The jets/passageways in the carb are likely plugged with bad gas, hence it will run with the choke on. Common problem with the 10% ethanol gas.

Changed oil clogged air filter with new after market air filter bike ran good until the third time I started it it would not idle unless it was choked


My Harley is very slow to warm up, it also does not like to idle without choke unless it is good and warm. It could be the clogged filter was acting like a choke, but ruining your gas mileage. Now with air flowing smoothly the engine needs a bit of choke to idle. It should not need choke once it is fully warmed up unless your idle speed is set too low. With the engine hot, check RPM if you have a tach. If too low, adjust the idle speed at the carburetor. I suggest you find the adjustment while the engine is cold.

Idles with 1/2 choke. If open choke, or throttle - engine dies without any RPM spike. Carb was cleaned, jet is clean. When idles, there is gas in the primer bulb.


Hi, Andrew and the usual suspects are:

1. Fuel cap or fuel tank is not venting properly.

2. Fuel filter clogged.

3. Fuel line pinched or kinked.

4. Float needle and seat sticking.

5. Float level too low.

6. Carburetor bowl vent line clogged/blocked/pinched.

7. Idle adjusting screw set too low.

8. Air/fuel mixture screw set too lean.

9. Idle port, transfer ports, slow air jet clogged.

10. Slow fuel jet clogged.

Backfires when choke is on, but almost dies without it when idling


I would check the jetting to be safe but it could also be dirt in the carb. The main jet has very little to do with lower engine speeds and especially idle. That is controlled more by the pilot jet and circuit. Your best clue is how it responds when you add more choke. If it gets worse then there is a rich condition but if it gets better then you have a lean condition. From what you have described it sounds like a lean condition.

Have new 450 and is very difficult to start. Lost or didn't get book. How do I start it and re-start it while still warm??


Start procedure is, push the primer as many times as it takes to 3/4 fill the bulb ( you cannot over prime it ) pull the blue choke lever fully out,place the saw on the ground with your right boot through the back handle, crank the engine until it fires once, do not continue to crank the engine with the choke out ( they will not run on choke, only fire ) push the choke fully home, crank the engine until it starts, blip the throttle trigger to bring the saw to idle, warm engine, pull the choke fully out and push in again without cranking engine, this will engage the part throttle, crank the engine until it starts, blip the throttle to bring the engine to idle.

Bike wont kick start or idle , it will coast


first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.

Sounds like the battery may be weak, recharge and test, maybe replace. As far as starting, most Hondas will not start if you open the throttle any at all. Shadows being liquid cooled are generally cold natured, but you should be able to ride away with the choke on in 1 or 2 minutes, you might have to ride as far as 4 or 5 miles at highway speed before you can take the choke fully off. If it is taking longer than these times, you will need to remove and clean the carbs. the low speed jets may be partially blocked up.

If your bike has ever sat for more than a few months at any time, the carburetors could be plugged with gasoline residue. If so, they will need to be disassembled and cleaned.
Otherwise, make sure all of the normal tune up items have been performed; valves adjusted, air filter, spark plugs, etc. And make sure there are no air leaks between the carburetors and the engine.
Finally, if the above things are all good, then I would perform a compression check. With the throttle held wide open, you should see at least 140psi of compression, on every cylinder. Anything lower than that will cause an erratic idle quality and overall poor performance.
