I just replaced one of my engines with a New 18HP B&S Vanguard v twin Model Number 356447 3079 G1 (serial Number 1804021104540). This goes on a Toro Greensmaster and the engine is connected to a hydraulic pump. I want to make sure the engine is running at proper high and low RPM. Does anyone know what this engine top RPM is supposed to be set from the factory? I was told 3600RPM (factory no load) which seems high. An idle of 1750 (red spring) or 1100 (white spring) is the idle speed. Out of the box it runs at 3575 high RPM and 1650 idle RPM (With a surge at low RPM).
What is the engine model 350447 type 1331-E1 code 04051311 supposed to run for high RPM? I thought I saw 2950 RPM in the service manual which is what I set it at. Why would these two engines have such a difference in high RPM if both of these numbers are correct for high RPM?
Also I see a change in oil requirements. My old manual states SAE 30Wt oil over 40 degrees change at 50 hrs and filter at 100. My new manual states oil change and filter at 100 hrs can use 5w-30 synthetic or 15w-50 B&S synthetic. Which is the best and does the new manual supersede the old manual for engine model 350447?
Thanks for all your help
