Pete Jackson Mechanical Injection setup for a big block Chevy. It came off a running engine and has just been sitting for years. The setup it pretty damn complete. I was going to run it, but decided to stick with the tunnel ram setup.

The first time I took it out it had a bad backfiring problem at idle and on throttle but only on the passenger side, messed around with the carb and distributor while driving with no luck, loosened a couple rockers and it stopped popping on idle but still on throttle.
Re adjusted all the roller rockers on the passenger side while running on trailer and all popping stopped. Got it into the water and runs great up till 2500rpm and then goes back to backfiring
Any ideas where to look? Figured somewhere in the heads maybe sticky lifter or bad springs?

These guys are my go-to for carbs...let them know you heard about it from SoCal Jet Boats.

You don’t waste any time! Good job. Hopefully you’ll see and feel quite an improvement.

Thanks man yea i really hope so it already got up and boogied before the motor and pump were built, just the piece of mind knowing theyre both fresh and done right will be worth it.

Wasnt too hard keeping my fingers crossed there is no leaks testing it out tomorrow at the lake.
