zenith /bendix carb

I have a 135 with 3 cyl gasser and I took carb off cleaned it and noticed there is no adjustment on the bottom jet, the only adjustment is on the top right for I'm assuming idle? But the tractor stumbles on throttle and picks back up I'm thinking it's a bad coil but didn't know if it was normal to just have a plug where the bottom jet is.

You are right, the idle adjustment is on the top. It is normal to just have a plug where the bottom jet is. Take the bottom plug out and above it is the jet assembly. My question is did you remove it and clean it ? A complete parts break down is available on the free AGCO online parts web site.

you can search the archives here for past threads on this. Yes, change that coil, but don't expect a smooth v8 performance. This is a 3 cylinder diesel converted to burn gas. It will not bog down like a diesel, and it won't roar like a Continental 4. Even after you super tune it, time it, it is still an odd number, never smooth. mine coughs, and gasps as I throttle up, an up is rarely impressive. But it is a machine, and does what it is expected to do- just not the way you'd assume it would. Mine was a lawnmower at a golf course, and it mows my lawn as good as ever- and as fuel efficient as a one cylinder rider. It will take some patience and some getting used to, but it's nice to have it around.

Ok that makes me feel alot better! I guess I just didn't exactly know what is normal for it but sure makes me feel better getting some input from someone who has the same tratctor, I'm just gonna be doing light brushogging and pull a little 5 ft disc for food plots, just wanted to try and get it in tip top shape before working it to much.
