Husky 22 Ton Splitter NO START...

Hey guys,
I've had this splitter for one year. Bought it last year. It's always had issues when starting. The same prime it 5 times (3 recommended). It fires and dies. Fires and dies. Over and over.... but I've always been able to get it starte till this week.
it has good fuel in it. I've pulled the bowl. Float is free and gas poured out. Put back together. Checked the gap on the plug. It was a little closed in. Gapped it to .030. All I get after it fire one time and shuts off is backfire through the carb.... help if possible.... Thanks Mark

This is a flat head motor. It's like the valve seat has came loose or something. I can't find my receipt so I doubt Tractor Supply is doing anything for me...
thinking about going to Harbor Freight and buy a over head valve engine for $119 and use a 25 off coupon. This thing has ticked me off....

I've been through priming it as much as 10 times. That same run for 5 seconds then it shuts of.
I've running carb cleaner through today. You can't adjust the timing on these motors. To me it seems the timing is off. Back firing through the carb...

Thanks. All ready meaaured.

No fuel problem. With everything I did and getting no favorable results... I googled the motor one last time. A guy mentioned on some forum that even though his spark plug was clean and gapped right. He replaced the plug and it fired up. He said that he had heard somewhere that champion had had a problem with that particuler plug. So I went and got a Champion 5861. That's what cross referenced from the original plug. It has a smaller electrode.
Put it in this morning. Fired up the first pull and ran great.... Go figure.... Stripping this thing apart. On the verge of trashing the motor thinking it was a timing issue. Plug looked fine... But oh we'll... lesson learned.

The plugs.

No on contacting Husky. I'm sure I would need to contact Speeco. They are the manufacturer I beleive.

As far as the carbon goes. It has always been tough to start. This go round. I flooded it non stop trying to get it started. Hopefully I have no more problems.

Just for some folks that may not know. I found replacement Briggs motors pretty easy for $169.99 or you can use the Harbor Freight (Honda) clone motor with a 25% off coupon for around $88.00. Same bolt pattern, same shafts size and you would just have tie off the brake shut off because of it being a lawn mower motor.
