As far as potato gun ignitions go, ive had no problems at all with the push button grill sparkers. The only caveat is to make sure you clean the contacts where the spark will jump every so often. (and thats only cuase i use hairspray, not clean burning propane) My guns shoot at least 90% of the tinme when i i have enough fuel in them. So if you are having problems with them experiment with different amounts of fuel and keep you bolts clean. If that doesnt work you may just have a bad ignitor
