GX35 gas issue

[jucasan]

How can I check the fuel line is properly working?
Seems like there is no gas in the combustion chamber.

Pump the air purge bulb on the bottom of the carburetor a few times and see if there is gas flowing back to the tank in the clear return line.

There is gas in the bulb and there is gas flowing back to the tank. But still wonder if the mix air/gas make it to the combustion chamber.

Whats the motor doing to make you think that OP? How many miles on it aprox? Is the air filter dirty? Have you messed with any adjustments?

 

[jucasan]

Is not too old, 1-1/2 y maybe. Filter is clean, new spark plug.
With the throttle fully open the engine start for a few sec, then stops. that make me wonder that probably there is no enough air/gas going to the combustion chamber. When I try to start the engine with the choke on, don't see any fuel in the spark plug.

I'll assume spark isn't your issue because you say its starts and REVs up then dies. Check your fuel hoses for cracks, next I would make sure your carb bolts are tight. If that doesn't do it the carb would be my next look. Could be trash in there or the diaphram has a problem. Are you sure its not under warranty? Soobies carry a 3 year warranty, not sure what a honda carries. The gas cap should be venting properly too. Just some ideas others will chime in.

You shouldn't see gas on the plug, if its wet its flooded.Its probably a bad diaphragm and no its not covered under warrenty as its a wear item and the engine warrenty is voided the minute it goes on a bike.

I've never had to deal much with this type of issue, but it definitely sounds like it has something to do with the carb. If it gets really frustrating for you might be good to keep in mind that you can have a brand new carb delivered and still have change from $50.

This carburetor offered on eBay might work on a Honda GX35, but it is not a genuine replacement part.

The issue the OP posted is almost certainly a carburetor issue though. Because of the fuel we have to use, sitting for even a short time can cause damage to the delicate rubber parts in these carburetors.

A correction to the parts source I listed there:
It is mowers4u.com, NOT mower4u.com
