Is there a difference between a leakdown test and a pressure test ??

Dumb question I know, but trying to work out what I need to buy.....

Leak down is tested through the spark plug and pressure is tested through the pulse line ?

On a two stroke you are testing the whole engine for air leaks, you need to blank off all openings. Mostly the intake and exhaust but also the decomp valve should be removed and blocked with a proper plug. The saws with an impulse line can utilize this line to pull vac on. If the saw does not have an impulse then a fitting needs to be made/ found that fits into the sparkplug hole and the vac pulled from there. If a two stroke fails the vac test then we use low pressure air, under 10 lbs, to find the leak.The air can bbe supplied to the engine via the impulse hose or the sparkplug fitting.
Leak down is different, its pressure applied to the fourstroke cylinder to check for things like ring condition, a bad head gasket, burnt or worn valves or a crack in the head or cylinder.
