"David Martel" wrote in message nk.net... Where would I give it the starter fluid? Sorry. Remove the air filter and give a big squirt straight down the carb throat. Have played with the needle valve and got it to the point where starts but it won't ever tick over until operating temperature is reached. Yes, it is now misadjusted. Screw it completely in and then out 1 1/2 turns. Clockwise will increase idle speed. You are correct it is an end-stop. If the screw does not touch metal. then investigate the throttle cable and the linkages. It would be very unusual for the linkage springs to lose "springyness". I don't understand your question about the choke. The choke should be controlled manually, usually by a lever. No, this B&S, has the choke-o-matic carb where the choke is naturally shut, but opens via vacuum acting on a diaphragm between the carb base and fuel tank under it. It will have a main fuel mixture screw and idle speed screw. As you say base setting is 1 1/2 turns out with a 2/3 ful fuel tank. This is important. Mixture strength varies with fuel level (yes, crap B&S design!) Usually have to set them slightly on the rich side so they'll accelorate cleanly from idle (which should be a fastish 1750rpm) without dying, yet run at full speed without being too rich. Tim.. |
