Hello Doc, It has spec # 64694

I have heard bad reviews on Walker's valve cover mounted fuel pump. Does anyone have a recommendation of a model that would replace Walker's valve cover style fuel pump?

It's a single barrel keihin. Yes, the clip is installed correctly.

I rebuilt my carburetor, found out gas was getting in my oil then found out my float setting was 26 mm instead of what the manual calls for which is 22 mm. When the float is at 26 mm which would make more separation between the needle and the float, is it possible the the float could get stuck...

I was putting the carb back together with the o ring kit I received and the the tiny o rings are actually round which won't fit in the holes. I believe I need the flat style to fit in the holes. Any recomendations on the best place to find a kit? I order the first kit from Amazon that matched...

How about fresh motor oil or vaseline?

What is the best method to confirm it is sealing?

Perfect- I confirmed that the carb needed rebuilt and was wondering if the 22 year o-rings, body gasket and needle valve can contribute to gas getting into the crankcase oil.

when you are putting new o-rings on, do you use any lubrication?

Ten four. I just used my mouth. Fingers crossed, replacing all the o-rings, needle valve and the ultrasonic cleaning will do the trick.

I did the blow test with the old needle valve and it sealed completely from what I could tell. The brass seat appears in good condition, I am going to replace the needle valve though. I appreciate the feedback.

I have an arrow pointing to the brass piece the inlet needle valve inserts in. I've had people tell me there should be an o-ring in this brass piece but the engine manuel does not show one. It appears to me the brass piece is the perfect size for the needle valve to seat perfectly without an...

Any recommendation on where to buy the kit of o-rings, gaskets etc. to re-build the carb?

Good point. In the past, I mowed some buffalo that would be dry early season for sure but it was irrigated too. About 75 hours per year in the past. Only mowing one small yard with it now and it's irrigate fescue, dust will be minimal. The air pre-cleaner beside my armrest does not have any air...

I've been told removing the air intake hose and spraying carb cleaner in while the engine is running will help clean up the carb. How long should I spray? Should I spray the maximum that will come out of the can? Should the engine be left at an idle? One other thing is the engine struggles to...

To me it sounds like the RPM's are decreasing. I do have a belt or two that could be replaced and have some small holes in them, but I'm not hearing any squeaking like the belts are slipping.

Thanks for the advice. I believe the metal shroud had to be removed when my guy replaced the coil packs and the the cooling fins would have been cleaned up then.

Excellent. I have an oil change on my list and it's got 150 hours on it, should have done it at 100 hours. Great information that I will put in action. Appreciate it sir!

I don’t know how to tell which cylinder isn’t performing well. 1,100 hours. I believe it’s the RPM that’s decreased.

I've been fighting an issue for awhile where my 20HP Kohler doesn't want to maintain full throttle while mowing, it's close but not quite there. Also, the engine will surge and hunt intermittently. I have done the following to the mower trying to fix it but it's not quite there. I'm wondering if...
