I searched a bit and came up with one or two answers, but was wondering what everyone is using for the rubber to do their vacuum/pressure tests? Will the inner tube from a bike work? I saw someone was using a motorcross innertube, but I was kinda hoping someone had an idea where I can get rubber that comes flat to begin with. I will see if i can get an old split rim inner tube from work monday, but in the mean time anyone have any suggestions maybe easily sourced from HD, lowes, plumbing supply or the like?

The P51 is done and a monster. I fitted it with a 28" NOS bar and 3/8 skip. I got it in some 22" red oak the other day and it rips.
Video soon. In answer to the second part of your question, I am having fuel issues with a poulan 3700 in craftsman colors that I have been tinkering with and I think it needs seals. I was using some hard(er) rubber I had on hand but it is leaking around the rim, and I cant get an accurate reading on my tester. I was looking for something a bit softer that would form a better seal and eliminate any air leaks around the intake where I blocked it off, and around the exhaust where I am pulling vac/pressure from.
Have any of those rubber shields off of a old clutch cover?? New one would likely work best but I bet they would do the job. Loosen the carb/muffler bolts, slide it in and tighten the bolts back down.

Good to hear the P51 rips. Somebody here was using some sort of duct tape from the local hardware store for pressure/vac tests, I've got the name here somewhere if your interested. I've got some spare 3700 parts lying around here if you end up needing some. Is the duckbill valve in the gas tank in good shape?

For ones I expect to do this same model again, a plate and rubber gasket.
For models I hope not to see again, Gorilla tape, then put the muffler back on.

Just a heads up, a 3700 really needs the impulse hole for the oiler plugged off it you really want a accurate vac test. I have a old pump cover I use for blocking them off.
I use a bike inner tube for my block offs.
Duck bill, fuel and vent lines, filter, plug, carb kit, etc are brand new. No problem on the parts, I have enough for this project, just probably have to order seals, once I determine that they are in fact no good. Thanks for the offer. I still owe you one from the Pioneer

I use thorn proof bicycle tube, it's thicker rubber than a standard tube.

.....so thats what they put that rubber on there for.......it allows us to pressure test our crankcase's!!
you can also buy the stops from husky in there tool line a set is just a few bucks i have several sets that i trim and make fit diffrent saws and then lable them and keep them for that model or others that it will work in that to me seems to be the best and easiest way if you have some time to order them from your nearest dealer i would say go for it and try that out
