is there any way to check the idle speed of the 48 b without a timing light. I could get one but I don't know how to use it. My problem is when I use my tractor ect. harrowing it just doesn't sound like it winds up like it should. almost like it's running at 3/4 throttle with the throttle lever wound out. any help will be appreciated.

Go to your nearest lawnmower dealer. Most sell a combo Tach/Hour meter it uses a watch battery. Mount it on your tractor and you will always have a tach when it is running and a hour meter displays when the engine is not running.

"B" Engine low Idle rpm = 475, Engine high idle rpm= 1850, "B" (BE Engine) Loaded rpm = 1400, "B" (CE Engine) = 1500 rpm. You will need a tachometer to check these. Checking the loaded rpm's is impossible without a dynamometer.

Since the engine speed would be hard to check with a hand-held tach- engage the pto and check there. 540 rpm should be reached at near wide open throttle.

I did some work on this a while back - a B engine will turn 2.5 rpm for every rpm the pto turns. The Owner's manual says that a pto rpm of 545 is reached at an engine speed of 1362 rpm. So, if you're trying for that 1500 rpm rated engine speed the pto speed should be 600 rpm.

McMaster-Carr has a nice hand-held tach you can buy for around $65. Not a bad investment if you need to set engine speed, idle speed, and/or check pto speeds on various tractors. You'll be suprised at how much some tractors' indicated pto speed (the mark on the engine tach) is off. Our 190XT with the hydraulic pto clutch was off a fair amount (slower than indicated).
