<HTML>Hi - I have Honda Spree that starts fine and then dies after about 10-15 seconds. If I open the throttle it dies instantly. I have a good spark, the electric choke seems to be working ok (it gets warm after a while). The air filter is clean and oiled and I see no airleaks. I have dismantled and cleaned the carb and jets - all seems ok.
Now the interesting part - if I remove the choke assembly and stick my thumb over the hole it will start and idle quite nicely forever - still dies when I give it gas though. Also, if I remove the airhose and stick my hand over the intake it to feel for vacuum I get lots of gas and seems like plenty of suction. Not only that but when I reconnect the air filter the engine will then start and rev quite nicely for about 30 seconds before dying again - my guess is from all the gas in the manifold. If I look at the plug it seems a little wet but that's kind of understandable considering the hoops I'm going through. I'm at a loss as to whether this engine is getting too much gas or not enough.... Any ideas? Not enough compression maybe? Engine worn out? I'm baffled.
