Bought a Treysit Sirometer

After reading everything on here, and not being sure if my HMSK80 is set as high as it can be I finally decided to buy a tach.

The Treysit Sirometer seems to be liked by many, very affordable and very accurate. Not to mention, it has the same cool factor my Slacktube Manometer has, at least to me.

The last time I used the blower I noticed with the speed set a little higher it seemed much happier. It moved snow with more authority so I want to see where I'm actually set which is slower than that. I just didn't trust it so I backed off a little.

I'm betting I'm around 3000-3200 right now and it'll be nice to get a little more out of it.


Off topic :
For those that have never seen a slacktube I've attached some pictures. For some reason this simple device fascinates me. I used it for adjusting the manifold pressure on my boiler. It's dead accurate by nature and always will be.

Please, leave working on gas appliances up to the professionals.

manometer..

Not sure- But I had something like that once to synchronize the 4 carbs on a 1200 v-max motorcycle motor (mounted on a snowmobile of course)- It worked great.. but can't recall 'how' it worked anymore. It dialed in the carbs near perfect. Think something to do with flow of ventures or vacuum? Just know it had the same shape and had to get the two sides level I believe. sound right?

I used to fool around with MG's back in the day. They had twin SU carbs and seemed to me I had some kind of balance meter that had fluid in it. If I recall correctly it was placed over the venturi and you had to get them to read the same. Man has that been a lifetime ago.

I hear ya Joe.. I think it was 1986 or 87 on mine. I do remember the 'balance' you mentioned. a must for multiple carbs. Sounds like you had a very cool car! Don't we wish we had kept them from the day.

The Treysit Sirometer, also known as the "vibratach," is a great tool for any mechanic's toolbox. No outlets needed, no batteries, and very accurate. Used to be around $20...more now, I,m sure. I have one in my truck at all times. I have had the same two for years and they still work like a charm. When you first use one, you will smile. The guy who invented it should have been knighted! MH

I had at least a half dozen of those dang cars. I loved them. I called them the poor man's Jag. So much fun to drive and really a very simple straightforward car. I bought my last one around '88. Lost interest in it and let it go. Most of mine were from the 60's and early 70's.

If you have a multi meter with that can measure frequency you can use it to measure the rpm. Hz measurement x 60 = RPM

50hz = 3,000 55hz =3300 60hz = 3600rpm etc.

Take the positive probe and just lay it on the spark plug wire. If a clip on type just clip it over the spark plug wire.

I do,
However I don't think I feel comfortable doing this with my Fluke 179 which is the only meter I have with a frequency counter. Last time I looked these were selling for $300 so damaging it would really suck.

Curious what RPM everyone recommends setting the Tec HMSK80 to? I know it's spec'd to run at 3600 so I was planning on aiming for that.

In 1970 my friend had a late 60's Austin Healy Sprite, the same car as the MG Midget at that time. It was a blast to drive and ride in. Doing 55 felt like you were doing a heck of a lot faster. Your butt was inches from the ground. Sad to say it caught fire while waiting in line at a NJ motor vehicle inspection station .
