HS50 Flywheel

[FloridaMiniBikes]

Does anybody know if other Tecumseh flywheels can be used on a HS50 and if so,
part numbers?

 

[markus]

what year engine/crankshaft are you using.

Gonna use a NOS Shortblock: Engine # SBH-4277B Part # 754277B.
3/4 on the output. will have to measure the flywheel side.

That looks like the later external CDI motor.

I have flywheels on the parts for sale section. If any if those will work you can have one for the price of shipping!

Thanks Carplay, and hey Ole, what is an external CDI motor?

 

[bikebudy]

Two mounting posts up in the Cyl fins is for CDI Coil, so no points.

Magneto are on the inside cdi is on outside of flywheel. Cdi requires external magnet on tht outside of the flywheel.

611029 for the points version and 611080a for cdi/electronic ignition.

Thanks Markus, that 611080a, is that the same flywheel on these 3hp Tec Side popper engines? Got 3 or 4 of em in the shed.

Yea, They started to simplify production with the larger taper and all the small frames got the same parts. You can actually rob it all from one of those, You'll need the extension studs for the coil, the plastic spacer on the crankshaft, etc.. The shroud, backing plate, cup screen will all cross as well.

If you are lucky and have a 1985 to early 90's version to rob parts from, it will have the old school recoil on it instead of the fan type recoil which makes it not as noticeable that its a late model :wink:

I used one of those shrouds on this 1994 that had a fan recoil originally:

Let me know if you need a shroud like the one in the pic. I have one of those with the studs installed instead of rivets

Thanks Markus and Carplay. I just did a review and one of my H30's has an HS50 shroud and recoil.
