TC10284 109 #1 Posted July 31, 2018 (edited) I have a 3114k804 414-8. I recently fixed the wiring on it to the ignition switch. I also had the carb cleaned and ran a new fuel hose. Put fresh gas in it. Turns over fine but won't start. The only time I can get it to start is when I squirt gas into the carb and it will run until it burns it out. I've also replaced the fuel pump with a new Kohler brand one. When I take off the hose going to the carb and turn over the engine, it squirts gas very well. So I'm not sure why it's not running yet. Does anyone have a manual for the carb? I'm looking for the correct screw rotations for proper air to fuel mixture and idle speed. Also, the carb is a Walbro brand.

pfrederi 17,143 #3 Posted July 31, 2018 Here are the settings Carb cleaning has different meanings. To some spraying some stuff into the carb means cleaning. In reality you have to take it off the engine disassemble it and soak it. 1 Share this post Link to post Share on other sites

I remember the float was stuck but it isn't anymore. Only other thing to be done in regard to cleaning is letting it soak. Share this post Link to post Share on other sites
pacer 3,159 #5 Posted August 1, 2018 My guess is its the needle valve - you say you have already had problems with it and from your description seems thats about all thats left. I ordered a new needle/seat once, installed it and engine would not start and like you it would start with a squirt of gas into the carb. After fooling with it for some time I finally had to accept that float was sticking CLOSED! - I had NEVER seen that happen. Sure enough I got another needle/seat and --- problem solved 2 Share this post Link to post Share on other sites

TC10284 109 #8 Posted August 1, 2018 (edited) Update: I was able to get it running on its own. However, I cannot get it to go above half throttle with the choke all the way in. I have to have the choke out over half way for it to run at full throttle. I have tried adjusting as many of the screws as I can in and out, and it doesn't seem to affect anything so far. One more thing, it doesn't have a gasket between the carb and the block. Edited August 1, 2018 by TC10284 Share this post Link to post Share on other sites
pfrederi 17,143 #9 Posted August 1, 2018 Lacking a gasket is a big thing. Lots of air gets sucked in and leans out the mixture. Do you have a Kohler carb or a Walbro Fixed jet. You could make a quick gasket and see if that helps things. Use gasket material or a manila folder...NOT RTV silicone. 1 Share this post Link to post Share on other sites

It didn't come with one. I need to order one. There are three screws I can adjust. Edited August 2, 2018 by TC10284 Share this post Link to post Share on other sites
