Last night while at walmart I noticed they had an ignition for a barbecue. It was not the old style piezoelectric but used a small battery. I got thinking about it and would have gone back today with $17 and bought it except I am now trapped here with the new snow. Has any one messed with one of these? I would guess it maybe a continuous spark with the push of button. It looks to have a molded spark coil and could probably be modified to work with a small slow speed engine. I wish I had bought it or at least got the manufacturers name so I could look it up on the internet. It said it came with 3 spark tips for multiple burners and assume they would all fire at the same time. I am thinking a larger battery with less voltage and a micro switch and we would have a complete ignition system. john
