Just make a reference to where the needles were originally and you should be fine. Make sure that the oring seals are good on the needles.
Thank you for the info, but both the engine has the identical problems, we have checked either the leak or the needle oring but problem remain.
The engine runs pretty well before half tank of fuel but after that the bogging issue coming back than we checked the temperature is only 120 degree celcius which is the normal running temp. By the way we are running the engine on the 960 , we have already no clue ?? is it the engine problem or the clutch setting? But we use nova base engine on the 960 with no bogging issue with the same clutch setting +- on gap clearance.
Thank you and appreciated for all your help.. wondering if any people have the same issue with the IDM EVO3, Email to Daniel already but not yet reply
