what 4 stroke engine?

[atombikes]

Harbor Freight

What about the 79cc Harbor Freight engine? I think it is a little wide, but it seems it could still be frame mounted? It can be had for less than $100 with coupon.

Honda GX35 is the only way to fly if you are considering a four stroke.

I am not sure about that, in my experience Subaru ECO 35 is the way to fly, I own one.

Subaru ECO 35 still made in Japan, reported 30000 miles runs with no problems.
You can get it for around $150 (limited time and quantities)

Honda GX outsourced to Taiwan, price $200 + without clutch.

Some people on this board report dissatisfaction with Honda 35GX power.

That,s the bottom line.

Seem like a lot of loose info floating around here these days.
Let's face it, people are prone to recommend what they own just to validate their purchase.

I own a bunch of Robin engines and am pleased with them but I'd like to see the source for any testimonials about documented 30K miles. These are weedwhacker engines we're talking about.

Also, I like to know where the rumors about Honda GX engines suffering any quality issues or being unpowered for their displacement come from? BTW, the Honda GX series micro engines DO come with clutch shoes and spring.
Sorry, but this just smacks of unfounded internet misinfo.

HF engine is not any wider than Subaru 35 or Honda 35.

I own one, just separated it from the pump (HF $91 with State tax) it will fit frame mount better than Titan or Honda 50GX and tip the scale at 8.5 lb with tank and clutch installed, compared to Titan or Honda GX 50 at about 12 lb.

I have Subaru ECO 35 ($165 shipped) and Mitsu clone HF 52cc 1.9 HP ($91 ) .

Love both of them.



52 cc Mitsu clone I am going to use to propel my fat *** around mountain single tracks LOL!

Subaru 35 ECO the little gem always starting at first pull serves me well riding around the town at 25MPH


Each beats any HT junk, and I do not care if you paid $100 on ebay, or those "High quality" HT kits for $300+

They are all junk (HT engines)

My Subaru 35ECO came with shoes and spring too.

There is no "misinfo" than you can buy Subaru 35 for much less than Honda GH35.

They are both comparable engines.

Rumors about Honda GX being underpowered might be justified.
Just check with some members here. If you want names I will forward the names by private email.

There are no "rumors" about Subaru 35 and Honda 35 origin.

Subaru 35 ECO is still made in Japan, while Honda 35 GX is outsourced to Taiwan.

Thats the bottom line.

yep... junk. $100 on ebay or $400 on rock solid... both are junk.


and the subaru eho35 is a little gem isnt it.... :helmet:

Honda GX25/35 are built in Honda factories in Thailand. Not 'outsourced to Taiwan.'

Also, the HF engine is wider than the Honda/RS engines, especially when you consider the drive shaft protruding.

Here's an the link to an end photo that was posted not long ago

Taiwan or Thailand, my point is Honda engines are not made in Japan anymore.

You are right about the HF engine, I had HF 52cc engine in mind. My mistake.

The Honda plant producing the M4 engine series is a world class state of the art facility, Honda is justifibly proud of it. 5000 associates producing 2.1 million power products and 1.5 million motorcyles annualy.


I wasn't going to say anything negative about the Robin, but you forced me to present the facts.
The Honda has ample power and a superior oil system to any of the other mini four strokes.None of the other engines have an oil system that centrifugaly filters the oil to keep metal particles and heavy solids from entering crankcase.Thats the bottom line.
The Honda doesn't have the inherent weaknesses that the Robin EHO series have, namely a flywheel that is hung off the crank well away from the engine subjecting the crankshaft to unecessary loads and crankshaft whip.
A check ball valve system in the oil metering circuit that can be tempermental (a ball wedged open renders oil system inoperative)
The worst part is the rubber hose oil pickup that breaks off at the fitting or looses the weight to keep the end in the oil and no longer picks up oil.
You can keep a Robin full of oil and still lose the crankshaft assembly or score cylinder due to these problems, I've seen more than one of each on high mileage trimmers. You basicly end up throwing the engine away and replacing it.
As long as there is oil in the Honda it gets oil. Thats the bottom line.
Don't get me wrong I'm not bashing Robin, just stating the facts.

I've owned at least one each of the RedMax, Ryobi mini four strokes on the market, at least 2 EHO35 engines and probably a dozen Hondas.Worked on over 2 dozen Honda M4 engines ranging fron GX22 to GX35 and many EHO25 and 35 engines.
Working on these engines for 10 years in various real world applications and dyno testing, hands down the Honda GX35 is the best performing four stroke under 36cc.
Guess I'm a noob that doesn't know anything...

Both make engines, new in the same displacement class, with gas tank and shipping can be had for within a few dollars difference. This is for normal retail availability not some limited time liquidation price. I bought a NIB Honda GX31 on close-out six months ago for $99 + shipping.

Rumors about Honda GX being underpowered might be justified.

I've addressed these 'rumors' before seeing they speak not as I mentioned "being unpowered for their displacement" but the futility of logic in comparing a 52cc engine to a 35cc engine IE: 50% larger.
