How are you measuring RPM?
Are you guys using a timing light to set your idle?
Jay was bogging down today while mowing - the first time I've had him out, and I was wondering if he was even idling/running fast enough, cause I thought he'd chew right through the stuff I was goin' over... Then I started wondering how I'd be able to tell if he was running at 1800 RPM or not?

RPMs
One method is to measure the RPMs off the running PTO since this turns at the speed of the engine. They make a nifty little hand held unit that you put up against the PTO. I hope someone else chimes in here as to where to get one.

I have a Swiss made unit that has an internal clock. When the shaft is engaged and the start button pushed... it runs for exactly 3 seconds. It counts the revolutions during that interval and automatically does the calculation. Drive your Cub over here and we'll check it!

Unfortunately, I cannot afford a wonderful piece of precision craftmanship that George is the proud owner of, soooo, I use a made in Taiwan Sunpro Dwell/Tachometer. One lead to the ground side of the mag and the other lead to the positive side of the coil. Works good, seems reasonably accurate and for $19.95 Cdn, affordable too!
George that really is a beautiful peice. A work of art really!

Rudi,
It really is a fine instrument. I got it the only way a tightwad like me can... at a garage sale. Some days we win one!

Good on you I try to get my wife to go to garage sales with me, but not too much luck there, and I really don't like going by myself. I think I just may have to take in a few over the next few weeks.... might get lucky and find something useful

I have never seen a real tachometer. I thought they were a old wives tale. I am very jealous. Looks great.mltiema wrote:IH made a tachometer available as an optional extra cost item but they are hard to find today.

If it doesn't move and it should, use WD-40. If it moves and shouldn't, use duct tape.

That is what I was going to ask. If it is cable driven, what is it driven off of? My Ford 5000 has a the proof meter driven off of the back of the generator. Lucas (Prince Of Darkness) electrical system.

Tach...
George,
After trying to get me to bring the Cub over there for "inspection", I thought you were going to say you acquired your HandHeld Tach the only way you could - by convincing someone to bring it over for "inspection"...
