(bogging) reeds?

[Diesel Spree]

1993 elite 50 boggs when you give it throttle. scooter ran then sat a while, and then i got it cheap. rebuilt the top end and now trying to get it to run.

it starts. and sometimes idels well but some times it wont. some times u have to use starting fluid, and some times you dont. it boggs when you give it throttle but if you can get the rpms up it will run wide open good but if you let off then get back on it will bog. and die normaly.

i think it is starving for fuel. there is always fuel in the bowl. and im about 99% positvie the carb is clean.

so i am wondering if the reeds would have anything to do with it? they have a small gap in between the reeds and the cage but they r not broken or cracked. ???how do u tell if the reeds are worn out????
?????should they sit flat against the reed cage?????

thanks

You are right, a bent reed might be the problem. Actually it mght be the pilot fuel jet being clogged or the air jet out of adjustment. The pilot fuel jet is extremely tiny.

Be sure to put gasoline in your scooter. Diesel won't work
Good luck

Yes, reeds are supposed to sit flat against the reed cage.

Also, starting fluid + 2 strokes is a no-no ( a diesel guy like you should know better than to trust that stuff ).

[Diesel Spree]

ok so the reeds might be the problem? is that comon simptons of bad reeds?

and ya i dont like to use the starting fluid but i want to get it stated

[devenex]

Well either way if theres a gap you want to fix that.

Bad reeds will affect starting and low RPM performance. Theoretically the reed is supposed to be open all the time at high enough RPMS, so gaps obviously stop mattering.

One note: I haven't experienced any of this personally, but have picked up a lot in previous threads about bad reeds. Oh, and I stayed at a Holiday Inn Express last night

Actually as long as the reed is parallel to the reed block and the opening is no more than a few thousands it will not be a problem. The pressure in the crankcase will close the reeds as long as they are not bent (twisted). Oh and at higher engine speeds, reed don't ever close (not enough time to open and close). Also they can't be causing your issue as the issues would be consistant if it was the reeds. You are right the engine is lean. You have a carb issue, pull it and clean it.

Did you make sure to see if light comes through that tiny hole in the carb bowl? You should . Sounds like pilot is clogged as BEAR said...not enough fuel in carb bowl, then when you give it throttle it uses the small amount of fuel that is in bowl and your done

[Diesel Spree]

i no its geting fuel to the bowl because while its running i can open the drain and fuel will run out. but ya i will clean the carb. again cant hurt anything.

and on the mixture screw it should be at 1.5 turns out? and does turning it out richin the mixture?

But....is it getting enough? Doesn't sound like it. Turning the mixture screw in richens it up.

[Diesel Spree]

so you think the problem might be its not getting enough fuel in the bowl?

[Bear45-70]

so you think the problem might be its not getting enough fuel in the bowl?

Just because there is fuel in the bowl, doesn't mean there is enough. That is why there is a float setting specification. You need to check how much fuel is in the bowl.

There is an easy way to check. Put a clear hose on the fuel drain nipple, hold the hose in a "U" shape up along side of the carb and open the bowl fuel drain screw. The fuel will rise in the hose to the level it is in the bowl. If it isn't about 3/4 of the way up the bowl your float level is too low.

Now if there is enough fuel you will need to clean the carb, paying extra attention to the itty bitty idle circuit passages. The set the mixture screw about 1/8 ti 1/4 richer than spec.

The reason the idle mixture has to be rich on these little carbs is that there is no accelerator pump and to transition for the idle circuit without a bog, the idle mixture needs to be rich enough to carry the engine until the main fuel system starts flowing fuel.

ok its getting enough fuel in the bowl i did the test.

so i took the carb apart and cleaned it again but i am wondering i the poilt jet is is a perminent one, and should you be able to see threw it?

i think it might be plugged because i can not stick a needle threw it or get any carb spray to spray out the top????????

No, you can not see light through the idle jet hole. It is somewhat doglegged. But if you can't get carb spray through it, you've found your problem. Bogging is classic example of the hole not being clean.

How to clean? Gunking is not the answer, and you can't push hardened varnish out with air pressure. Best way is to dig at it with a #13 guitar string, and carb spray. Don't be weary. It is painstakingly slow, alternating between the spray and guitar string.

Guy, go wash your mouth out with soap!
