Easton Rich 1,064 #2 Posted yesterday at 09:46 PM 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 0 #5 Posted yesterday at 09:52 PM I read somewhere that there was a certain carb that worked really well Share this post Link to post Share on other sites
Joshyg 0 #6 Posted yesterday at 09:54 PM I need to buy an air filter too Share this post Link to post Share on other sites
Brockport Bill 2,242 #7 Posted 23 hours ago 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 20,012 #8 Posted 23 hours ago 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

Easton Rich 1,064 #11 Posted 23 hours ago 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

953 nut 64,485 #14 Posted 21 hours ago 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 0 #15 Posted 21 hours ago (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 21 hours ago by Joshyg Share this post Link to post Share on other sites
Easton Rich 1,064 #16 Posted 20 hours ago 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 11,284 #18 Posted 6 hours ago 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 0 #19 Posted 6 hours ago Yeah I have the old carb Share this post Link to post Share on other sites
Joshyg 0 #20 Posted 6 hours ago (edited) Should I clean the old carb? Edited 5 hours ago by Joshyg Share this post Link to post Share on other sites
Easton Rich 1,064 #21 Posted 4 hours ago 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 Share this post Link to post Share on other sites
