    Thermostat housing hole.

    can make out the number on the jet it’s to screwed up. It is the middle carburetor. The company that I corresponded with told me it was a 120 but Yamaha discontinued and said I could try a 125. Here’s the float on #1 carburetor. I should be able to compare it with at least one more today when...

    Sounds like the float is about right then. I guess cleaning that seat gave it room to sit lower. I’ll look at it again and get a picture . Carburetor 2 has the screwed jet. I’ll get that number. Been freezing out the last few mornings and I got honey do’s as well but I’ll be out there soon. Have...

    I just came in. I’ll look at one of the other jets for that number. Got the top carburetor ready( the easy one) except for waiting on the new o rings. The float is sitting lower than it was when taken apart. I don’t have the specs but I measured them before removal. How do I adjust? The screw is...

    Been using Seafoam and also did their decarb method. Most of the jets are open just looking bad and discolored. Even the ones with gunk in the tube and bowl . Nothing is used but non ethanol fuel as well since I’ve had it. Sorry for the double post back there.

    Thermostat housing hole.

    Just found out Yamaha has discontinued the jet with the screwed up head. I can leave it and hope for the best or try the next bigger size which means I may have to replace all three ( not in my budget right now). Since the motor ran good but leaked fuel . I’m considering leaving it for now and...

    Thank you,thank you. The kits don’t come with any jets except the pilot and the nozzles are not even available anywhere for this motor. Besides there was a kit put in it about a year before I got it. Pilot jet,float and needle still look new. Its abvious it was not taken apart and cleaned...

    I’m using wooden skewer and cotton to make a big q tip and toothpaste. I just ordered a carburetor cleaning kit with nylon brushes. Will be here tomorrow or should I stick to the skewers at least where the nozzle cavities are? Will polish the nozzles and and jets with toothpaste. Don’t know what...

    Thermostat housing hole.

    I think I can put a screw with a nut in that spot. I’ll look and make sure. I just came in for a break. Been working on the first carburetor polishing the seat with tooth paste. They’re pretty bad so it’s taking a while. I can see the difference between it and the others now. They’re almost pin...

    Yes sir. I think water wicked into the threads maybe. One squeaked the whole way out while unscrewing. Lol What are your thoughts on the missing screw from the bowl? Someone stripped the threads out completely.

    Good morning im headed back out to the shop to clean and micro polish everything so I’m ready for the new gaskets when they arrive. I have a screw extraction kit I’m thinking about for that jet. I’ll be hitting it with some spray all day while working on the other parts before I do anything. I...

    Sorry I was so busy with a rant. Will it hurt to soak the jets or should I blow them out with cleaner and air and then polish?

    I opened up a can of worms today. Pulled the carburetors and got started. The top carburetor which didn’t leak near like the other two. When I opened it up that bad gas smell hit me. I had no idea there were that many places for it to hide and just sit in the carburetors. The needle and float...

    I’ll definitely report my findings. Got my caliper for the pilot screws. I haven’t started yet but noticed the bottom carburetors pilot screw seems to be in pretty far as the spring looks like it’s really pushed in to the point of bowing out some. Hopefully there’s nothing wrong with that...

    Finally getting my ducks in a row so I have time to start on the carburetors. Couple of questions sir. Is it ok to leave in the seat while cleaning the carburetor body, then micro polish? And after micro polishing do I flush out the toothpaste residue with some spray cleaner?

    Thermostat housing hole.

    After I ran it today I could see fuel slowly coming out of all three throats and running down the sides. So it would seem the o rings are ok. Man I hope a thorough cleaning will fix the problem. Still planning on replacing at least the float gaskets . I’ll let you know what I find when I open...

    Thermostat housing hole.

    Good idea. I’m going to run it again today in a tank. One- it was on the muffs the other day and at idle got hot to the touch but when I raised the rpms a little it cooled down. I’m willing to bet it does fine in a tank since it acted the same way on the muffs before the old thermostat stuck...

    Thermostat housing hole.

    Yes sir, fuel is in the throats and around the outside . Thought maybe the top gaskets (o rings) leaking. It’s hard to tell where that came from. I want to pull all three and work them over so I’m not doing this every month. Especially since I’ve replaced everything else but the fuel pump with...

    Before we started Christmas I had pulled the drains again and this time flushed out the carburetors with the bulb. Seemed to help the next day so I ran it on the muffs and checked for water leaks etc. Motor ran good. I checked it this morning and found a little fuel in the throats of the middle...
