Diesel pressure washer hard to start

Tutster said:

Hi all I bought a lombardini diesel pressure washer like new as part payment off a job its great when it's running but getting it started either nearly rips you're arm off or you need a week off to get over it ? I've tried all the obvious tricks like  a fuel change starting with the trigger open etc but like I say it's a nightmare to start I heard something about a pin/key needs replacing something to do with the alignment in the crankshaft but god knows what I'm searching for on Google any help or advice would be much appreciated cheers all

Are you familiar with single cylinder diesel engine decompressor levers.

Normally you'd pull on the lever, while pulling on the recoil rope then let your finger of the lever to allow the crank stroke action

The thing to remember with diesels is the cylinder pressure is massive compared to petrol's. I believe the fuel timing is normally fixed in respect of crank position, so a damaged woodruff key could throw timing out.

Also the recoil starter should not pull your arm back in to the motor, so it might be worth replacing that?

I would be inclined to pay someone who knows about these engines to service it. The diesels are big, heavy, and noisy but they can be very good and last a long time but if it's not running right you will be wasting fuel, have low pressure and difficulties starting it.

No not a clue? I've done a bit of digging and the problem is pointing towards a broken shear key they word it as  a piece of soft metal designed to break off if something is untoward in the engine then basically you realign and slot a new key into the groove to reset the engine if that makes any sense lol.i think what I've read is pointing towards the engine is out of sync
