I have been hearing some hissing the last few weeks that I thought was my carb. I have always had a bit of fluctuation in RPM and always thought it was nature of the isky cam. This evening I sprayed some carb cleaner around in take while engine was warm and idle and sure enough. Around both of the drivers side Mummert runners its pulling in plenty of air. Its been about 6 months since the complete shop build so I dont know if I have a warranty for this. The bolts seem to be torqued down pretty good. Its not pulling in on the passenger side. What do you guys think? Are those gaskets redily available through Napa maybe? SOmething I could get on a Sat maybe and change out fairly quick? Should I use RV red on them too?
