toro not starting

[itguy08]

Sounds like a fuel delivery problem. Are you getting real good flow at the carb end? As in can you drain the tank with the hose at the carb side of the fuel hose? That was the main issue with mine - I have to run it with the gas cap really loose or it will starve for fuel.

Other than that, you can try the carb. That got me from running on 3/4 choke to 1/2 choke. With the new carb it runs like the day I brought it home.

Other than that I'd try the carb along with new fuel line. I've heard of pieces flaking off and clogging carbs before so it's cheap insurance.

It sure sounds like you have the carb clean. On a two year old machine I can't see it being gummed up that bad from one year to the next.
You must be next to a saint.
I would have smashed the S.O.B by now.



I was thinking that I will take the carb off and post some pics of it tonight . this way everybody can see try and see if I need to remove a jet that needs to be unscrewed from the top or side of the carb. looking at pics of other Toro carbs most of them seem to have a brass screw that has a couple of small holes in them that need to be cleaned out so maybe I did not clean this out because I did not remove any screws. ? I have not messed with any screws yet,because I did not want to mess up any of the settings. want to be sure that all of the jets have been cleaned out before draining the gas tank and replacing the fuel lines. when I changed the fuel filter the gas came out of the tank fine and flowed well after the fuel filter. when I sprayed the carb cleaner in the inlet side for the carb it went right to the bowl with ease it seemed. I am pretty confident that the gas cap is not the issue as I have tried it with the cap off and just slight open and it did nto seem to make a difference. if i knew for sure a new carb would work I would buy one but if it did not solve the problem then I just threw more money away. have to admit it has been a struggle to get this thing fixed but it will be satisfying when it is done ... guess I am living up to my brithers saying of patience like a rock ha ha ha ha ha

Can you keep it running with carb cleaner or starting fluid sprayed in the air cleaner opening? If you can keep it pounding away with the stuff sprayed into it, I'd say chances are very good it's your carburetor. As small as some of these passages are it could be just a speck jamming things up.

I was not able to get it started then spray the starting fluid in the opening as it stalls out so quick. I am going to call the Toro dealer today and see what time they are open until. want to talk to the repair guy and see if he can suggest a jet that can be removed possibly I may have missed. can also price a new carb while I am there and grab some new fuel line. since I am off tomorrow I will take the carb off tonight and work on it in my basement in the heat this time. thinking tomorrow I will empty the gas tank and remove it. spray some carb cleaner out of the tank exit hole and fitting where the fuel hose attaches. change the fuel line making sure there is no possible coke point there. if all goes well with the tank and fuel lines any fuel issues will have to be the carb as the fuel filter is new.

What I've done is sprayed a bunch of it in the air cleaner and that is usually enough to get it running enough I can get back with short bursts of other cleaner to try to keep it running.

as promised here are some pics of the carb. I did removed the brass screw at the bottom and there are no holes in it on the threaded part. had to check the top brass screw out of curiosity and it did have two small holes in the threaded part and one super fine hole ( size of a human hair maybe ) in the end of the screw hmmmmmmm figure I can poke all three holes out and see if they are open. looking at the one pic from the bottom you can see there is a brass part in the center of the tube but it does not have a screw head on it. what do you think I could be missing if I take the screw out on the top and work a fine wire though the holes? all other holes the are visible in the pics have had a wire though them but I am going to redo them since I have it off in my basement.

I ended up removing the top screw and running a small piece of wire though it. there were three holes around the screw and one tiny one in the bottom. did not seem like it was all the gunked up. I did remove the brass screw at the bottom of the carb. poked the small wire into the hole from the outside and it stopped dead. poked a couple times more and the wire broke though some build up. all of the other holes I sprayed a litle LC though them and it flowed well. still curious if the brass piece that is located in the middle of the tube needs to be removed. when I put a wire though it it goes up into the middle of the carb and moves freely. seems like I have covered all of the bases or do i need to find a way to gte the center part of out of the tube ?

 

[hemitom]

If you can pass the wire through that should be good enough, while the carb is off soak the whole thing overnight in kreen or whatever cleaner you have. In a pinch acetone will also work.

update to the snowblower starting issue. I put the carb back together yesterday in my cellar so I would have to do it outside. sprayed two short bursts of starting fluid in the intake before putting the carb back on. made sure all of the fuel lines were as straight as possible. prime it and it sounds different ( this is a good thing ) pulled the cord and whala .... nuttin , sis not turn over or even try to start .... hmm prime it some more and try a couple more times..... oh boy ! look and everything is good an tight but wait I notice that there is a little gas leaking , oh no a hose had a leak ? check and found that the screw holding the bowl on the bottom of the carb was loose ( I left it loose in order to line up the drain screw, looks like some knucklehead forgot to tighten it all the way ... that would be me ) tighten the nut and check for leaks all looks good. prime it up and pull the cord a couple of times ... nuttin ... on the fourth pull the motor starts put put put put put and progressive gets louder until it is at full throttle whew !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ran the unit for a good 20 min then took it off the porch to throw some snow around the yard. great news it is running again bad news for the snow lovers is we may not see any more snow the rest of the year since it is back up and running ....that is fine by me :O) now I have some spare parts and a better knowledge of how the unit is put together and how it works .thanks for all of suggestions and help everybody !

 

[itguy08]

Glad you got it running again!

I just hope we do get more snow - I love the stuff and also fixed our snowblower.

You may be one of the few people who is looking for more snow. I do not mind it as long as it is not sleeting like last Wednesday. people were driving way to fast in it . appreciate you and others taking the time to get me back up and running.

 

[itguy08]

Yeah last Wednesday was nuts. We were coming home from out near Pittsburgh and the 2.5 hour drive took us 7 hours.

I do love the snow but you can have the sleet and ice.

Did you figure out what was wrong though? Was it the last cleaning of the bottom carburetor screw?

I would say that 100% of the problem was the screw at the bottom of the carb ( main entry jet ) looking at the design the bolt that holds the bowl on fits fairly tight to the bottom of the bowl so the fuel has to enter the small jet in the screw to flow up into the carb. I am sure a little fuel would get in there enough to start it but it would quickly lose fuel and shut down. what sucks is I had the carb off a few times before this and did not notice that the hole was not open enough. lesson learned here for me was, I should have taken the carb off and down the cellar to work on it the first time. I did get it clean but somewhere along the line some more stuff came loose and ended up clogging that jet up pretty bad as I tried to start it more and more . it is funny now but at the time it could be frustrating if you let it, that the more I worked on it the unit started running less each time . patience and persistence paid off as it usually does we just need to keep plugging away, I suppose. checked the weather forecast and low and behold we will be in the 40's next week :O) hey if keeping my snowblower ready is all it takes to keep the temps warmer I am all for it .

Well done. A plugged jet probably would not have been covered by warrantee. You saved yourself some $.

I agree the dealer would have charged a crazy amount to fix the issue. good news I have some spare parts ( kept all of the parts that I changed out , other then the 1 gasket on the carb bowl )
