W/H JUNKY 43 #1 Posted August 25, 2015 Needing a alittle help. Tried starting up my commando 8 after restoring and rewiring this tractor. It has great spark, new fuel but just will not fire up and run. I have tried starting it with carb cleaner and starter fluid but still will not fire up. After cranking it so long that fuel starts coming out the front of the carb.So i know it is getting fuel And smoke is coming out of the muffler. Now this tractor ran before restoring. Thanks in advance Share this post Link to post Share on other sites
squonk 38,988 #2 Posted August 25, 2015 What's the compression? You need 3 things to run. You have spark and fuel. did you check compression? Maybe a valve too tight and hanging open or sticking. Did you take the motor apart? 3 Share this post Link to post Share on other sites
W/H JUNKY 43 #3 Posted August 25, 2015 No i did not take it apart i will check the compression. Would you happen to know what it should be. Share this post Link to post Share on other sites
squonk 38,988 #4 Posted August 25, 2015 It has an automatic compression release so an accurate reading is hard to get. I'm thinking 50 psi minimum. 1 Share this post Link to post Share on other sites

buckrancher 2,675 #6 Posted August 26, 2015 sounds like a stuck valve check compression with the throttle wide openBrian Share this post Link to post Share on other sites
