As some may know I recently purchased a Bolens 600 with front reel mower. I brought it home and it died out on me and wasn't getting fuel. I called my "supplier" Brian and got a carb rebuild kit, new fuel line, inline filter, fuel shut off valve, and a new plug. I installed everything on Wednesday and it fired up. But here is the problem. It fires up and I can't bring it down to a good idle. Its current idle is like 1/2 throttle right now. If I raise the throttle the rpms run away on me and I'm scared the thing is gonna blow up. I can adjust the carb(turn out the bottom mixture jet) so it idles down lower, but I think its only doing that because I'm making it way to rich and it puffs smoke and spits and sputters and wants to stall. I can adjust the jet in so it smooths out, but then the rpms just want to run away on me. I've reviewed all this with Brian, and he gave me a few ideas, but I was wondering if anyone has experienced this issue before and could maybe give me their input. What I'm currently looking into is if the spring that hooks from the throttle plate/shaft at the top of the carb through the eyelit of the metal carb cover is the wrong spring. It seems very loose and too long. I wanted to purchase a new spring, but they are NLA. Brian found me one on ebay, but I was trying to see what others think about the spring, and if it could be the spring tension or lack there of causing the issue. If some fellow 600 owners could take a look at their springs to see if there is tension on them or if they are loose with the throttle all the way down that be great. I'm also looking at the linkage between the carb and the governor. If anyone has pictures of the spring and linkages, I'd greatly appreciate the help. I want to get the little 600 running and try the reel mower out. This thing is kicking my butt!! My grass is pretty tall already, and my wife has been bugging me to mow, I don't want to have to do it, but pretty soon I'll just have to push it aside and get the new tractor out to cut the grass if I can't get the carb figured out. Thanks in advance!
