I worked on my WYK-58 install yesterday.
An adaptor for a WT-butterfly-style carb was ordered from partsforscooters.com It is a simple .125" thick aluminum plate with intake port, pulse hole and bolt holes. It included two paper gaskets and two bolts, cost me $16 with shipping.
Darn, the adaptor won't work on the TLE43 engine, even if I used the WT carb.. This engine's manifold is dual-port/over-under like a shotgun rifle's barrels. The adaptor bolts directly onto the mani, but its port and pulse hole don't line up with the engine, not even close.
The manifold's top port feeds gas mixture to the engine thru a single reed valve. The bottom port is a straight shot of air thru the engine block to the piston.
I need to fabricate a TALLER thicker adaptor and drill it to match carb, pulse hole and manifold. The adaptor will also block off the lower port completely.
THENNN, instead of fabbing an external pulse line, I groove a passage from the adaptor's pulse hole to the 13mm(?) air port that matched the original carb's 13mm(?) air port.
That way the original manifold is left intact in case I reinstall the stock carb.
It SHOULD work.
