i just put a propane meter on my combustion cannon and now it won't fire. it use to fire ever time. i thought maybe there wasn't enough air?

you're putting too much propane in, try adjusting your pressure in your fuel meter, make sure you correctly measured your chamber using http://www.burntlatke.com/ft_live.html and you have the right sized meter

also are you venting your chamber enough after each shot? install a chamber fan to increase the chance of the mix igniting, and also to quickly vent the chamber

thankyou. what does the fuel mixture mean. i got everything else

fuel mixture is the percent of fuel in the chamber, you want 4.03% for a normal combustion cannon
