Generac 4000 EXL Generator

The other day I noticed a a gasoline oder in my garage. It appeared to be coming from my generator. Upon closer inspection I noticed gasoline leaking from area near air filter. I also noticed I forgot to close the fuel shut off after use this winter. Gas was leaking from the carb. float bowl. Pulled the Nikki C1535 / C120012 carb. Cleaned the carb and float needle and reassembled. When reattaching the carb to engine I forgot the exact linkage position. This unit has 2 linkages 1. what appears to be regular throttle and 2. A small spring linkage which I thought attached beside the other linkage. When I started engine
it ran fine from idle but was rough when under demand or auto idle switched off.
I assume this small spring is the autoidle? I have some pictures on photobucket
I forget how to attach them. Below is a link.
Any thoughts or suggestions
Thanks
Rich

Hello Rich,


The spring in question (not for auto idle) goes in the same hole the link rod is in, It pulls tension between the carb throttle shaft and the governor arm to reduce slack and light surging.

It's easier to install the spring in the hole first then the rod.....


Good Luck

Thats the way I installed it so the rough running must some sort of gum or varnish in the carb. The rebuild kit is half the price of a new carb and it does not include any welch plugs. I quess its a new carb. Maybe I can find the welch plugs and really clean this out and keep as a spare. I am really begining to hate
this ethanol treated gasoline. It is evil on my small engines and create a maint. nightmare.
Thanks
Rich
