It's a cowled engine and it has always been that way (say 6-8 months) andhas never had this problem. It has also alway been mounted upside down. I tried some new fuel yesterday, and that seemed a little better. I am going to try a new glow plug andsee how that goes. I know you said it shouldn't make a difference, but i\I'm clutching at straws now!I'll let you know. Thanks again
