ya don't see many injections such as the birdcatchers etc...running gas...but i did do some research on doing the same thing when i ran a ron's (toilet bowl) a few years back...and the answer is yes it can be done (broad answer)......your ignition will be fine....if anything you would need something hotter for alcohol not gas.
