Ariens 932006 fix or replace

Hi,
Relatively new to the forum but not to auto and engine repair. The blower is in good shape except for motor issues. Hard starting, surging mostly. I have cleaned the original carb, replaced it with a $15 one with about the same results. Fuel system is clean with new hose and filter just before carb. New points, good spark, plug is clean. Haven't checked compression yet.

I recently put a 212cc Predator on a Craftsman/MTD 24" that had an LCT on it. Plug was oily haven't had a chance to take it apart yet. The new engine is working well.

The engine on the Ariens is a Techumseh HS50. Noticed it has a second pulley on the camshaft. Saw some threads here about dealing with that issue.

Now my question: Are there any lower cost engines that would have the external camshaft for mounting a pulley?
In my limited search it seems the supply is very limited or non-existent.

Thanks for any information I may receive.

Herb

I personally would only replace that engine with another twin shaft

If you can find another "Twin Shaft" engine. There are not many of those around anymore.
The shafts counter rotate being one is on the camshaft that is counter-driven/gear driven by the crankshaft. That way one pulley spins in the opposite direction as the other pulley does.
If you used a standard engine with just the one PTO pulley to drive both the wheel drive and auger drive, one of them would operate in reverse direction that what it is supposed to.
I.E. When you have it set to drive forward, and the machine moves backwards instead, or the snow auger would spin backwards but the blower would drive forwards.
You would have to use another twin shaft engine again, unless you do a lot of modifications to the machine to compensate for things spinning in the wrong direction.
The crankshaft had the heavier bearings on it because of the loads put on it, the camshafts never had heavy bearings for them to take a PTO load like the old engines had on them with twin PTO shafts. They used to wear out the camshafts drive gears and bearings in the case cover from the heavy load on them, plus sometimes the camshaft would break, it wasn't designed for a heavier PTO output load like the crankshaft was designed for.

Briggs and Tecumseh stopped making the twin shaft engines a very long time ago, back around the 80's.

I'll have to see that if you can find it.
The had gearbox set-ups for some of them. They might have come back out with it again on certain engines because Briggs got "World-Wide" with a lot of their products now. A lot of USA stuff stopped using the dual shaft output set up years ago. They could have been made for a foreign use but someone found them and is making them available here again.
I'll have to look at it if you can find it. Briggs was making all of their engines overseas and are in the process of bringing back manufacturing to the U.S. again.
I remember a lot of those dual shaft engines on older equipment and when they stopped making the parts for them, that left a lot of people and their equipment out of service.

That would probably work if the engagement clutch is not going to be a clearance problem.
The old engines had the shaft up higher than the main shaft due to the design so you would have to use a shorter belt on the new engine.
He would have to look at it closely and figure if it will fit and work before buying it, or buy it and see how it fits. If it works, great, if not, see if you can return it for a refund.
I'm just wondering because of how low that camshaft PTO is located if he is going to have a clearance problem with the belt tensioner idler pulley location.

You can take a single shaft Tech and replace the engine cover and camshaft with your old one to make it a dual shaft....or just look for a good dual shaft....or scrap the blower and get another one.

Cranman, yes as long as you can find one or the parts for one. They are getting hard to find now days.
