Question and Answers

Q:

craftsman chainsaw 358.34118 gives 2.1hp but its a 4hp. why does it only give 2.1hp & not 4hp?

A:

Thank you for your question on the H.P. rating on electric motors in this type of application.

The way it was explained to me years ago in the electric motor woodworking application, is that the motor is rated at top speed no load and the instant that the saw blade or saw chain touches the wood is were they take the rating from.

That's why the manual say's 13 amps and 4 developed or peak horse power rating. The working watts or horse power is considerably less than that. This is an illusive measurement at best because of all the variables.

This is misleading and if you walk into a home center and look at all the tools, it is still a practice today of inflating the useable Horse power rating. There any number of web sites that talk in detail on how they figure this rating, but as I explained above this is it in a nut shell. (Marketing)

When I go shopping for a new power tool I just cut the horse power rating in half to get the true usable horse power. And the cheaper the tool the poorer the quality of the motor the less usable power you will get.

Q:

What year is my 4hp tiller made model 143-147032

A:

We can't be sure if your rototiller was made on the 85th day of 1977 or 1967. The number 785-50262 is the date code. The exact year was not specified.

The 7 in 785 indicates the year of the decade, the 85 indicates the day of the year. By looking at the parts diagram we are sure the year was before 1987. We can't be sure if it is 67 or 77.

Q:

Craftsman Edger Briggs and Stratton 4HP motor

A:

Thank you for your question and I understand your concern.

Based on your symptom and details, the problem is in the carburetor. The carburetor will likely need to be disassembled, cleaned and possibly adjusted. If you do not feel confident in dis-assembling and cleaning the carburetor, I recommend taking the edger in for repair. There is nozzle that runs down from the base of the carburetor and down to carburetor bowl that could be restricted. 

Pushing on the governor rod should not make any difference in starting. The governor is used to increase the RPM when the engine is under a load. If you watch the governor rod as you move the throttle back and forth it will move the governor rod which opens or closes the throttle shutter inside the carburetor. There is a governor rod and a lever. There should be slight tension on the governor lever when moving it back and forth. The governor is controlled by RPM's and the governor spool and gear. The governor spool and gear is located behind the cylinder cover. It's not likely a governor issue but more so of carburetor issue. I added a link to the  Operator's Manual where you veiw the parts of the carburetor and the governor spool and gear. I do not recommend attempting to access or service the governor. If not adjusted properly, it can cause the engine to over rev and possible cause personal injury and blow up the engine.

If you get to the point where you need to have a service technician fix this problem, you can carry the edger into your nearest Sears Repair Center or Sears Store. Here is a link for the Sears Service website that has information on the nearest repair facilities in your area:Sears Home Services.
