Hi leshby, I have done some research for you, we do need you, as Joe has said, to post the exact model number of your machine and a close-up pic of the engine and please include the engine serial numbers.
As some background, all petrol SP Tools pressure washers use the Torini engine. The petrol range of pressure washers includes the SPW1300P, SWP1500P, SPW2500P, SPW3600P and the SPW4500P. Here are some specs:
Engine:6.5hp OHV Scorpion

Max Pressure:2500psi
Flow:480L/hr
Speed:3600rpm
Pump:Brass axial B2200
Hose:8m
Lance:Variable fan
Weight:40kg
Here's a small pic....Is this the same as yours?
