Well I blew up the engine in my free to me Toro ccr 3650,I am more or less curious, if it's worth me replacing the engine?

My wife says no. But I found a short block on ebay for $ 108. But I don't really know small engines.

Put it on craigslist it will sell. Go buy something with more huevos!
I don't think I need anything with more cahones. My driveway is 60ft, and I do my sidewalk. It did that just fine, I was doing the neighbors driveway when it gave up the ghost.

I may just off this one, and buy a newer one. I just feel bad because my aunt gave it to me and I just picked it up on Saturday lol. But it is quite old.

If you want the same model, look on your local CL. It's a popular model and should be easy to find. Make one good one out of two.

Yeah I found another for double what the short block would cost, or I found a 7hp snow commander. The engine looks roughly the same per parts diagrams. And it's $75

The 3650 is the best "beast" single stage you can get! I would put them up against most 6.5hp 2 stages, on a hard surface, in snow up to 5". It has a 6.5hp 2 stroke and will get after it on hard surfaces. Tweaking them a bit helps too. :whistle:(y)
To bad the OP isn't closer to me, I have a real nice electric start 3650. ;)

How blown up is it? Is it 2 stroke? Maybe you just burned up the piston?

Give it a quick ball hone and throw in a new piston and rings.

Haven't torn into it yet. A new short block is $108. A piston is $100. If I do fix it, I'll be doing the short block. Currently, the engine rotates a little and stops. So I am betting I spun a bearing and something else.

You prob have a piston ring sticking into the intake or exhaust port. You will never know if you dont break out the tools though.
^^^ pull the exhaust and do a peek - a - boo
I am an adventurer. Electric start? hell ya! I'd tear into it and fix it - if the chassis and the rest of the machine is A+.
Are ya think'n maybe it got straight gas with no oil? :unsure:(n)

The gas w/o oil is possible, yes. I could not see what was in the tank, or know what my aunt ran through it before I put in the 50:1 that I had here for my echo trimmer. So if it happened before I got it, it was already on its deathbed. Me running it for a few hrs yesterday worked it too hard and killed it.

If you wait until summer there will be lots of cheap options at garage sales. I bought a CCR3650 8 years ago for $10 and invested in new paddles---worked great. Last summer I came across a newer version (same 2-stroke engine) for $30. It is slightly wider, and 10 years newer, so I sold my CCR3650 for $150 just before winter. Now is not the time to get any deal on a snowblower or parts.

It appears this snow blower uses an engine in an unusual configuration. I doubt you could throw in a Harbor Freight or other engine without major modifications if even possible at all.

there are plenty of lawn mower / small engine salvage yards. I found what I needed thru one of them once when I was in a situation like you are. But I don't know if it would be worth it because there is a Toro 3650 with lite use for sale in Bay City for $150 on CL. Offer $100 see what happens. Good Luck.

I question the "blown up" statement also. Unless the rod decided to leave the block (no 2 stroke oil) I would agree. Hone, new piston and rings.

what is a little ventilation in an engine. Stick a big bandaid on it and put it on the shelf as an ornament. :)

Make sure that the governor is adjusted and working properly.

I would not call it "unusual". Certainly different, but I will bet Toro made over a million snow throwers with similar engines mounted the same way !
It is unusual compared to the vast majority of small engines. It is a good snow blower, but you just can't throw any old engine on it if the engine dies. My father gets about 20 years out of this style of Toro snow blower before it starts having problems and he buys a new one. He just got his third one for this winter. He bought the first in 1981.

Yeah, this thing is great when it functioned. I should have the new engine next week. I have it 90% torn apart. I need to still remove the fuel tank and the lower mount bolt(s), that way I can take apart the flywheel and engine prepping for the new one.

If he didn't F with the governor they just dont go out of adjustment on their own. My bet is he ran it low or out of oil. You wouldn't believe how many machines I get in here with little to no oil in them.

it is for that reason this household is instructed to check oil before running any machine. One time I offered to change the oil on a friends mower that was knocking a bit and needed to sharpen the blade. Zero oil in it. I had to fill it, run it and drain it twice just to get rid of most of the sludge in it. Still ran for years - amazing.

Gentlemen, a Toro CCR 3650 is a 2 cycle, so no oil level to check.
Of course the mix has to be correct and governor adjustment is easy to check.

It is a 2-stroke, no oil to check. I am betting my Aunt or one of my cousins ran it with regular gas, not 50:1 and fubar'd it before I got it. Me running it for the extended period of time was the nail in the coffin. I ran it for 3-4hrs total yesterday, and it was the 1st time that I had run it. I have a new short block on order, so I am not too worried about it. I have the old engine almost out. I do need a new belt from the looks of it.

And I did not nor will I screw with the gov. The carb is getting unbolted, the starter is getting unbolted, and the flywheel is getting unbolted and all bolted back onto the new engine. not screwing with anything simply replacing the short block and running it.

I worked at a place with lots of trucks, tractors, and other power equipment. Most everything was old and well used. The gas pumps had a big sign to check oil at every fill up.

They had an old McCormick Farmall tractor. The oil pressure gauge was reading zero and we all assumed it was broken due to the age of the tractor. It turns out the driver of the tractor had never checked the oil and when someone finally checked there was no oil on the dip stick! Oil was put in the engine and suddenly the oil pressure gauge was actually showing pressure. The tractor didn't seem to suffer any ill effects from being run for weeks with no oil pressure. It could have been the end of that tractor.

If you don't mind, how much did that cost ?

Last time I changed the paddles I installed SS fasteners.
$134 w/ new head gasket, carb gasket and exhaust gasket.

Surprised me but the crank cleaned up. The odd thing to me is there was needle bearings in the case. It's something else that they use ball bearings for the main bearings.

Many small engines use an aluminum rod that rides directly on the steel crank. If the rod lets go the crank can be cleaned up. The problem is replacement rods do not come undersized.
