hi I have a HY 30cc engine and I need a new gasket part number 25045 it is call a air inlet pad and was wondering does the cy gaskets fit the HY engines as they don't have any listed gaskets for HY
 
you sure that is it the bottom and are a bit curved for it I think how did you come up with that one
 
its an insulator gasket all the small bore motors use the same one...i have 4 diff motors sitting here ranging from 23-30.5 cc and they all have the same gasket....the only motor i have that uses a diff one is the cy42cc
 
They'll work. I've never used the heavy duty gaskets for the intake or exhaust, but I've used the heavy duty head gasket and it blew out just like the factory gasket. I'd stick with the Zen/CY kit. It's cheaper. I'd buy at least 2 or 3 sets, as well. It'll save you money on shipping and you'll have plenty of spares.

It just blew out. I torqued the head bolts to spec, so that wasn't the issue. I've had good luck with the blue paper gasket with the head bolts torqued properly.

I have to and always torque all my engine fasteners to spec. Some that have so much trouble with the 2 bolt engines blowing gaskets wonder if a lot of it has to do with improper torque?
