hi i have a question what are the part numbers for the stihl adapters that test the crank case pressure. i dont want to buy the whole kit for 475 bucks.
 
Exhaust sealing plate 0000 855 8106 (89¢ at the dealer)
Carb Flange 1128 850 4200 (Can't find the receipt but I believe less than $20)

These 2 tools will test a large majority of the stihl series. I also use the MityVac 8500 pump as it has pressure and vacuum at the flip of a switch.
 
stihl 028 stihl 031 stihl 041 the first pic is the 041 the other two pics are of the 028.

Well the way to do those would be make not to thick metal plates for the exhaust ports drill holes to bolt on ,use an inner tube from a bike or what ever to seal as a gasket between. As for the intake you buy another one then take the old one fill up the top area with silicone careful not to get the mounting area at the bottom gooped up or you will not be able to seal and just put that on and it will seal nicely. Then you need a miti vac 8500 tester that will do vac and pressure.
 
ok thanks. now when i put pressure on the 041 crankcase tube air just flows into the crankcase is that normal.
 
i mean the the tube that goes from the crankcase to the carburater. i push air into the crankcase but it doesnt hold pressure.

Well get a spray bottle with soapy water keep pushing air as you spray and look for the leak it could be the block off plates the seals the base gasket or the plug is the flywheel off and the clutch so you can see the seals? Do you have it blocked at the intake and exhaust already?
 
yeh i do mean the impulse tube and those pics i took were just my extra saws i have lying around. no i didnt make a pressure kit yet
 
Here is a couple of pics of some of the Stihl block off tools, some of them have a nipple or screw that plugs up the impulse line
at the same time. You could easily make something real close with some silicone and some old junk carb bodies.DSCN6529.JPG
