III. Primer Bulb and Choke

In Temperatures above 40°F (5°C):

Follow instructions in Section B.I. See "I. Primer Bulb Only" instructions on page 10.

In Temperatures below 40°F (5°C):

1.To avoid carbon monoxide poisoning, be sure engine is outdoors in a well-ventilated area.

2.Move engine throttle control to “CHOKE” or “START” position, if present (see equipment manufacturer’s instructions). See Figures 23 thru 25.

3.When starting a cold engine, push primer bulb firmly 3 times, allowing primer bulb to return completely to original position between pushes. See Figure 22 on page 11. Afterward, continue reading instructions below.

NOTES

Be sure to cover vent hole when pressing primer bulb.

Cooler temperatures may require pushing primer bulb firmly 5 times.

DO NOT use choke or primer to restart a warm engine after a short shutdown. Doing so will flood the engine and may result in equipment malfunction

4.Operate equipment control to release engine brake or clutch, if present (see equipment manufacturer’s instructions). See Figure 23.

engine causing serious injury. To avoid this risk, carefully follow these instructions:

5.Grasp starter cord handle. See Figure 23.

a.Pull rope out slowly until you feel drag.

b.Without allowing the rope to retract, continue pulling rope with one rapid full arm stroke.

c.Return rope slowly to original position.

NOTE

Following the instructions listed in the steps above avoids potential damage to the recoil mechanism.

6. When engine starts:

1. “SLOW” Position

2. “RUN” Range

3. “FAST” Position

a. Momentarily move engine throttle control to “FAST”

position.

b. Next, move engine throttle control to desired speed

in “RUN” range.

NOTES

If engine starts but falters when engine throttle control is moved to “FAST” position:

a.Move engine throttle control back to “CHOKE” position.

b.Next, move engine throttle control to “FAST” position.

If engine dies after engine throttle control is moved to “FAST” position, repeat steps 2 thru 6 to restart engine.

4. “CHOKE” Position

Figure 25. Start/Choke Control Positions

7.If engine fires but does NOT continue to run, move engine throttle control to “FAST” position and start engine.

8.If engine fails to start after 3 attempts in the “FAST” position, move engine throttle control to “CHOKE” position and start engine.

9.If engine does NOT start after following steps 1 thru 8, contact your Authorized TecumsehPower Servicing Dealer. DO NOT attempt to start or troubleshoot this engine in any other way.

OV195XA, OV195EA specifications

The Tecumseh OV195XA and OV195EA engines are notable members of Tecumseh's extensive lineup of reliable and efficient power products. Designed primarily for outdoor power equipment, these engines cater to diverse applications including lawn mowers, generators, and other small machinery. Both models are characterized by their compact design, robust performance, and user-friendly features.

One of the standout features of the OV195XA and OV195EA is their powerful 195cc displacement, which delivers a significant amount of torque for heavy-duty applications. The engines are equipped with a reliable overhead valve (OHV) configuration, enabling better combustion efficiency and improved power output. This design not only contributes to higher performance but also leads to enhanced fuel economy, an essential aspect for users looking to maximize efficiency.

These engines also incorporate a lightweight aluminum die-cast crankcase, which reduces overall weight without compromising strength. This material choice provides durability while making the engines easier to handle and install. The dual-element air cleaner enhances the engines' filtration systems, ensuring cleaner air intake and prolonging engine life by minimizing wear and tear.

The Tecumseh OV195XA and OV195EA engines are engineered with a focus on ease of maintenance. They feature an integrated fuel tank, allowing for quick and convenient refueling. Additionally, the side-access oil drain simplifies oil changes, making it easier for operators to maintain the engines without requiring specialized tools.

Another important aspect of these engines is their low vibration and noise levels. Designed with advanced technology that minimizes both sound and vibration, the OV195XA and OV195EA provide a more comfortable user experience, especially during prolonged operation.

In terms of starting, both engines offer easy recoil start mechanisms, ensuring that users can quickly get to work without the hassle of complicated starting procedures.

Overall, the Tecumseh OV195XA and OV195EA engines represent a blend of performance, durability, and user-friendly design. Their innovative features make them suitable for a broad range of applications, ensuring that they can meet the demands of both professional landscapers and DIY enthusiasts alike. With a focus on efficiency and reliability, these engines continue to uphold Tecumseh's legacy as a trusted manufacturer in the small engine market.
