try some starter fluid  the revs should shoot up  make sure the wind doesnt carry it into the air box tho and give you a false diagnosis

no i don't think so  im going to try this today to make sure i don't have any leaks  

try a propane torch, unscrew the end of the burner and push a rubber hose on it, then you can guide the hose wherever you need it.

everything has an element of danger, some more so than others.
The propane should be fairly safe because it will only ignite if the fuel-air ratio is close to ideal.  Using it in the open should allow the excess to dissapate safely.

I doubt that, but I did have an idea for finding exhaust leaks a while back.  I've never tried it, though.

The idea was to introduce some Sea Foam into the combustion chamber.  Let it sit for about 10 minutes or so.  Then, start 'er up.

There will be lots of smoke.  You should be able to thus find any exhaust leaks visually.

If you try it, let us know how it works!

My daughter gets all bubbly too, but I wouldn't use that on even a cold engine.
