Title: Jets...
Post by: njh1 on February 02, 2021, 05:04:43 AM

Hi all.

I have a Marine Quad from a 7.4 and it's going on my 5.0 GM. I think i need to re-jet but have no experience of how far to jump in jet size as a start. re-build kit will be ordered too.
I appreciate i might not have to re-jet at all but I am keen for anyone's experiences.

I believe the jet size is currently #68.

Thanks in advance.

Nick.

No problem, I can put together a rebuild kit with tuning parts for any part number.  Marine carbs are special units and not calibrated the same as automotive carburetors.  The good news is that there are only a couple of varieties and the major difference between them is very minor whether they were used on small block or big block engines.......
