"I was running to the launch yesterday aboat 3800rpms and 3 quick pops came out the carb and lost power ...

I throttled down and it shut off ....

sat there aboat 2 min. scratching my head and decided to start it up.... it ran good the rest of the way in aboat 2000rpms.

I was hoping it was gas so I changed the fuel filter and dumped the oil also..... added some dry gas... Cleaned the arrester, carb and intake up with carb. cleaner and brake cleaner....

going back out in a couple of days just thought I would run it by you guys to see if ther was more to do

thx.

"Sticky intake valve I bet.
I had this on occasion with a 5.0 a few years back.
Scares the cr@p out of you doesn't it?

Try some seafoam or upper cyl lube in the gas. Or some ATF if all else fails.

Use BG 44K in fuel. stuff work

Use BG 44K in fuel. stuff works awesome!
Also try trans fluid through carb while reving to
1500rpm on muffs.(don't polute lake) Add fluid slowly and hold your breath as it will smoke good.
This will clean carbon deposits from top end
and help clean buildup on valve stems and above the seats.
