Cannot start tiller - GX31 engine

12 years ago

I have a Honda Harmony FG100 Tiller, with 4-stroke GX31 engine

It quit running last spring when primer bulb got cracked and allowed air.

When I replaced primer bulb, I've been unable to start since.

What I've done:

=====================================

Replaced primer bulb

Replaced gas lines (to and from carb)

Replaced spark plug

Tested plug against engine cooling fin, I do see a blue spark

Rebuild carb with kit (Walbro WYL model)

About every 1000 pulls, I've got a burp-fire, but no continued fire or run

Tried starting with spoonful gas in both (1) carb and then (2) spark plug hole, no fire

Tried starting with carb spray starter, no fire.

I removed exhaust cover, so when pulling start pulley, I feel air come out exhaust / spark arrestor, but I also feel and hear air come back out the carb.

I'm at wits end.

Any ideas?
