Question: Spark Plug

cory

I changed the spark plug on my idc 400 tiller. The problem is the spark plug only fires on the 3,4,5 pull. So I'm thinking its the coil pack. I cant find one to replace it with. Or is there any other thing I can do to keep it firing?
Thank you

Question: Carberator Adjustment

Duke

I received an IDC 400-1 cultivator that someone tried to repair by removing the primer bulb and whatever else, I don't know. I replaced the bulb and fuel lines and the gas cap. I was able to get it running for a short time, but now it won't even try to start. Is there a starting point to setting the carburetor to get it running and, if that happens, what is the procedure to adjust it from that point? Any help will be appreciated.
Thanks
John

As a first try - I always start by setting both the idle and hi-speed fuel/air mixture adjustment screws 1 1/2 turns counterclockwise from their seated position. If that doesn't work, go to 2 turns. Once running, fine tune the adjustments. It sounds as though someone may have removed the locking caps on the two screws, so after you get the machine operating, you will need to either replace the locking caps or keep adjusting these adjustment screws if performance deteriorates. Have fun!

I found the answer. The needle valves are marked with either L(low) or H(high) and the basic adjustment is 1.5 for the low and 2.5 for the high. This is from full clockwise in and back out to the setting. If you get it running from that point, then you can fine tune from that Point.

Question: Wont Stay On

I was replacing the hoses.I replaced them the same way they came off, though when I follow the instructions to turn it on it will not stay on for more than a few seconds. Please Help.

Hi Brian,

It sounds like carburetor issues to me. I would suspect that the carb is clogged with dirt or old fuel. It could even be clogged with remnants of the old fuel lines. There is a carburetor rebuild kit available. There where two carbs used by Ryobi on this model. One was made by Zama. The rebuilt kit for it is part #791-180090. The other was made by Tillotson. The rebuild kit for it is part #791-147170. Both of these parts are available from http://www.ereplacementparts.com .

I hope this helps with your repair!

I am repairing a IDC 400-1 31cc Model 400 cultivator (SN 002 020 205. The fuel lines are disconnected. As I see it, I have 6 fittings, therefore requiring 3 lines. Two fittings in the gas tank (left and right), two in the primer bulb (front and back), and two in the carburetor (front and back) as viewed from the operator side. Could you please help me figure out what lines go where?

We have put together a diagram that will hopefully help you to replace the fuel lines on your tiller. You can view the diagram at the following link...

Good luck with your repair!

Starting at fuel tank: Outside line (the hose with fuel filter attached) goes to the upper fitting on carb (black plastic). Lower side of carb (smaller brass fitting) goes to suction side of primer bulb (shorter barb usually marked "in"). Return side of primer bulb (longer barb) to inner fitting on fuel tank. If primer is different just put finger on/at barbs and feel for air pushing out or suction on finger. Buy at least 2 feet of hose (there are 2 sizes, but 1/8" fuel hose will usually work for both). Push more than amount need through bottom of tank and pull through filler opening. Put some type of lubricant (liquid soap/spit, etc.) on hose and pull filter/return fitting through bottom of tank. Route to proper location and cut to length. It would be a good idea to put a new filter in at this time. Also cut old pieces of hose off fittings with a razor blade and use needle nose pliers to push hose on (especially on barbed plastic fittings) so they don't break.

Mark, you seem like the guy to ask. I'm exercising my fledgling small engine repair muscles by trying to repair my grandfather's IDC 400. I've ordered and received a new plug, primer assembly and fuel assembly. All of the fuel lines are rotten, so I need to replace all, but the fuel assembly kit only came with 1 of the 3 lines I need. Really, I think I just need a length of the hose itself, that I can then cut to fit. Is there a retail way to purchase this particular gauge of fuel line? I don't know which other parts to order to get the hose I need, and I really don't want to wait 3 more weeks for shipping, only to [probably] find I still don't have what I need. Thanks for any insight you may offer - Will

Hi Will,

The manufacture sells the third piece of line (the return line) as part of teh fuel tank assembly, part #753-04306. That is kind of an expensive way to get a piece of fuel line though.

You could take one of the other lines that you already received to your local mower shop. There is a chance that they could match it. That is kind of a long shot though. Most of the fuel lines used on the Ryobi engines are metric and smaller diameters than what they usually use at the mower shop.

I searched around in our warehouse a bit and found a short length of fuel line from another manufacture that appears to be a size match. It is part #530069571.

I hope this helps!

I thought I would update this thread with some new info regarding fuel line routing. We have put together an article and video that provides the fundamentals you need to know to figure out the line routing on any 2-Cycle engine. You can find the info at the following link...
