wow, thanks fer the laffs.
ok leak checking, 2stroke? seal off 2 of the 3 holes,intake , exhaust then build or buy a device to add air pressure (5lbs more will produce leaks you dont want this) through the spark plug hole. with piston at bottom dead center it should hold pressure thus no leak to outside. THEN find a way to create a vaccum to -5lbs, again no more or bad things may happen. if these both hold pressure , not for ever but a while, you probably have no air leak. this does not rule out carb, intake, exhaust pipe. i use a medical device thats for atomizing a liquid an its inhaled. it pumps air and when something pumps air it must suck air, opened it up attached hose to the sucking end, waalaa vaccum pump, 2 in 1. YES an 0 ring tween carb an intake is GOOD. also anaerobic gasket maker , check orielys "may be behind counter" this does not harden unless hardener is added, DONT ADD, spread this on intake,oring, carb mating surfaces assemble. it will wipe off months later. it seals well. i paid 15$, worth it.
WATER?? to leak check? um water ever so slowly introduced into a reved up motor will remove carbon. to much will remove crank. that would be bad,
leak checking a running motor can be done with carb cleaner, braklean, wd40 and best choice is propane using a hose attached to torch nozzle. overspray around aircleaner and youll think you found it!! an replace gasket for nothing. beware overspray into air cleaner. oh, sprays may create fire on hot motors, fire is bad, dont burn your parents house down.
now go create your very own leak checker you little monsters.
