Kawasaki 12.5 hp won't start after changing crankcase cvr gasket
Comments (10)I was out of town a couple of days and haven't been able to respond. Thanks for your response. I tried to be very careful not to turn or move anything. I did not check the timing marks when I put the cover back on, I only focused on getting the plastic governor gear meshed properly. I don't even know where the timing marks are. Considering that it won't even try to start, gets a good spark, and after pulling the cord numerous times gas will be visible in the carb cover around the choke plate, along with an occasional backfire, it does sound like the timing is off. Do you have any advice on setting the timing or maybe a website that might help? Obviously, I'm not an expert mechanic and hate to remove the engine again, but it looks like that's where I'm headed. Thanks again....See MoreJD LT180 and 17hp Kawasaki
Comments (21)I think that highly unlikely (in regard to the gasket causing a surging issue). Where I was leaning (and maybe Bill too) regarding piece of anything inside the tank is that these things can get sucked against the pick up tube and act like a "flapper valve". The only problem in this case is that your surging seems to come on after only a short run time. A flapper situation is almost a "random act" in that it must drift past the pick up tube at just time right time for it to get sucked into place............that simply will not happen like clockwork. Knowing that this is a new fuel pump, I have to ask: Did you replace the pulse vacuum hose that operates the pump? If that hose has a crack or fissure preventing the pump from getting a full stroke with each alternating pulse from the crankcase, the darn float bowl may be running out of fuel when fuel demand is high (wide open throttle)....See MoreJohn Deere LX176
Comments (12)SUCCESS!!! Here's what I did to fix the pump on my LX176. First, I diagnosed that I was getting good crankcase vacuum pulses. I hooked up my vacuum gauge to the hose on the crankcase, and cranked the engine. Indeed, I was seeing pulses that were peaking at 6in/hg. These should be enough to pulse the pump. Next, I removed the pump and started playing around with it. I sucked on the vacuum nipple, and could feel the diaphragm inside move, and air was rushing out the little vent screen on the pump. So far so good. I also could feel air rush out the outlet nipple. Nothing on the inlet nipple. Also, I could blow through either direction. Hmm. Doesn't sound like a pump ought to work this way. So I started spraying from the inlet and outlet carburetor spray. Perhaps we were gummed a little inside. I also start cycling the vacuum again with my mouth, sucking a little harder each time. And then, I feel something inside give a little- and the diaphragm was either moving more now, or I broke something. I could feel little puffs out the outlet, but now I could feel little tugs on the inlet. Hmm. That seems good. I give a few more sprays of carb cleaner for good measure and cycle a bunch more. Next, I attach the inlet hose to the fuel filter on the mower, and start the suck cycling. I could see the fuel level rising in the filter, and after a little bit more, a few splashes of fuel started coming out the outlet. Sweet! So, I hook everything up, start the engine, and after a few seconds of cranking more than usual (presumably I was filling the carb bowl), SUCCESS! The SOB fired right up. I left her idling for a few minutes to make sure, and she kept purring along. A lot of the stuff I'd been reading on this type of pump came from the vintage Japanese motorcycle scene. Should come as no surprise that this Kawasaki engine works the same way. I think one thing I'll do is keep an eye out on ebay for a spare pump to have....See MoreKawasaki 14 HP Engine Problems
Comments (45)Now we may be getting somewhere. Coil # 21121-2069 is for "AS&BS" engines, while coil# 21121-2086 is for DS&ES engines. The older "AS&BS" engines use the external ignitor module while the "newer" DS&ES engines use a coil with internal "triggering" circuity, a self-contained unit. I'll order the 2086 coil & hope this ends my "Frustration". In the expectation of this outcome I will thank you now for all your help & effort in this dilemma. On the outside chance that I'm being too prematurely optimistic---I,ll be back!...See More- 14 years ago
