Briggs & Stratton

Well. We rebuilt our trottle cable, and we re-assembled the air filter. The group that checked this motor over installed an inline fuel filter. Anyway we finally granted this thing and it turned over. I did notice though that we weren't getting fuel into that filter. This thing has a mopar fuel pump installed... I think. So we tapped the brakes on our efforts. We are happy it simply wanted to fire. I'm going to call the shop that did the work.

So dumb question. Inside the air intake there is what looks like a flapper valve. It doesn't move in my case though, with the throttle. Is that normal?

The upper "flapper" is the choke plate, lower is throttle. An automotive fuel pump probably has too much pressure.

By any chance does anyone have a picture of the throttle body setup. Specifically how the springs attach to the throttle parts on the throttle body. My springs are missing and we have two new ones on order. I want to install them properly. Thanks.

RickM your pictures disappeared. Post a picture of your carb so we can see what you have.

Actually I muddled through it. I still however cannot for the life of me get this thing running. It seams that the motor is stabile but everything else is suspect. This is the order of our troubles.
1. Got throttle sorted, and every time we gave it gas it would die.
2. New spark Plugs, changed oil. Went to start and quickly fuel issue popped up.
3. Changed entire fuel hose lines, drained the tank and refilled with 93 oct. No fuel pressure
4. Put in a 1-2 psi fuel pump, and it runs but still no fuel pressure.

I am thinking I need to get it running possibly off an aux tank and then figure out the fuel line issue. This is frustrating as 1 step forward = 2 back.

you should probably pull the carb and give it a good cleaning, meaning tear it down and clean it internally, making sure all the tiny passages are open.

If all else fails and it doesn't want to run proper, and you have no clue, bring it to a larger lawn mower shop they could probably do something.
