Clockwise or anti?

Try a quarter turn 1 way or other

Is there a chance u have a grassmen sticker on it?

 

[Ryan3659]

No grassmen stickers I’m afraid I see this is a good forum to ask questions on

Go four turns anti clockwise! She be reet! Plenty of smoke, but no smoke no poke! Direct drive gearbox will handle it!

Relax! Try to give it a full service including refurb fuel pump first. Then if it’s still down on power look at tweaking pump. Simply giving it more fuel is masking a problem. Why do you think it’s down on power? Has it got worse?

Now Then..
I would always test it on a dynamometer before making any adjustments. I assume it runs freely and hasn't got any brake related issues holding it back??
You may make a small difference by adjusting the torque screen out a couple of flats but that may have already been done in the past. The real adjustment is inside the pump and requires a small special tool.
I've always used a dynamometer so one can put a figure on the before and after power settings.
A 3650 is already at the upper end of what's possible through the transmission, do you really want to take the risk??

 

[Ryan3659]

I plan on setting it up using the dyno I know the risks and I’m happy with that I’m just looking instructions on how to do it

What jobs is it doing that it's short on power?
Have the injectors been serviced recently?
