GXT 804 utility, air box flooding
I have an EZ-GO GXT-804 with a 2 cylinder Robin Engine. The engine ( EH29C, 295cc) runs fine normally but when under load the engine starts bogging down and the Air Filter housing gets fuel it it, you can see gas going out if you leave the air filter and the housing cover off. I currently have to run it without the air cleaner and air housing cover.
I have already done the following, replaced the: Carburetor, Spark Plugs, Coil and wires, and set the valve clearance to .004 cold. I checked compression on the cylinders and its about 155. Its currently not blowing any colored exhaust so I don't think the engine is shot. any thoughts? someone I just spoke to the other day said the muffler could be causing the blowback of the gas through the carb. any assistance would be great. there is nobody in our area that works on these carts anymore. great cart when the carbs not blowing out gas.. :-) thanks Jason |

Re: GXT 804 utility, air box flooding
Did you notice more threads where you adjusted the intake valves ? Maybe take a picture under the valve cover and upload it here. These robbins are famous for pulling the intake valves in head. The two center valves are the intakes.
A timing belt out a notch or two could cause your issue. A plugged up muffler would indeed cause it to blow back gas out carb but these engines are not known for that. I guess it you were careful not to break the two bolts that hold the muffler on you could remove them and see what happens. I warn you if they are tight you will need a torch or pop they go. |

Re: GXT 804 utility, air box flooding
The Robins 295/350 are notorious for "wearing out" with high hours. The timing belts and valves are common, as well as the #2 connecting rod from oil starvation. Any idea how many hours on this engine? |

Re: GXT 804 utility, air box flooding
I was able to disconnect the muffler yesterday, actually verily easily. It ran really bad once disconnected, I'm assuming this is because there was no back pressure. I'll take a look at the timing belt and respond with what I find.
I don't know the amount of hours on the engine, I purchased it from a dealer used. I did notice the valves all look a bit different, on the amount I have to adjust them to come to .004. I'll post a picture. thanks for the feedback. I'm hoping its the muffler, since that would be the easiest to replace. |

Re: GXT 804 utility, air box flooding
I adjusted the valves yesterday to .004 and the intake valves looks like I had to adjust them more to get them to .004. Also I noticed gas\oil mixture on the top of the head after removing cover. I'm assuming that means its definitely a valve issue.
am I assuming correctly? |

Re: GXT 804 utility, air box flooding
I can't tell that good by looking down on them but from what I see they don't look bad.
Be better if you could get another angle looking across the head. You may be good on the valves. What you don't want to see are four or more threads on the intakes. That engine is clean |

Having valves out of adjustment should not cause a build up of oil in the cam/rocker area. How do you know you have gas in the oil? |
