backfired

So here is what happened guys....today was the 2015 maiden voyage. happened quick but hooked up and went to the lake. Quick started it in the driveway to make sure it would fire. No sweat, fired right over. Went to the lake and sat forever in line waiting on a bunch of ding dong's figuring out how to launch the boat all the while DNR staring at everyone through binoculars and checking every friggin boat approaching the dock. So renee backed me in and I hit the key and I knew I was screwed right away. No fire. Rolled over but no go. Couldn't smell fuel or anything. Had her go back to the parking lot, kept pumping the hell out of it and then could see and smell fuel. Wind kept me from smelling it on the lake. While looking at the carb I noticed a wire that came out of the BATT pin on the DUI ignition. Fixed that crimp and literally BOOM! Huge backfire. Renee said flames shot out the flame arrester 6-8"! Scared the hell out of the kids...I mean crying! So I had a big backfire....but it started and ran fine after that. Relaunched the boat and it ran fine. Had one stumble at idle while kids swapped driving but never again. Drove it for a 1.5 hours.

Big question is since I had a big backfire due to me pumping the hell out of the throttle trying to get fuel up and then putting a spark to it, did I do some damage to the Holley? They have a blow off valve right but do I need to go through something after this happens?? Want to pick your brains but didn't know if I need to get in touch with Holley.

Thanks in advance!

Thanks Joe. I was thinking last night that I forgot to mention that the Holley was new 3-4 years ago from Jody. I wasn't sure when Holley started putting that feature on the carb but now I know! Thanks!

Well, we will just carry on as normal then. Boat sure ran good. Gonna throw in some new plugs this year just because. Been a few seasons. What do you recommend. Still the old Autolite 764's? Is there a improvement to look into with the DUI?

Have a good one Hoss!
