Well....... After a shitload of gaskets and countless hours of stuffing around... It was the carby.... All this time....... One thing that i noticed when I pulled it apart was that the inlet manifold was warped and covered about 3-4mm of the ports, thankfully I had a spare that matched perfectly. I changed, machined flat every part of the intake/exhaust system and it still ran like crap. Changed every bit I could on the carby and still no propper idle. So I went down to u-pull it and grabbed a carby from a KE70, the one that has a million hoses coming out of every direction. I stripped off all the stuff it didn't need and put it on. Started first pop, idles smoother and runs sooooooooo mutch better then ever. The carby is completely different to the KE55/30 4k/5k units. The throttle cable setup is different, thank god they provided provisions to run a manual choke amongst that monstrosity of an auto choke. I couldn't transpose the 4k linkages to the new units because the shaft is a couple of mm thicker. I can even screw the idle mixture screw and actually get a decent range of engine rpm. I am soo happy with it again that I ended up buying a cannon muffler and new resinator for it. It pulls up hill soo mutch better now. I would say that it goes up hill faster than the old 4k went down hill. Quote
Twinky Posted March 19, 2011 Author Report Posted March 19, 2011 (edited) Here is a pic of the missmatch. Look at the left hand side where the exhaust and inlet meet at the top. A closer look. If you look closer you can see that the manifold is not center on the mount, you should be able to see the lip. The new inlet. And the present I bought my rolla: Short cannon muffler 2 1/2" with standard 1.5" exhaust plus a 1.5 x 12" resinator. I love the new note it gives off. To the untrained ear you can't tell the difference from the old one. But... This exhaust is quieter at idle and does not drone on light throttle. This is the old exhaust. Long Cannon muffler 2.5", 2" all the way through exhaust with a middle 12" muffler from a commodore. Drones like a mofo. If you play the videos both together and fast forward to the hard throllt point and listen to them straight after one another you will notice the difference. Lol spot the difference (not the exhaust), win beer! Edited March 19, 2011 by Twinky Quote
