Tech Notes
 
NOTES FROM OUR TECH DEPARTMENT
  This is the Tower Hobbies .25 cu in (4.1cc) Car Engine with Pull Starter.

FEATURES: Dual ball bearing-supported crankshaft ABC cylinder and liner construction-"A"luminum piston,"B"rass cylinder liner that is "C"hrome plated Slide Valve Carburetor Purple anodized heatsink cylinder head SG (pilot) type crankshaft Two year limited warranty

INCLUDES: Tower Hobbies .25 cu in (4.1cc) Car Engine with Pull Starter, Glow Plug, Exhaust Gasket and instruction sheet

REQUIRES Fuel: 2-cycle glow fuel with 20% nitromethane, 16% lubricant- Most of the fuels we carry meet or exceed the lubricant content required for optimum performance and maximum engine life. In the past, the conventional lubricant content used in fuel was 18%. But with new advanced technologies, fuels like Red Alert and O'Donnell for example, have a better quality of lubricants even though the percentages of lubricant content are lower. These high-tech lubricants provide exceptional cooling and protection. NOTE; Do not use a fuel with a nitro content higher than 20%

SPECS: Displacement: 4.11cc (.25 cu.in) Bore: 17.94mm Stroke: 16.4mm Practical RPM: 3000 - 42000 Output: 2.5bhp/34000rpm Weight: 13.2oz (374g) Distance Between Mounting Holes Same Side: .83" (21mm) Distance Between Mounting Holes Opposite Side: 1.4" (37mm) Length from Starter to Front Bearing: 3.4" (86.8mm) Height from bottom of Crankcase to top of Head: 3.9" (99mm) Height from bottom of Mounting Tabs to top of Head: 3.3" (85mm) Width of Mounting Tabs: 1.8" (44.8mm) Diameter of Exhaust Outlet: .73" (18.5mm) including gasket

Carburetor Needle Settings- High Speed Needle: Pre-set for break-in at 4 turns from closed, set 2 - 3 turns from closed after break-in Low Speed Needle: Pre-set 3 turns from closed break-in Throttle Stop Screw: Approximately 1mm from fully closed Mid range needle - Flush with the outside of the body

COMMENTS: Some notes on Slide Valve and Rotary Carburetors: Rotary carbs offer a larger response in the middle of the power band. This works well for off-road applications when throttle response must be varied. Slide Valve carbs provide greater response at the beginning and end of the power band. This works well for on-road and racing applications for fast take-offs and high speed.
