The Briggs illustrated parts list for the Raptor 3, (5HP),shows a part number of 555076 for both the Int. and Ex. valves. Yet I have come across a Briggs motorsports valve spring with a part number of 555060 on the box. Was there a part number change from Raptor one to Raptor 3? Should'nt the stock springs be different for the exhaust and intake? I am in the process of refreshing what I believe to be an early raptor 1 for putt-ing around use on a Stellar mini, (Carb rebuild/valve job/94ss/.010 milled head), and would like to toss in some new springs, (cause their readily available, and a cheap peace of mind) while I got it apart? Appreciate any info on the springs, and this cheap refreshing project. Thanks.
