The engine started to do his and finally has got where it will never start cold without starter fluid...any suggestions on what is causing this? I have good flow of fuel... I've cleaned spark plugs but I will replace just to make sure... new air filters... new oil...what could this be? Thanks...will spark plug gap affect this?

Is the choke fully closing...???
What condition are the sparkplugs..??
If one is darker than the other...check your compression...normal is 160 to 180 psi..

Choke is fully closing... one plug may be slight darker than the other... motor only has 350hrs. As well

There are lots of things that can cause obstructions in carbs...
Dirt..fuellines deteriorating..varnish...just to name a few...
If everything else on your engine is correct..and you don't get enough fuel to start the engine when you apply the choke..
Its probably some bad joo joo in the carb....

Remove the carb...spray brake cleaner thru everything that looks like a hole..
Don't spray anything that is rubber..they don't like brake cleaner..
