Question about Ryobi 30 Cubic Centimeter Curved Shaft Gas Trimmer

3 Answers

Ryobi 700r 31cc 15" Trimmer

I got this from my neighbor who couldnt keep it started.
After alot of pulling I had the same problem.

- I replaced all the gas lines, but the one of two lines going to the primer bulb appears to still leak. I pulled the bulb assembly off and slid a similiar line of both connections, the longer fuel inlet tab appeard to be tighter (this is the line that draws fuel) the shorter tab which pushes fuel is the one that i believe leaks.

- When it starts it will run choked, dies when choke is turned second position.
- I have cleaned the carb, diaphram appears in good shape.
- Another thing, there is a line with a filter coming from the tank, and a second line that just pushes through the wall of the tank? Am I missing a part or is this how it should be.
-What are the correct connection of fuel lines, dont know if i got them wrong, also there is a white plastic splice piece in the line from the tank to the carb? is this correct, seems like a longer line would be more effective?
- How do you get the plastic cap pieces off the (L) and (H) adjustments screws so I can clean these jets out.
I want to get parts but the numbers dont appear to match anything on line>Here are the numbers, can you help out?

Just break off plastic caps to access the low and high speed jets. They are there because of government regulations to prevent users from adjusting carb in the field. They serve no other purpose.

Supply line with filter is suppose to be one piece from the tank to the carb. If it has a barb coupling in the middle then someone must have tried to patch the line at some point. You can get a replacement line and filter as part #682039 by searching online or ebay. Or you can just order line and reuse filter if it is not plugged. Required line is 3/32 ID x 3/16" OD. Both dimensions are critical. To replace line you have to take retaining ring off the bottom of the fitting on the tank (use a knife or scraper to pry it off the bulge in the hose) and push the filter fitting into the tank. Remove from tank through the fill opening. Remove piece of hose that is still on the barb. Push on new section of hose all the way to the top of the barb and right up to the filter. Put other end of hose through tank fill opening and through hole in bottom of tank. Use a piece of wire or a straightened paper clip to guide it to the hole. Pull hose through until the bulge gets to the opening. Pull hose firmly, but carefully so the hose stretches enough to allow the bulge to go into the hole in the bottom of the tank. Stop when the bottom edge of the filter is about 1/8" from the inside bottom of the tank. You should see enough of the barb end sticking through the tank for the retaining ring to be replaced on the outside bottom of the tank. If not enough exposed, pull hose through a little more. Thread line to carb input and insert. Inlet fitting will have barbs or a bulge on it. The return fitting on the carb is a straight tube with no barbs. The line from that fitting (3/32 x 3/16 also, as all lines are) goes to the top (suction side) of the primer. The other side of the primer has a line that returns to the other opening in the tank.

The return to the tank must have a fitting similar to the filter fitting, but without the filter. It is a barbed fitting with a flange ring on the end that is inside the tank and it has the retaining ring on the outside just line the supply side line. It sounds like you are missing that fitting, because you are describing the hose just being pushed up into the tank. Without that barbed fitting in place the tank will leak gas. The bulge in the line caused by the line fitting over the barbs is what seals the opening. You can order a return line kit 147290 from MTD parts that will have the line, the barb fitting and the retainer ring. In a pinch you could get use an 1/8" hose barb from a hardware store and just arefully pull it through the opening so that the bulge in the barb/hose combination is sealing the tank both inside and out. You can get by without the retaining ring. Otherwise look for a junk IDC/Ryan/Ryobi trimmer to scavange parts off of.

Sounds like you may still have a carb problem to deal with. Did you remove the needle valve to make sure it is not stuck or inlet plugged or restricted? Fuel screen clean? May need a diaphragm and gasket set. Good luck.

I had the same problem with my 700r and found that if you remove the internal strainer screan or
( Spark arrestor screan ) that is located inside the carb. the engine will get the proper amount of fuel
and will run out of the choke position. the cause of this problem is usualy due to storeing the trimmer
for long periods of time with fuel still in it witch clogs the screan.

hope this fixes your problem.

Taz .


P.S. you will have to remove the carb and take off both side covers and use a needle to pop out the
screan.

I'm not an expert on trimmers, but I do know that it sounds like the fuel filter located inside the gas tank at the end of a hose is plugged and needs to be replaced. You can pick one up at the local hardware store. Hope this is of help to you.

93 deville burns alot of fuel, like a gallon a mile; no leaks in fuel line. Any suggestions?


A ruptured diaphragm in the fuel pressure regulator will let extra gas enter the engine through the vacuum line to the regulator. Pull off the regulator vacuum line. Any evidence of gas? Let the engine idle a couple of minutes with the vacuum line off. If any gas starts coming out of the vacuum line nipple on the regulator, then that was the problem. Replace the fuel pressure regulator.

If it has set for 2 years, you did the right thing by draining the old gas, and you would be smart to
change fuel filters as well. if you can pull your spark plugs and clean real good , better yet just
replace them, so you will not have to wonder . have While you have everything apart look at your
plug wires, bend them and look to see if you see small cracks in the boot or wires, is so replace
being that it is an 1985 your coil could be weak , but take your spark plug put back in the wire
and rest the other end of the plug up against the head and turn your motor over a few times looking
at the end of the plug you should be seeing a good blue spark, if not replace it. look at carbs to
see if everything looks free of rust and any vacum lines have cracks, if so replace. put 1 bottle
of heet in your gas tank and then use your new gas, spray carbs with WD-40 put everything back
together and crank it up. You will be very proud of your self. Good luck

The filter sounds like the weighted type. If so, it keeps the pickup line on the bottom. The piece that keeps the tube in the tank can just be a piece of a little larger tube pressed over the pickup tube. Yoi will have to thread new tubing in and pull it out the fill hole. Place the keeper on the tube and press the filter into the pickup tube. Once you are ready, pull the pickup tube inti the tank until the keeper touches the tank side. Hook up to the primer and try it. Good luck...Lee

My truck wont run. Why?


If it is flooding it might be a fuel pressure regulator, when it floods hold the pedal to the floor until it revs up, this should clear out the gas and get it started but the problem will remain until the fuel pressure regulator is checked or replace it is located at the beginning of the fuel rail on top of the motor it has a vacuum line going to it. Replace the vacuum hose first also if it appears to be wet with gas replace it. If it checks out ok or problem persists pull out a spark plug and have an assistant turn over the motor as you observe the spark it should be a bright purple or blue color if not it is a weak ignition issue repalce the plug wires and plugs along with the distributor cap and rotor. If problem still persists replace the O2 sensor and ignition module.

How do you start a new toro 6.5 hp lawn mower. I borrowed it from my neighbor,but it has 2 levers to pull back. I'm clueless!


One lever is to make it go - wheels will turn & pull the mower..
The other lever is to keep it running - it this lever is released it will shut off..
This is the lever you need to keep pushed for it to start..

When starting - there should be a rubber push button on the engine near the carb.. Push it 4 times before starting.. This pumps gas into the carb for quick starts.. Good luck ;o)

We put in a rebuit straight six and have spark gas but ddoes not start tried to time to tdc and dist is at number 1 but still nothing help


It sounds as if you have it lined up,spun the crank to tdc and verified the intake valve on 1 opened prior to hitting TDC,did you crank the motor alot?Possibly try pulling all the spark plugs and allow any fuel in the cylinders and on the plugs to evaporate.Gasoline conducts electricity and if there is liquid fuel on the plugs they wont allow them to arc fully if at all.If you want to speed it up pull the distributor(mark its placement)this will keep the injectors from firing,and crank the motor.The compression will force alot of the raw fuel out.I have personally used this technique with great results.Rate this only if it helps.
