    mule 610 4x4
  1. I think it must have something to do with firing, could be wrong. Runs much bettet.
  2. Just an update from several months ago. As noted had carb cleaned and air filter changed and helped a lot but have had plug foul twice in several months. Battery was weak and finally died so I replace it with a lawn mower batter i already had with a little mod to the hold down device. Mule runs much much better and has not fouled a plug since, have pulled the plug several times to inspect and no where near as black and suttey as before so I am assuming the weak battery was the cause or at least a big part of it. What U guys think? Thanks and b well
  3. Sorry for late response for some reason I don't get an email , mule is doing good, prob. 7 hrs run time no issues.
  4. Update: Have driven mule about 15-18 miles at about 3 hrs on clock and plug looks pretty good and oil level is OK. Will update as I get more run time, I think it is important to update these post so others can get info for similar problems they may have. Merry Christmas to all
  5. Got the mule back late yesterday and guy said he cleaned carb and replaced needle valve and set float. Hopefully this will solve the gas in oil problem. The fouling of plug was due to the foam air filter. It was deteriorated and when wide open throttle it pulled it into paper filter and starved mule of air causing more gas than air and foul plug. Haven't had time to run mule any so will report back when I have run time.
  6. Took mule to my mechanic who has worked on several mules in the past and let him see what might be the problem. I have read on several different places that the mule is bad about fouling plugs for whatever reason. I will update when get mule back with what he found and hopefully fixed.
  7. Yes exactly I'll keep an eye on it, thanks.
  8. I have a fairly new fuel pump on it from a previous repair and It maybe the needle valve. I will monitor the oil level and see what happens. Thanks again
  9. Not sure about transmission but I think it is mated but it has a red fluid in it 80-90 weight and I checked it. It has a separate reservoir and dip stick. It was a little low but not bad so I topped it off. Also changed oil only no filter, took just a tad over 1 qt. I measured oil drained out and it must have been at least 1.5 qts. Mule is making oil, LOL. Will monitor and see if it stays at current level. Thanks again
  10. Kinda hard to tell about gas in oil, didn't smell to much like it had gas in oil but could be wrong. Last time I changed oil I didn't fill with oil before installing. Have had a problem with plug fouling after about 2 hrs meter run time, plug will be black as sut, no oil or gas smell on it just really black. Wonder if the two are related. If gas is in oil what could cause this, maybe carb. letting gas flow by. Thinking of putting in a gas line cut off, that should eliminate that concern until I get it my mechanic to look in to plug fouling. What you think and thanks for responding. Mule has 360 hrs light yard use only.
  11. Strange issue and it has happened twice. Changed oil twice and after a while when oil is checked it is always to full on dip stick. Looks like at least 1/2 qtr. I have looked at manual and put in amount called for, 1.16 qt without filter. What would cause level to appear to full. Thanks
  12. Yea I may set valves to loose .006. I have a hotter plug and closed gap to ,025 instead of .030. I have almost an hr. on the clock run time and hasn't fouled yet so we will see. Mule only has 350 yrs so not worn out and has been taken care of by me since owning it about 7 yrs. Thanks again for replying.
  13. The valve specks are .0039 to .0059 and dealer told me initially they set them a little tight and I didn't question it. I hate to hear a valve tick but I may set them at .007 and see what happens. Funny it didn't foul until dealer tightened them down to around .002. Again I have read on several sites that the mule is bad to do this and my friends does same thing. I always run no corn gas and add seafoam or marvil mystery oil. Thanks for reply
  14. No smoke and doesn't smell like the carb is rich exhaust muffler pipe is black. I ran it out on the road for about 3 miles and pulled plug and it looked pretty good. Like a lot of guys my mule idles a lot and puttering around the yard a lot so not a lot of wide open throttle. My friend has a mule just like mine and it does same thing. When I bought the mule used it had a valve ticking but ran fine. I ran the mule like this for probably a yr or so and never fouled a plug. Took it to a dealer and they adjusted the valves and that is when the plug fouling began. Have had dealer re-adjust since then and same thing. I went in and checked valves myself they were about .002 and I loosened them up to .005 and am going to see if that helps before I do the carb cleaning adjusting. Thanks for your replys.
