Installed new Nikki carb. Engine runs as if too lean while spitting and governor pulsing. Air/fuel adj needle has no effect either fully seated or removed. Runs smoothly if choke is roughly 3/4.

Sounds like you have an air leak and all the air/gas going into the engine is not going thru the carb. Remove the carb and re-check everything. Hope this helps.

Why is my exzaust glowing red why will it only run on choke?

To be only running on choke means there is not enough fuel on normal setup and choke allows more fuel to be passed, either a fuel blockage or mixture needs adjusting!

95 suzuki 250 quad king, at full throttle it runs at half power, choke seems inop

First make sure your choke circuit is working. May be an indication that your carb needs to be cleaned. I wouldn't replace it yet= clean it. If the choke circuits and the carb check out fine. An unresponsive motor/ carb usually means bad valves or valve timing. Example: it runs rich, spits fuel out the carb no matter how lean you set it. Even with the idle air closed it runs rich... intake valve is not closing or closing late. In that case it needs valves serviced.

I have a 1982 yahmaha xz 550 and it wont idle and it spits and spudders

Hi, Ld and the usual suspects are:
1. Idle speed improperly adjusted.
2. Air fuel mixture screws not properly adjusted.
3. Inlet system air leak.
4. Leaking accelerator pump.
5. Loose low-speed jet.
6. Plugged low-speed jet.
7. Contaminated or plugged low-speed circuit.
8. Enrichner valve/choke not seated or leaking.
9. Multi carburetors out of sync and need to be balanced.

5.5hp that only runs on choke, carb is clean,

you have an air leak some where. try spraying carb cleaner around the carb, if it starts to choke out further then you found it. but it can still be the carb even thou it looks clean the circutry of those carbs is so complex that a grain of sand can cause this issuse

Tractor won't run

If it is spitting black smoke, it is getting too much fuel. Try taking off bottom of carb assembly to get at the float. Make sure that the float doesn't have a hole in it and that the needle is in place

Spitting and sputtering

mine did the same, I found out that the high speed jet was clogged, I pulled the fuel line off the filtor(going to the carb), stuck the line into a mixture of half gas half carb cleaner, I fanned it up and in 2 or 3 minutes it started running well, hope this helps.
