Joshyg 32 #1 Posted March 21 Does anyone know why my c145 runs full throttle but dies out a little under halfway Share this post Link to post Share on other sites
Easton Rich 1,222 #2 Posted March 21 Sounds like your carburetor has some dirt or debris in it. I would remove it, soak it in gas and disassemble to inspect and properly clean it. Share this post Link to post Share on other sites
Joshyg 32 #3 Posted March 21 It has a pretty new carb but it could be dirt Share this post Link to post Share on other sites
pfrederi 20,532 #4 Posted March 21 (edited) or a Chinesium carb...some of them do not work well.. Clean it to start with also see if your fuel pump is pumping.... Edited March 21 by pfrederi 1 Share this post Link to post Share on other sites
Joshyg 32 #5 Posted March 21 I read somewhere that there was a certain carb that worked really well Share this post Link to post Share on other sites
Joshyg 32 #6 Posted March 21 I need to buy an air filter too Share this post Link to post Share on other sites
Brockport Bill 2,341 #7 Posted March 21 can be debris in tank -- although hopefully your fuel filter catches that -- also if you have not changed fuel hose in awhile you may wish to do so because small fragments that deteriorate from inside fuel line might clog a carb?

pfrederi 20,532 #8 Posted March 21 You might try running without a filter see if it runs better I doubt you have much dust right now Share this post Link to post Share on other sites
Joshyg 32 #9 Posted March 21 I actually just put new fuel line on it Share this post Link to post Share on other sites
Joshyg 32 #10 Posted March 21 (edited) It currently doesn’t have an air filter Edited March 21 by Joshyg Share this post Link to post Share on other sites
Easton Rich 1,222 #11 Posted March 21 I bet it's your new carburetor. They are a 50/50 whether they work or not. @76c12091520h might have a rebuilt one you could purchase 1 Share this post Link to post Share on other sites

Joshyg 32 #13 Posted March 21 Is there any chance it could be my spark plug 1 Share this post Link to post Share on other sites
953 nut 66,020 #14 Posted March 22 Whenever a new problem comes up you should consider the last thing you changed and be sure it was done correctly. 2 hours ago, Joshyg said: runs full throttle but dies out a little under halfway This is a symptom of poor fuel to air ratio. is the new carburetor mounted tightly with a new gasket? Have you adjusted the high speed and low speed screws as suggested by the supplier? Share this post Link to post Share on other sites
Joshyg 32 #15 Posted March 22 (edited) Yes. I can get to start in idle by engaging and disengaging the choke so I know the fuel mixture is lean. Could it be the float? Edited March 22 by Joshyg Share this post Link to post Share on other sites
Easton Rich 1,222 #16 Posted March 22 You'll want to adjust it to richen your air fuel mix. The top needle on your carb is what does this Share this post Link to post Share on other sites
oliver2-44 11,478 #18 Posted March 22 Just a thought, do you have the old carb? I have had some Chinese carbs that would run full throttle, and idle like crap, others idled good and wouldn't run full throttle Share this post Link to post Share on other sites
Joshyg 32 #19 Posted March 22 Yeah I have the old carb Share this post Link to post Share on other sites
Joshyg 32 #20 Posted March 22 (edited) Should I clean the old carb? Edited March 22 by Joshyg 1 Share this post Link to post Share on other sites
Easton Rich 1,222 #21 Posted March 22 Yes, break it down. There are some good threads on here you could do step by step to rebuild it, or there are some good youtube videos on it I'm sure 1 Share this post Link to post Share on other sites
