gwgdog66 23 #26 Posted June 4, 2011 OK...dumb question time. I have a small plastic tank that came from a push mower. Can I have someone hold that tank up above the carburetor and allow fuel to flow via gravity? Then have the fuel pump supply hose stuck in the gas can? This way I can verify it is not the fuel pump and see how much the pump is actually pumping. Don't think I have to use the pump if the gas is high enough for constant flow. Thanks in advance. Yes. It will gravity feed. Share this post Link to post Share on other sites
hcminis 1,700 #27 Posted June 7, 2011 Well...still here and same problem only now have more. Starting to be a money pit... Set up a gravity feed tank to try and bypass the pump and the switch did nothing. The other day I removed the molded plug from charging system under the dash and it was a little melted. So, had to do a little old fashion hot wiring to get the dern thing to turn over. Finally got it started and same problem. Neighbor said sounds like it is getting too much gas and not burning off. So, tired of wasting time and gonna order a rebuild kit for the carburetor. Anyone have a good complete kit? Hate buying from the bay site because you never know what is good and correct. Plus, trying to stay reasonable. Additionally, the dern hydro engagement lever spring broke and now there is a leak on the cylinder lines. This thing is really trying my patience that I am desperately trying to do better at controlling..... Thanks and will keep updated. Share this post Link to post Share on other sites

hcminis 1,700 #29 Posted June 17, 2011 Still trying to get a rebuild kit for the carburetor. Called NAPA and they were so rude that I may NEVER step foot in a NAPA store again. Found one on fleebay but still can't confirm what carb I have. There are only a couple numbers and NO other distinction anywhere. Just about to throw in the towel and sell this one. Need the space and found a 701 that can be bought cheap. Share this post Link to post Share on other sites
rmaynard 16,333 #30 Posted June 17, 2011 Post a picture of the carburetor here. Someone will be able to identify it for you. There are only two, one has a fixed jet, the other is adjustable. I think the same kit works with both since the carburetor kit only contains a float valve and seat, and some gaskets. Share this post Link to post Share on other sites
boatman 3 #31 Posted June 22, 2011 :hide: I would say it still sounds like a carb problem and not getting enough fuel. It is common for an engine to back fire some when trying to accelerate or when putting a load on it if it is starving for gas. I would try to run a small piece of wire thru all holes in carb and in the high speed needle valve. Sometimes blowing air thru it is not enough to dislodge a small but of debri. Good luck.

bigd 0 #32 Posted June 22, 2011 is your throttle shaft bushing wore out? Share this post Link to post Share on other sites
shorts 182 #33 Posted June 23, 2011 pull the plugs and check the compression, if its good check for spark at the plugs, install new plugs. if you have compression and you have spark, it's got to be fuel. fill up a small pump oilcan with fresh gas, open the choke and throttle wide open and squirt some gas in the carb while you crank the engine, if it fires and runs go to your local kohler repair shop and order a carb kit and float and rebuild the carb Share this post Link to post Share on other sites
hcminis 1,700 #34 Posted July 15, 2011 Well, I'm done. Tired of messing with it. Tried everything I can think/know of and still nothing. Carburetor rebuilt twice, fuel pump checked at least three times, new spark plug, different coil, new condenser, new fuel line and filter. Now the key won't work which I'm sure is the rectifier. The dern spring for the hydro engagement lever broke while I was working on it the other day. So, it's for sale. Thanks for all the advice... Share this post Link to post Share on other sites
rmaynard 16,333 #35 Posted July 15, 2011 Now the key won't work which I'm sure is the rectifier. As I stated previously, the engine does not need a rectifier to run. All you need is 12 volts to the coil. The only thing the rectifier does is convert AC to DC and charge the battery. You can connect a wire directly from the battery to the coil and the engine will run. I will go back to the beginning and restate my thoughts. The engine was running fine until you said you ran out of gas. You filled it up, and that is when the problems began. I am not a believer in coincidences, so I don't think you ran out of gas and had a mechanical or electrical problem happen at the same time. I still think it is gas related, specifically the carburetor. But here is one last thought. If the engine started to act up at high speed, and you just assumed it was out of gas, and you filled up only to have a high speed problem, you may have a broken valve spring. A broken valve spring can allow the engine to run and idle, but not run at any higher speeds. Share this post Link to post Share on other sites
hcminis 1,700 #36 Posted July 15, 2011 Bob Yes sir. I did remove the rectifier from the circuit and ran a wire from battery to coil. Will turn over with the key but now won't fire. May mess with it some this weekend and see if there is a broke spring. Just seems the more I mess with it the worse it gets....think that is a Harrison curse though...

At least you're not giving up yet. I wish that I were closer to you. This is the type of challenge that I enjoy. Share this post Link to post Share on other sites
bigd 0 #38 Posted July 15, 2011 the rectifier should nt make it not turn over with the key i wonder if maybe your problem is in the key switch Share this post Link to post Share on other sites
kyhorse 1 #39 Posted July 22, 2011 I just want to add that I went through an almost identical experience with my D-160. Wouldn't run past idle, backfired, carbon, etc. and the more I worked on it the more problems it developed. (Well, I was creating them as I went along.) I did almost all the same things as you, execpt not as well. One problem would mask another, for example I had a fried test lead on my multi-meter and didn't know it. I believe the main starting issue was throttle was stuck wide open, and at some point I had reconnected the condenser to the + side. Eventually I changed out condenser, coil, plug, plug wire, starter switch, and lotsa wires. Once I got it running at all, the thing that really smoothed it out and upped the power tremendously was a genuine old-fashined steel core spark plug wire that was recommended by a forum member who has been helping me with this. This is a replacement wire for the Kohler (from NAPA), and not a modern car wire, which apparently is not really a "wire"! I think you can whip this! Mine runs like a top now(forgetting for the moment that the hydro shaft is stripped and it won't move. But the engine works great.) Share this post Link to post Share on other sites
