Smowblower with Tecumseh 8 HP Won't Idle Without Choke

Hi

I am having the same problem as explained in the following thread:

http://www.doityourself.com/forum/ou...eh-engine.html
I checked and cleaned the small opening on the drain plug as explained in the above thread. I also removed the jet and checked it for any blockage but the motor only runs when half choked and still surges at that. Is there anything that I overlooked? The carb bowl and jet seemed quite clean.
Anyone's help would be much appreciated.

It's normally just a matter of cleaning the carburetor. There are some small apertures on that drain nut that need to be cleaned. Sometimes with varnish deposits using Sea Foam from an auto parts store takes care of it and you won't have to do an extensive hand cleaning of everything. I use it a lot as first choice.

If you have deposits of dirt those need a different level of cleaning, but if your filters have been in place and there isn't rust in the tank or fuel system to contaminate it, the problem is normally fuel varnish from old fuel.

An additive will take care of that.

Forest,

Take the entire carburetor off. You need to clean the entire carb. SOmetimes it may only be the jet but there are other holes in that carb that need a cleaning. The carb works by hi and low pressure. The gas is sucked up from the bowl into the throat of the carb and into the engine. If there is any blockage on the way up the carb from the bowl in any way, you will have a starving problems for gasoline. Revving is a sign of lack of gasoline. Also make sure that the float is working correctly. Must have plenty of gas in the bowl.
A tecumseh rebuild kit once you have taken it apart and cleaned it all is about 10 bucks off the net.
