Troubleshooting
Below you will find a list of common issues we have encountered with new engine installations. If you do not see your problem or cannot
resolve one of these problems please contact your dealer for more information.
Engine Won’t Start
Common causes:
1.
No fuel supply.
2
. No spark.
3.
Engine has been flooded.
When trying to start the engine for the first time, and it is difficult, you need to verify that you have compression, fuel and spark. If you remove
the air filter cover and give the throttle 1-2 full turns prior to starting you can see if the accelerator pump is working properly and that fuel is
being delivered. Please refer to the Carburetor manufacturers instruction on how to set the accelerator pump. After you give the engine a few
squirts from the accelerator pump, give it a full enrichment or choke for best initial starting and do this
with the throttle closed.
Do not keep
twisting the throttle if the engine does not start. Stop and evaluate the problem or you can Gas Foul the spark plugs. If no spark is present
verify all connections and contact the ignition manufacturer for technical help.
Break-In Service and Hardware Re-torquing
With a new engine we feel the first oil/filter change should occur after the first 50-100 miles and all cover bolts and engine-mounting bolts
should be checked for proper torque. Keeping your engine oil clean is very important to the overall life of the engine. During the Break-In, or
look at it as the “Wear-In” period, engines produce very small metallic pieces that need a good filter to remove them. We do not recommend
extremely fine 10-micron filters during this time as they can clog quickly and begin to by-pass oil instead of filtering it. Use the 40 Micron
Filters during break-in and for the life of the engine. Ultima

recommends Ultima
®
Oil Filters, some examples are Midwest part#
25-78 & 25-79
.
Checking cover bolts and engine mounting bolts is just good preventative maintenance during this period.
Dyno Tuning
After your engine’s break-in procedure has been strictly adhered to we recommend that you have your engine dyno tuned for optimum
performance and reliability. Typically a new engine will have different fuel demands than an engine that has been through the break-in
procedure and additional tuning may be required for optimum performance and reliability.
