Webra T4-60 Custom
 
Here is my latest customized engine. The Webra T4-60 was a unique design for it's day. Definitely out of the ordinary compared to all the other four stroke engines that were around in the 1980's.

This engine was locked up solid with dried castor oil residue, and so I overhauled it and painted and polished the various bits.

great job! did you have to replace the piston? I hope it runs as nice as it looks. so this goes in the beater bird?

Thanks Bruce. :)

No, this is not for the beater bird, lol.

The piston was okay. I replaced the bearings, the crankshaft key and prop driver, the prop nut, and all bolts with new stainless steel versions. And I hand made the rear cover gasket.

I painted the entire engine, and then after it was cured I scraped the paint off of the fins edges and then polished the edges.

I polished the intake port on the rotary valve. I polished the combustion chamber in the head. I polished the carb body, the carb intake tube, the exhaust header, the muffler, the prop driver, the prop washer, and the belt drive pulley even though it is hidden by the belt cover. I know it's shiny, lol. :p
