Initial Trouble Shooting
The first step in diagnosing an engine problem is to
perform the periodic maintenance. A majority of the
poor run or no start conditions will be solved just by
doing the required maintenance. After the periodic
maintenance is done:
1. Drain and inspect the fuel from the fuel tank:
• Look for water.
• Look for dirt.
• Look for discoloration.
• Sniff carefully to see if it smells like varnish.
• Save a sample to show to customer.
To check the fuel in the carburetor:
1a. Get a plain piece of paper.
1b. Divide it into four sections and label them:
• Plain gas
• Two cycle mix
NOTE: Even for a 4-cycle engine, check for oil in
the fuel to see if the customer put motor oil in the
fuel tank.
• Gas from carburetor
• Straight oil
1c. Get a sample of fuel from the carburetor and
pour it on the section of the paper labeled
sample from carburetor. See Figure 3.1.
1d. Place a sample of two cycle mix where it
says two cycle mix, straight gas with
straight gas and straight oil with straight
oil. See Figure 3.2.
