TOPIC: Evinrude 4.5 help

Took my lil 4.5 tiller on vacation....
got it allset up...fresh gas...got'r running...
but as soon as u twisted to give more throttle it would just bog down and die...
It would idle all day long...
i switch the plugs out, cleaned the filter, and a few shots of carb cleaner....fired it back up...ran great....could rev it up seemed good to go..then went back to square one...
I took out the lean /rich screw ( for low speeds) and tried shooting some cleaner in ther too...

After that I couldn;t get nothing...a few pops (backfires) but that was it...

Motor hadn't been ran for 3 years....when stored it was fogged and drained...
Would like to get running again before winter and run it a bit and winterize it...

any ideas?

Check for fire on both cyl while running (below I have two ...puts on a great light shoe when testing after the sun sets)

The motor will run good on 1 cyl at low speeds

Coughing and back firing is a sign of running lean...Check carb...if you have a cork float you may have problems with ethanol destroying the float less you coated it

Remove carb, disaaemble and clean completely. Sounds like main jet is blocked

i know it has spark, due ot running previously before me spraying the carb cleaner

thanks...kind of what i was thinking from the start...
thinking by using the carb cleaner it may have freed up some other debri and now causing no fuel....plugs were dry... will try this out, or worse cse just drop off at marian that rebuilt the carb last time...

thanks...

It that motor a internal tank? I've seen a few where the in tank petcock filter was a gummed up mess. Just a thought if so.

no uses a remote tank

After the carb rebuild, add a clear plastic fuel filter to the gas line after the primer bulb. Keeps gunk out and gives a view of the gas flow for future troubleshooting.

thanks ..its amotor that doesn't get used often enough ... last time it ran was about 3-4 years ago...

thanks guys.

Pulled carb off and cleaned...replaced fuel line...
reassembled, hooked up the fuel and nothing....

Any ideas? the fuel bowl had reside, i cleaned, all orifices with carb cleaner and blew out inlets with air....put it all togeter, put in a garabage can w/ water,,,primed it up...and gave it few pulls nothing , not even a backfire? plugs looked/felt dry?

any tricks?

Anybody??? perhaps trip to the Marina?

If the engine did not even try to start and the plugs are dry, you most likely still have a carb issue. To confirm, squirt a little fuel directly in carb and if it fires now for a couple seconds you have a fuel delievry issue.
If you pull fuel line off carb and pump bulb, does fuel squirt out hose? If so, fuel is getting that far. If not there is an issue between tank and engine. If you do have fuel, carb has to be at fault. Perhaps not reassembled correctly? Inlet needle sticking?
Jet s still blocked? Did you remove all gets and look through them to make sure clear?

well if weather permits days off may try the squirting fuel to see if it pops.

thanks.
