Hi all,

Well after a bit of a break in the repair of my $50 6 hp Johno, I have it fully assembled and with a fully rebuilt carby. New coils, and new plug leads, new fuel pump and fuel hoses and new starter rope.
My question to anyone who would care to answer is the following.

Since I pulled the carby apart right down to the last separate component, cleaned and or replaced each part, correctly assembled it and now it sits all nice and new waiting to run.

What adjustment, or how many turns out from fully wound in should the Slow idle speed needle be?

Cheers

According to Joe Reeves' instructions elsewhere

1½ turns. Then start the engine, reduce the rpm to the minimum possible. Progressively turn the screw in 1/8 turn at a time Keep reducing the rpm if it speeds up. Eventually you will reach a point where it wants to stall or spits back Back the screw out 1/4 turn. Within that 1/4 turn you will find the smoothest setting.

Now fit the knob in the middle of its adjustment range and reset the idle speed

( BTW you do know about the idle speed adjustment on the end of the tiller? Many don't understand this

Never had to renew any of the parts you have renewed on my '84 6hp ....... what ever was wrong with them all,
All I have ever had to do is replace the pump impeller periodically ...... sort out the pesky grommet at the top of the water tube several times and replace the gear-case seals 2 or 3 times
Did away with the grommet eventually and made up a system of nylon spacers and O rings

PS. you will find a (Seloc) manual that covers the engine on the Boatinfo website ....... Sorry MarineEngine will not allow me to post a link

Vics,

Cheers for the info mate, now I have 'base' point to start from it will make it a bit easier.

Yes, I'm aware of the tiller Idle control and I have wound that out so that it has no effect. Once I have the Slow Idle adjustment to it's sweet spot I will be able to use the Tiller control for any further adjustment.

Funnily enough, the only parts that needed replacement were the carby float and the pull start rope. The rest were additions I decided to do whilst I had it out of service.

I used to have a 7 and 1/2 hp Johno way back in the early 70s that pushed around a 12ft tinny day in day out without so much as a hiccup, I bet I could've fed it on cough syrup and it would've still run, best little outboard ever and started 99.99% of the time with the first pull, if not the 2nd. Sold it and the boat to a neighbour and within 2 months his teenage kids had wrecked the motor and holed the boat on oyster racks. They failed to wonder why it started to slow down and was getting smokey one day when fishing, instead they just kept the throttle wide open and in the end it just seized. When their dad pulled it onto the boat trailer he found a plastic shopping bag wrapped around the lower leg and it was blocking the water inlet. Dumb ass kids, que sera sera.

Cheers and thanks
