    • Hard to start & has a severe rattle when first started - every time. Updated 8/19/23
Size: 173cc
Used it to replace a Honda gcv lawn mower engine. Original review was 3 stars upgraded to 4. Had many issues with this engine. Primarily with the blade bolt coming loose repeatedly. Finally used thread locker before always used anti seize on mower shaft bolts. Not sure of the root cause but never had this problem with the Honda engine I replaced. Maybe the shaft threads are slightly larger than the 3/8 24 fine specified ??? ... show more

    • Love it!
Size: 173cc
My 20-30 year old third generation hand me down push mower finally died. I looked at buying a new one but you're looking at $500-600 to get a decent quality replacement and even those aren't really great. This costs a fraction of that price and while I was very leery of buying a cheap Chinese no name Amazon engine I've heard really good things about these Honda clones. So far it's been pretty great. Starts up first pull, every time. As a matter of fact the first time I went to start it I almost threw out my shoulder just because I pulled the starter way too hard. I was expecting to have to give it a hard pull like every small engine I've ever started but this engine requires much less effort. I'm still a little leery about getting replacement parts and we'll see how long it holds up but again so far I'm really happy. I would recommend flushing it out with oil before starting and changing the oil a few times after running it briefly as it had a lot of metal flakes in it from machining but that's true of even new name brand commercial engines I've used in the past. Also while it did bolt right up to my existing mower deck I did have to tap the holes in the engine and you may have difficulty finding a pulley to run the self propelled drive belt. I also needed to add a throttle cable. Just be forewarned that while it isn't a difficult install you will have to do some work to make it work but it's worth the effort. ... show more

    • Awesome value for the money.

I had an old worn-out Briggs Sprint on a wheeled trimmer. Being the cheap Dutchman I am, I wanted something affordable to just throw on there and go. I found the best value in the Bilt Hard here! I started out by assessing the shaft diameter. It was exactly 7/8 and keyed perfectly for a vertical Briggs setup. Flipped it over and lined it up, and the holes matched perfectly! I ended up having to tap two of the holes to accept bolts, but I just ended up using some bolts I had on hand. The third hole is a blind tap with a fine thread 10mm bolt, which is included, and works perfectly fine for what I need it for. Keep an eye on starting procedure on this one. I think the ignition timing might be a touch skewed; it will want to buck back when it’s hot, but if you’re expecting it it’s not a big deal. What do you expect for $160? Great value. ... show more

I pulled an old Sears Suburban SS16 could been a 18HP originally, with an Onan twin out of the weeds, been sitting around for 15 or 20 years. I needed to do some dirt work on the drive. Wasn't worth spending a $1000 on to get a twin engine, I wanted an electric start too. Looked at reviews, and didn't want o spend extra $100 to get one from the china tool store locally. So chose the 420cc Bilt Hard, drilled the holes bolted it out and started on the third pull. I still hadn't hooked the electric start up yet. Starts easily. I've got about three hours onit so far, maybe a bit more, on the third tank of gas. Wouldn't know this classic from 1976 didn't have the 18HP engine on it, I've run at only about half throttle and it has more power than traction, and its dozer blade just pushes, hit a solid rock etc and the engine doesn't bog down, it just goes to spinning the tires and diggs. Time will tell how it holds up, so far, no complaints mechanically. The one gripe is there is nothing in the paperwork about wiring up a battery I seen, no specs on what the charging circuit or if it even has one, That is the reason for the four stars on install..... I would recommend the 420cc Bilt Hard to anyone looking to repower a classic garden tractor. It revived an old workhorse... Will it power a mowing deck? I can't say as I never intend to put a deck on this one, its just for gardening and dirt work.... ... show more

    • For less than $150 this engine is impressive
Size: 212cc
I bough this to replace the worn out Techumseh on my snowblower. I was originally looking at grabbing a 212 predator but this popped up on my search and was about $50 cheaper with free shipping. The seller also had a $20 instant coupon so for $129 I got a brand new 7hp engine. I added oil and fresh gas and it started on the first pull. I ran it for 20 minutes at mid throttle to break it in and it ran very smooth and is much quieter than the old techumseh. We’ll see how it handles the winter snow but I can tell already this thing is going to work really well. Highly recommend ... show more

Perfect. I did have a small issue and customer service helped right away and got me what I needed. I would choose this model again over the competitors item any day.

    • Installation was hard
Size: 212cc
This is a very good motor so far. I replaced the one I had on a log splitter. The installation was difficult because you have very limited space nothing was bad about the motor the splitter design was the problem. It works great you have to read the starting process a few times to get it right. Great motor I would buy another if I ever need one. ... show more

Size: 173cc
I used it to re -engine an old craftsman edger, took a bit of doing with tapping out the engine base mount holes and such but well worth the time and effort. This engine started on the third pull the first time and one pull every time after that. Powerful and very quiet.
