Hello,

I have a JD14SB (Actually a JD14SE… electric start) I bought off of Craig’s List. I’ve cleaned the carb., pulled the spark plug, and drained the oil. I’ve downloaded a parts list but now I find myself in need of an owner’s manual. I’m interested in the spark plug gap, initial carb. adjustments, and all other literature concerning maintained and proper operation.

Does anyone have a manual they could email me?

Any and all help is appreciated.

21”
14SE
Kawasaki 4.5HP

Carb:Mikuni Corp.


Thanks,
Bob

Thanks for the reply Mowersnob. I’d found this previously but I can’t find an area that addresses the concerns I have.

“I’m interested in the spark plug gap, initial carb. adjustments, and all other literature concerning maintained and proper operation.”

In addition…

I've got it all put back together and it's surging. I know next to nothing about these machines. I've noticed that the throttle plate is cycling open and closed (a little) in sync with the surging. It surges at all speeds. I noticed this linkage is connected to the governor. I don't know if this is a result of the surging or the reason for the surging.

It seems to surge a little less under the load of the blades being engaged.

I meticulously cleaned the carburetor and can’t believe there are any blockages yet the needle screw circled in red below has no effect.


I ran across this info and saved it for future reference hoping I would be able to figure out what the author was talking about but it’s still beyond me (red text).

“…as it is a 14sb, it has a kawasaki engine on it. when you push the throttle lever all the way forward, check to make sure the choke linkage is closing all the way on the carb. if not, pull the lever back to the fast position and see if 2 holes line up on the plate the cable hooks to. this is the throttle plate. if the holes don't line up, loosen the cable retaining screw and move the cable to align the holes.”

I've also read "Surging 318 update" http://www.mytractorforum.com/showthread.php?t=142016&highlight=surging+kawasaki+deere posting plus all other applicable info I could find but am still at a loss.

Gas, fuel lines, oil (NAPA 30 wt. high detergent), oil filter, air filter and prefilter are all new.

Gas tank, gas valve, and gas filter (at bottom of tank) have been cleaned, but I’ve yet to install an additional, new inline gas filter.

Spark plug cleaned and reinserted without changing gap.

Back in 2008 mine started surging when under no load, would run fine under load when cutting grass and would not idle at all.

At that time I was busy with work and did not have time to monkey with the carb so I just replaced it with a new one. It fixed the problem so I'm guessing your issues are still carb based.

These mikuni carbs are pretty tricky to the point that my local JD service center prices their service of carb rebuilding to within a few bucks of the cost of a new one....... meaning even they really don't want to deal with them.

Thanks for the info snob.

I'll pull it again and run some guitar or banjo strings through the possible problem places and see if it helps.

Bob if you want to send it to me-my 14sb wouldn't even run. A few rounds of my ultrasonic cleaner on the main jets and pilot jets did wonders. I also used banjo strings and carb cleaner. I did notice the Pilot jet was uber sticky-might want to make sure that is REALLY clean.

After running the jets through my ultrasonic cleaner it fired up in one pull and has been runnign great since.

Thanks for the offer GTP; and thanks for the idea but I've got a 3 Qt. Crest here that need a little work to get it going (pulse not getting to the transducer).

If fixing it's going to take a while, I have a friend who is a metal machining equipment dealer. I'm sure he has other working ultrasonics. If not I might just take you up on your generous offer.

They are wonderful tools to have around and I almost forgot I had one stashed away.

Thanks again,
Bob
