Fly 150 hasn't been used in a long while. Tried starting it and it runs, sputters, and shuts off. I've tried removing the evap system and nothing changes. I've already siphoned the old gas and added fresh.
I'm stumped. Is there a fuel filter? What am I missing?

Not sure how big a job that is. I guess take things apart one step at a time.

If it's the carb version check the rubber intake manifold from the carb to the engine make sure there aren't any cracks in the rubber.

Moved from Project Reports to General Discussion, as this is a question and not a project report.

not terribly involved. a few basic tools and some attention to detail. some carb clean or brake clean and compressed air and you'll be rolling.

recommend upgrading your idle jet to a 38 if you're in there already.

double check your fuel and vacuum lines for deterioration and the intake for cracks. I'd knock a new air filter in at the same time.

quick afternoon of work while listening to the ballgame.

Does it sound like this? Mine turned out to be an exhaust issue.

What kind of basic tools are we talking?

screwdrivers, pliers and a tiny wrench.

specifically: you'll need a decent Phillips head, a small flat head for removing the jets, a medium flat head for the clamps securing the carb, a small 7mm wrench for removing the diffuser. the pliers are for removing the fuel and vacuum lines.

you'll need to blow the bucket out and possibly the body work to get there unless your a contortionist. so, plan some time on that. it's mostly screws and maybe a few 10mm bolts.

expect to burn a solid afternoon.

I already have the body off to remove the evap system. Bucket is the storage under the seat, I presume.
