Let's get back to basics. Have you done a vacuum/pressure test on the engine to determine if you really have a leak? What about fuel starvation? Have you checked the fuel filter and line for kinks, leaks, sucking flat, partially plugged filter, filter not sitting on the bottom of the tank, etc...

Dug a little deeper. The engine is item #44 in the parts diagram, which is described as a Briggs 133412-0059-01. The carburetor part number is 495652, a Nikki carb. Lots of Chinese copy carbs on Amazon and Ebay. Search for the part number. Hope this helps.

Apparently this is a Sears/Craftsman branded engine. Made under contract for Sears by someone else. We need the model/type/code numbers off the shroud to figure out what you have.

Pinkway saws have been getting good reviews. Apparently they are of above- average quality. There have been reports of people ordering a Pinkway and getting a Chainsaw brand instead. It is most certainly not a 63cc engine. Not a 62cc engine either ( often marketed as one) Not a 58cc engine (...

I love the ad copy for these saws. It shows a powerful 3.5hp V-twin 4-stroke engine that idles at 9000 rpm. Maybe I should get one to play with.......

My saw has the single open transfers. I ordered a replacement cylinder with dual closed transfers to play around with to see if it makes a difference. The muffler is a 3-port, but is a totally open can. No baffles, you can look in the ports and see the piston. One more thing to play with.

I recently got a 5200 Zenoah copy off Aliexpress for $64.32 shipped to my door. That's the cheapest I have seen them recently. The price changes constantly, so keep your eyes open if you are looking for a bargain. It arrived in 4 days, shipped from a US warehouse. Cheap plastics, but nothing has...

The loctite on the threads can indeed make the clutch hub hard to remove. The clutch tool and a long breaker bar is the best way to do it. Steady torque rather than beating on it with a hammer or an impact driver. I do not use the metal piston stop, I use the rope in the sparkplug port method...

Chinese-made saws are cheaply made copies of someone else's older model saws, usually Stihl, Husqvarna or Zenoah. You need 3 things if you are going to get involved with them: Tools Skills Inclination to work on your saw. If you have the basic Tools and Skills to work on saws, you can improve...

Definitely hit or miss. You have to balance the cost vs. time wasted if it doesn't work. I think my success rate is currently something like 60%. Doesn't seem to matter whether it is a cheap no-name item off Amazon/ebay or if it is a "brand name" like Hipa or Proline. Check the return policy...

A while back, a member on this site, or possibly the other site got a 4-stroke saw called a Senix. The first one had problems, so the vendor sent him a second one to warranty it. The member ended up giving both away for free because they were such a horrible POS. Hopefully this one is better?

The add I pulled up is selling it a lot cheaper, but it doesn't come with batteries. It's also advertised as 29.8KW (almost 40 HP!) A much better deal! How many AAA batteries do you suppose it needs to get it to run?

Ditto on what Redline4 and Shane1 have written. It may not be how an engineer would do it, but that's how it gets done All day every day in every shop in the USA.

Take a fuel sample. Water or Diesel in the tank? Did it over-rev and bend a pushrod/ pop off a rocker? When taking a compression reading, remember the compression release is going to cause a low reading. A reading of 50 PSI is still ok. The old thumb over the sparkplug port test is just about...

20 oz. should be correct for this engine. Double check with the dipstick, if it has one, or the method mentioned above by Hacskaroly if it does not. 30W is recommended unless you are using it in cold weather (probably not). You can use 10W30, it will start easier but it may consume some oil in...
