???----Where on the carburetor is the ---" other jet "----Picture please.=====Low speed is 1-1/2 out from seated.----High speed is 3/4 out.-----The motor will start / run with those settings.-----You MUST fine tune on the water!-----And how did this motor run for you last season ??

I just got it at an estate sale saturday.I have no clue.Its a nice looking motor.I have the foot off changing the impeller.I pressurized it and it held 12lbs for 30 minutes .The foot grease had no oil in it.The fuel lines were hard and I do not imagine it has run in a very long time.I poured atf in it right to start with and let it sit for one day.Compression is 112 on both cylinders and I have spark although I don't know if it's enough.The jet I was referring to is the top one .High and low are on the bottom .It might be air I'm not sure.I think this motor will run but I'm sure it probably needs carb cleaned at least
That's why I need the settings

I usually buy a factory omc manuel but 1965 was the earliest I found.

???----The upper needle is the slow speed mixture.-----The bottom is the high speed mixture.-----There is no " other jet" on this simple carburetor.----Take a look at the coils.----They are likely cracked as all of the original coils did.----Do a complete evaluation BEFORE spending beer tokens on a 60+ year old motor.

typical condition of coils mentionnned by racerone... your MUST pull the fly wheel and service the electrical. lots of utubes and folks to help out as your bring it back to life !
"The foot grease had no oil in it" no grease here refill with oil !!!

I ment to say the foot oil had no water in it

The carb looked good inside no varnish or crud .I got a kit anyway

 

[Crosbyman]

Kits are only good if the internal passages are 100% clean and should be your starting point Inspecting electrical is not an option to skip !

What is the best way to get the flywheel off.I know it usually requires a special tool.will screwdrivers and a maiiet work.Do you have to take the 4 screws off holding the plate on top of the flywheel
