Tom Thumb engine

[helix95]

I want to build a Tom Thumb.This engine is off two cycle single stage sno thrower.Found it in the ding weed along access road and it fired right up when I put fuel in it!It is a Tecumseh with a diaphram carb.Any of you guys in the snow belt could find one I am guessing.The shaft is a 5/8.:thumbsup:

Picked up ebay frame with similar shape as tom thumb.I am going to scale it down close to the size of plans.Engine mounts were made for this snow thrower engine.The bike will be 1" taller,1"longer and 2" wider.

I don't think that engine will fit too good in a Tom Thumb. Here's pictures of the one I built recently. The red bike is a 4" wheeled Bonanza BC200 for comparison. In the other pic it has a WB510 laying in it with a GoKart cycle frame sitting behind it.. My frame is 9" tall overall, making the engine bay 7-1/4" tall.
