I was having issues with my 8KW starting. Not starting, backfiring and such. After reading this tread I checked and low and behold, the bellows(?) (Air intake to the, I guess, mixing chamber ?) was off at one end, looks in good condition just the clamps would not hold it in place. I took off the factory clamps and installed gear clamps instead. I will check tomorrow, once the set has cooled down to see if it is any better (Fingers crossed). If it does, Thank you, thank you, thank you !!
Nope still a problem.
