[QUOTE="steve.emma, post: 1224991, member: 36039"] checking for air leaks can be tricky depending on where the leaks coming from. a manifold leak is often fairly easy to see with a torch as you can move the carb slightly and see if any cracks in the rubber open up etc.. crank seal leaks can be checked visually on the l/h side if you remove the flywheel and then the stator assembly. a leaking seal normally has some oil residue around it (which is why the r/h seal is harder to check as it lives in the gearbox and requires more work to actually look at it..) base gasket and case gasket leaks can sometimes be picked up by just looking, but the best way to check for ANY leaks is to carry out a leakdown test of the crankcase using low pressure compressed air. this takes a wee bit of doing and unless you are fairly competent then i reckon its a job best left to a workshop. however check the basics first as it may be just a simple thing.
