Ya or next week. We all have things to do!
Might be a line leak, pump, carb, but that little test will help to narrow it down at least to fuel. You can make a squirt bottle with a plastic coke bottle and drilling a little hole in the cap for a one time use (don't keep something like that in the shop if a little kid sees it and thinks its coke, throw it away)
Be careful though, fuel and fire
.
Best of luck!
