thankyou for your reply ,
Im very new to this engine and as far as i was aware the pump only has 2 postions on and off ,
i have downloaded the manual but it was'nt much help,
when the engine is upto speed and i throw the decompression lever it trys to brake my wrist ,
Ive watch many vids on youtube of this model of engine being started and they all seem to be able to keep turning the engine on compression ,
whith all my experince being with petrol engines in my mind it points to a stuck valve but that doesnt make sence when it turns ok with the decompression lever in its on postion

Engines / petter/lister PH1
« on: March 10, 2023, 10:21:26 AM »
Hi , I am new to this forum , I have recently bought myself a non running petter PH1 stationary engine which came off a small dumper truck , So far i've fitted a new exhaust and air filter , ive rebuilt the injector and bleeded the fuel system and im getting the clicking noise from the injector and getting a good spary from the nozzel , the engine is free and turning over no problem with the decompression lever in its on position which allows me to crank the engine upto speed , when i move the decompression lever to the off postion the engine compression becomes to high to keep turning the engine by hand and the engine trys to backfire and run backwards , when the engine backfires i get a small puff of smoke from the inlet manifold , can anyone give me some advice on what im doing wrong of what could be wrong with the engine . chris
