Ok, after my last post in the other thread I pulled valve cover and checked valves . A few thou over so I readjusted. The manual said two marks on the timing belt wheel would be parallel to the block at TDC. Didn't see any such marks so I used a straw in the plug hole.It ran just the same, it died if I opened the choke and ran with it partially closed.I researched further to make sure I had right carb gasket setup. I removed and disassembled carb once again. This is the new carb that I bought. Blew everything with carb cleaner and air. I used a new gasket between block and insulator and a new air guide gasket between insulator and carb. Back together and it runs perfect again. Fuel lines are new so maybe I will flush the tank.
I'm still a bit confused on engine number.
I am pretty sure it reads GJARA 198.....(paper downstairs) S3AI. There is definitely a character after the S3A. It's like this .

This site
http://www.hondalawnparts.com/pages/oem ... and=HONENG has good choice of models for lookup but I find S3A only in both GJAEA and GJARA series but never with a 4th character.
Google at one point showed a link with S3AI to a no longer available ad on kijiji so someone else is reading like me. If the I means nothing for parts lookup then what purpose does it serve?
