valve spring rate

#1
can anyone tell me what the oem spring rate is on a briggs ohv motor. i think its a 5.5. i could get some pics if needed i just dont have the shrouds(either that or i just cant find them). the reason i ask is when i tore that engine down i noticed that they were a higher rate than the springs in my clone so i swapped them.they work fine i just wanted to know what they were i couldnt find out myself for the life of me.

I measure one out of and older one here at the shop...5.5 hp and it was at 7.68 lbs compressed! But its a used engine! Hope this gives you a rough idea! Sorry it took so long! Oh and it was the exhaust side! The intake may be slightly less!
