Husqvarna YTH21K46 Motor Swap Done. Need Throttle Cable Advice

[JonnyBlaze]

Found the th throttle cable from the L120 I took that blown motor from. Looks like it will work. Just need to pick up a universal choke cable.

Here is a video.

Something good to know...... I saw in your pic you have this brand of fuel line..

... I sure as hell WON'T use it, how would you know if the inner liner collapsed ?? NO, NO, NO .....

Bought a new choke cable at NAPA and had to cut it up and use it to modify the original cable as the L120 cable was still too short. So that worked out great. Now I got go get another choke cable and hook that up. Already found the perfect spot.

Ok, so today I got the choke cable on and took it for a spin. Now its surging a little bit and runs fine with the choke out about a quarter of an inch. Then it coughs once when I turn it off.

Sounds to me like you have a carb. cleaning or O/H ahead, some of the Briggs Twins used a Nikki 2 Bbl. carb. and some used a Nikki 1 Bbl. carb., (Taryl fixes all on Youtube) has some excellent videos on the procedure, WARNING : if you go into the carb, Pictures FIRST, and remove Float bowl carefully.. DO IT UPSIDE DOWN... as these carbs have a habit of dropping the tiny main jets into the bowl SEE VIDEO'S and if it has 2 jets, one is left and one is right here's a couple vids on the 2 (TWO) Bbl. I don't know which you have ..The 1 Bbl. carb. has a fuel bowl Assy. ....... quite the same as the Nikki carb. used on a Briggs (med. HP) SINGLE cyl. eng.

Well all fixed! That was easy. Noticed a bunch of gas on bracketry under carb. Pulled carb off and removed bowl and was spotless. Plugged the fuel cutoff solenoid in and didn't budge. Tried plunging it with carb cleaner and needle nose pliers and that didn't work. Luckily I had a few spare carbs laying around and took one of the solenoids off it. Put it all back together and runs like new!

Only concern I have now, any chance I might have gotten gas in the oil since the carb was flooding out? New oil so dont want to change it if I don't have too. I can't smell so I can't tell.
