I bought a brand-new STIHL MS 290 Farm Boss with a 4 year warranty. It is hard to start cold. Once I do get it running it restarts the first pull.
When trying to start it I first set it to full choke and have to pull it countless of times before it will fire off and then die. Then If I set it to the high idle position it might start right up and start to rev high and then quickly die as if it runs out of fuel. Then by the time I try starting it in the normal operating position, after my arm is wore out, it will finally start and die time after time. Once it starts and idles it has a problem of hesitation for a little while before it will rev up. Once it finally can rev then it seems to do just fine - until I let it sit for a while and then the problem starts all over again.
The Dealer told me it was most likely flooding and tells me to pull the plug and blow air through it until all the excess fuel clears the chamber, but there is no fuel coming out the exhaust and I has blown air through it anyway and there is no fuel spewing from the muffler. I can not see this as a flooding problem like the dealer says, it seems to me that it is starving for fuel.
So an even worse problem begins, as for the next 4 years if I open it up to diagnose it right myself I void the warranty. I am wondering if any one knows why a STIHL MS 290 Farm Boss carburetor systems would be drained of fuel (or take in excessive air) after sitting-up a while so that I can tell the dealer to look into it and fix it instead of just giving me :censored: advice.
