Sorry to not keep everybody informed especially after all the replies I received. Please accept my apologies.

Nothing has changed since my last report. My friend, {customer} had to take his trike for the weekend to use it and my son took the other one.

I now have my good one back and when I get the chance, in other words when the two bad ones come back, I intend to put the good carb on them to see what happens. This might be a while. I am still open to idea`s as I still don`t know what to do with them. I do own a sledge though.

Will keep you informed.

is the choke cable routed correctly, sometimes it gets slightly pulled ,causing the choke to be slightly on, making it run too rich and stall when warm, this happened to me, maybe to you too?

[Tri-Z Pilot]

Yeah, where the cable connects to the carb take it off and see if the cable return spring is rusty, if it is, your choke will stick thus making your bike run richer, I have seen this happen on a raptor before, put a new spring in, and it ran great. Good heads up on the choke cable wolfspider, I never thought about that.

I had a problem like this with my 110, easy peasy fix!
Take the slide out of the carb and take out the needle from the slide.
Then take the tiny clip off the needle noting witch notch it was in and put the clip back on ONE notch above where it was.
See if it idles any better after that, you may need to adjust the idle screw a bit, if it gets a bit better but not good enough move the clip up another notch, (assuming the needle has 5 notches and not 3) usually they are on the middle one, as the jet gets worn through use it gets bigger, thus making the mixture rich, by lowering the needle you lean it off again.

Yes the choke cable could possibly be a problem as they are difficult to replace with very little room to move around. The cable could have nipped on the inside.

Never thought about the choke return spring sticking or being weak. I did replace the whole choke starter system on our own last year just after we bought it. I do have a little free play in the cables up by the choke lever.

My next move was to lower the needles when I get them back next week.
Right now they are both in the second groove from the top. I am going to put them in the top groove after I try my good carb on them to confirm that it is a carb problem. I am sure it is. It has to be a gas problem because they run and sound great when the gas level starts to lower in the carb.

Thanks Guys. :-D

:-D Well just an update as to what I have done.

Happy to say I have my own sorted out, I hope.

I lowered the needle one notch, clip on the top, and adjusted the mixture screw 1/2 turn in from stock. Runs and sounds a lot better now.
I never thought about it befor but I will check the color of the plug tomorrow to make sure it is not too lean.

I havn`t got the other one back yet but it is too good to be true for the two of them to have the same fix.

Thanks again guys for all the advice. :-D

:-D Hooooorey Found the problem with the other one.

Customer came back today saying it was getting worse.

I pulled the carb again, removed everything and blew out all the passages with the compressor. As I was putting everything back I noticed a very small lump on the end of the choke needle. I flicked it off with my thumb and cleaned it up. This must have been holding the choke open very slightly but enough to cause all the problems. :oops: As he left he said it never sounded so good. That made my day. :-D

Just goes to show what a tiny speck of dirt can do. :evil:

Thanks again guys for all the tips and suggestions.

Merry Christmas to you all, "From the rock in the Atlantic" :-D
