carb trouble???

[rcbe]

have you tried running with gas cap loose? if cap vent is plugged, engine will eventually starve for fuel.

Yes...thanks...but tried that...same problem.
I am now thinking contaminated fuel..or a bad SAM.
Ignition control module.
Any one with experience of failing electronics ?

Gotta be a carb problem.... ordered a rebuild kit today....which is just
gaskets, float needle , and 4 top screws...good thing ...
(I lost one in the intake valley ) .... and a new idle screw and spring....
pretty lame rebuild kit actually.
The things I Do know are :
1. Fuel IS getting to carb
2. Fuel is NOT contaminated
3. Carb runs lean , and stalls
Things I don't know :
1. Is ignition cutting out ?
Spark is there when tested
2. Is SAM at fault here ?
3. Can coils go bad under load ?
Some one out there must have had a dupe problem like mine....
wish I could find them

i kept getting trash in mine...i strain my gas out of the can now....i tried to clean out the tank but its a difficult shape to clean out......someone else was saying that it happens a lot to these carbs but i dont know

Is your tractor actually runable now ?
Mine is not.... but thank God we are in a dry spell and grass is not growing.
Hope to have this problem licked by the weekend.
I am wondering if there is a carb out there that can be substituted
for this Keihin ?

mine is runnable as of when i parked it. I had finally finishe the lawn. I started it to move it yesterday and it was fine, but didnt move far

 

[GTSRider]

Sounds like mine WAS....now it will barely run...
can't wait to put the rebuild kit in ...later this week.
If that don't do it.... may be time to torch it !

 

[Donsyl]

let me know how it works with the carb kit

 

[GTSRider]

Got it today... will try to install tomorrow.
Not much to it .... all rubber gaskets and seals , and it looks like
and adjustable needle .... I guess I may have to drill out plugs to side ports ?
Anyone know ?
