Harbor Freight #97964 79.5cc 2.5HP - now what?

[Quenton Guenther]

Hi skunky,

HF motor turns counter-clockwise and doesn't need to be turned around. Several have used the Q-Matic drive system on the HF motor [we designed it to fit many, many, many motors] and it works 100% on the HF motor.

We can upgrade our drive [in a matter of minutes] to bolt-on to the HF motor, and "dial in" the correct ratios to set the right clutch stall speed via special drive pulleys.

The Q-Matic ratios are almost un-limited, and are easily changed for individual needs during production [to save you $$$$].

If you need more information, contact any EZM dealer or either main office [East coast... NC, West coast..... CA]

Have fun,

how well will the Q-Matic work on a tandem rear mounted system

 

[Quenton Guenther]

Hi Skunky,

Because of design the Q-Matic can be rotated to fit many applications. The bearing supports can even be rotated to create clearance options if needed.

Have fun,

When can I buy one? Your website doesn't say anything about it. I'm interested in the part you show mounted to the motor in the pic you posted - I have everything else I need to make it work.

Contact an authorized dealer in your state. If no authorized dealer in your state or they don't have the Q-Matic in stock we can ship direct to speed up the process for you.

You are welcome to contact me directly if it will help.

does the HF have a centrifugal clutch, or will it just stall when you take your hand off the throtle?

Hi snowbanana,

The HF 79 CC motor doesn't come with a clutch.

The Q-Matic drive system has a built in cent. clutch. The Q-matic drive doesn't mount the clutch on the motor shaft because the extra weight acts like a flywheel and slows the rate at which the motor accelerates. The Q-Matic suspends the Max Torque between 2 very heavy-duty bearings and only part of the clutch spins until it reaches engagement speed.

Have fun,

It doesn't come with one. This one will fit it:http://www.mfgsupply.com/m/c/4-458.html?id=eIQ5C35R

A more expensive way to go is with a 78mm centrifugal clutch. This allows you a selection of gear boxes (reduction gears) Stanton and Dax usually have these but at a bit more cost than the larger max torque clutch.

The HF 79cc engine does not need as much gear reduction as many of the smaller engines do. This should work a Torque Converter Backplate & Jackshaft Here:

It's the 5th item listed.
Hope this helps.

with the clutches and stuff I still need a way to make the engine turn clockwise...right. How would I solve that proplem?
