the wt-813 carb has a hole in the rear of it thats not well covered by the papper gaskit or the ada gaskit, the hole im talking about is where the thottle shaft goes thru the carb and where the accelerator pump is operated from.
it looks like my zen sucked dust and sand thru the carb as there is dust and sand on the throttle shaft and the rear hole on the throttle shaft is full of sand and dirt and the throttle linkage is hard and gritty to move.
i know no sand has come thru the stock filter as its all clean,.
there is no sand on the front of the carb and no sand on the plastic airfilter stack
no sand on the insdie of the airfilter and airfilter set up and there was not sand on the carb gaskits.
ive gone right thru the engine, carb and airfilter set up, and it looks like to me the sand and dust has gone thru the carb, throttle shaft and the hole for the accelorator pump,
i do now rember reading this on the hbf forum over 9 months ago, and i brought a 813 carb yonks ago befor ready this and noticed this hole, but i gave it to a mate who was having carb issues and im sure you can fix or block the hole off and sand prove it, but i had forgotten all about this, and to be honest i didnt know what they where talking about.
but in my opinion for bashing the wt-813 carb is no good straight out of the box, but great for clean track onraod racing and in boats, but not good for bashing, with out modification.
i will be going back to the wt-668 carb as i know its good i don't have to mod it and reguarly perform maniance on it and have used them lots for many tanks, and in my mind i will not buy another wt-813 for bashing as i feel this is why my zen has failed, due to my lack of knowlage on the wt-813
guys i would think about modding the wt-813 carb or swapping it for the wt-688 carb if you mainly want to use it for off road and beach work, or just keep an eye on it, now this could be fixed with some good grease or a patch, mabe glueing some gaskit over the hole
all the zen 4 bolt owners with 813 carbs and all the boys runnign 813 carbs just be careful and every one considering a new 4 bolt, think about modding the carb or go with a 668 carb, as im sure im not the only one who has had or will have this problem ?
im not saying every one will has this problem, but its some thing to look out for, here are some pic,s on what im talking about, the hole isnt covered by the stock gaskits and is covered less by the ada manuifold gaskits, and this carb has excessive play in the throttle shaft for how much use it has
this is what im talking about, near where the screwing driver is
im not bagging the zen 4 bolts as they are a top motor by far, and im not bagging out the wt-813 carb, as its good it just has a weakness for bashing, and can be esy fixed with some silicone
