They report 3 hrs/1.7 gallons. Well I run a 12v 1 wire alternator to charge Deep Cycle Batteries. Just a little faster than an idle is how fast I keep it running. I run on average 9 hours on those 1.7 gallons or from dead battery "11.9 to as low as 11.5" volts "dead" battery to fully charged at 12.7 Volts at the end of a 10 hour period, 1 hour cool down after the charge. That is a 2 sets of 6 v Deep Cycle batteries wired as 12 v. Oh the 11.5 V is more than enough to start this 18 HP motor set up. I am pushing 400 hrs on this motor. The location has no electric power supply, batteries and inverters... Refrigerator and hot plate and other tools...
Bought this for my sawmill band saw.
The good.... it's a lot of HP for the money. Much better than the stock 8hp motor I replaced.
The bad.... Very poor packaging, the cheap box and foam fell apart during shipping, casuing the pull starter cover to become very dented. Also, there was no wiring instructions. The starter key box assembly was not installed so I had to spend 2 hours trying to figure out how to wire the starter / battery. I searched the internet with no luck trying to find a wiring diagram. I found MANY other complaints about the same problem.
UNRESOLVED: The engine wont cut off with the key. Its starts normal with the key, or with starter cord, but the engine cannot be cut off with the key. I have to use the choke to kill the engine. I emailed Maxtool about this last week, but got no response. So I am writing this review as I sit on hold calling their support line.
I bought this engine for my homemade band sawmill... I needed something with the power to push through hardwood and softwood, but didn't want a big bulky engine that limited my mills mobility. This engine is well shaped, similar to the picture, but not the same... As for performance, it does it's job, but the controls, starter, solenoid, and key start box are very cheaply made... The screw for the solenoid stripped with just a wrench and little pressure... The wiring diagram that comes in the owners manual doesn't match the actual wires on the engine or on the key box (I removed this altogether)... The throttle control on mine is made from thin galv metal and if used too much feels like it would bend or break clean off... As for the shaft and engine performance, it's great - usually starts on the first or second pull... It seems to have plenty of power for my sawmill, but I have nothing to compare it too...
Solenoid is garbage
No good wiring instructions
Controls are very cheaply made
Cost is excellent
Shaft is well machined
Somewhat quiet running
It seems solid - no valve clanking, etc.
Works well overall
I gave it a 4 star rating for the fact that it's a good engine and does it's job regardless of controls, key box wiring, and solenoid issues... 5 stars for the engine itself and 1 star for the controls, wiring, and solenoid... Overall, I think 4 stars is fair for what I paid... I would also buy this engine again if I needed another one...
