Re: AQ131c Carburator jets

It's only a 120 hp engine (2.3L), what size boat do you have.

When was the last full tuneup, including dwell and timing reset, and a compression test.
May also be the carb needs disassembled and cleaned.

Re: AQ131c Carburator jets

The boat is 19ft and can eventualy get upto full revs. i have replaced everything on the ignition side and rebuilt the carb. just trying to eliminate everything the boat was not previously owned by a mechanic. It feels like a carb setting or air leaks. My next test is a compresion test and maybe head off and valve lap! So if any one has a manual and can tell me the jet sizes it is one more thing to eliminate

Thanks for the help
Neil

You will probably have to get a hold of webber for the jet sizes as 131's originally came with a solex carb.
