What happens when you open the throttle on a motorcycle?
Wide open throttle yields no power. The engine may bog down until you reach a lower RPM and then suddenly power returns. Spark plugs are clean – No residue. Insulator may be white. Runs better at higher altitudes – AFR becomes normalized due to reduced atmospheric pressure allowing fuel into the venturi easier.
What are the symptoms of lean carb settings on a motorcycle?
Cold starting and warm up. Reduced Power – Sluggish at certain RPM’s. Wide open throttle yields no power. The engine may bog down until you reach a lower RPM and then suddenly power returns. Spark plugs are clean – No residue. Insulator may be white.
What causes engine to run hot on lean idle circuit?
Backfires – Popping on deceleration for a lean idle circuit or backfires in general. Runs on choke – The vehicle may run on choke when it’s warm but stalls if the choke is turned off. Engine runs hot – Due to more oxygen than fuel combustion temperatures are hotter reflecting on a temp gauge.
Can a stuck petcock cause a motorcycle to hydrolock?
A stuck float with a standard petcock can create issues as the fuel will do what is stated above but when the bike is sitting. This fuel can also fill the cylinder and create hydrolock and destroy your engine when you start it. The piston cannot get to top dead center on the compression stroke and it bends your connecting rod. This is real.

Can a generator run at wide open throttle?
I am able to move the throttle on the carb freely, and the governor moves freely when i move it with my hand and will lower the speed, but if I let go it goes right back up to full throttle. there is noting plugged into the generator. Is this a governor that needs adjustment? the model is 919.327210 and the engine is a 10 HP tecumseh.

Why does my Traxx die at full throttle?
Click to expand… mine also bogs out and dies at full throttle but that’s ONLY if you give it full throttle. Also I’m not letting it warm up a little before giving it full gas could that be the problem?
What should I do about wide open throttle on my Boat?
Before getting too deep into troubleshooting, make sure that the throttle control at the helm advances the throttle lever on the engine from stop to stop. Wide open throttle (WOT) seems to strike fear into the heart of many boat owners.
What are the symptoms of lean idle on a motorcycle?

What are the symptoms of rich carb settings on a motorcycle?
Rich Reduced Power – It has less power but seems to be OK and runs. Reduced Fuel Mileage – Your using more fuel per cycle so your mileage becomes worse. Rough Idle – Combustion takes a just a bit longer with more fuel and at lower RPM’s the engine can idle rough.
Why does my motorcycle run less in lean conditions?
It’s created by high temperatures in the combustion process between nitrogen and oxygen. Although NOx is present in all exhaust it can be more pronounced in higher combustion temperatures associated with lean conditions with more oxygen. More oxygen=higher burn temp Reduced Power – It has less power but seems to be OK and runs.
What causes a motorcycle to have a rich condition?
Rich conditions can be created by people too but the condition is usually caused by: Installing a jet that is too large. Setting a float level that is too high. A Choke that is stuck or not turned off. A stuck float in the float bowl will allow fuel to overfill and then spill out the main jet into the venturi.
