i have a nice pressure/vacuum pump but i dont have blockoff plates for anything bigger than a walbro HD series carb or a Stihl ms 660 exhaust hahaha. is there someplace i can buy the blockoff plates or should i just make them myself?

If your handy with tools, simple to make. Ya only need one for the exhaust, the intake is where you put air or vaccum into! I can tell ya a piece of PVC bushing internal threads, 1"X1/2" or 1/4" then a nipple screwed into that, or if larger carb 32+ you'll need a 1.25" bushing works great! Any local hardware should have it - bushing-

i see "carb blockoff" mentioned ?
thats where our leakdown testers connect...at the intake, then only the exhaust needs blocked off
most guys make an aluminum plate, < (stock pipe)
or just use the pipe flange < (aftermarket pipe) with a piece of intertube as a gasket behind it
i've also used one of these right in my exhaust flange........
