yeah. I did just that Clermont. I put new RTV(RED sillicone gasket sealer) now There is no air leaks since I can hear swishing noises comming out of my carb. which means my motor is only getting air from the carb and no were else. Well the gasket sealer for the back plate sucks, it really doesnt seal. Oh yeah does anyone have a picture of the right way to put on the OWB. I am second guessing my self?! Clermont or ehoof or anybody could post pic showing right way to put on OWB for Vertex .18 stock volcano sv egine. Thx for all your help and advice.
