Engine runs on choke but dies without?Special tool to adjust hi /lo carb settings?

Your main jet in carburetor is fouled and needs to be cleaned out. The choke circuit bypasses it but when you remove the choke the gas is supposed to go into engine via the main. If clogged, the engine will quit for lack of fuel.

Either clean the carb and jet or replace carb. And yes, newer carbs have basically non a adjustable jets which is ridiculous since each engine is unique and has to be properly matched to new carb. Way around this is by either buying the special tool (he-- with them) or using a dremel tool to cut into head of adjuster a slot so that you can use a regular flat blade screw driver to adjust.

The car get power and frequently goes off


what engine? size displacement and cylinder count.
is it carb , EFI TBI or MPI injected.
carb, or 1 injector or 4 injectors,
most cars this year have all 3 choices. in USA< last year for carbs here.
if carb, then , maybe the carb is dirty , as they all do and frequently.
we clean them and kit them. and adjust them.
This is a USA form and we dont have cars made for Botswana here.
so answer will be few, lacking ,engine size, or VIN number to see engine option there.
or a photo of the engine,will do wonders, but seems to never happen.

850 double pumper has of idle stumble when going down road

The good thing about a Holley carb is they can be custom built to just about any engine.
The bad thing about Holley carbs is you can work on it for months trying to get everything adjusted right.
You'll have to figure out if it is a lack of fuel or too much air coming in.
The accelerator pump travel can be adjusted up or down as well as the power valve.

I have a 2005 honda 150f it seems to be lacking power pretty sure its a carburetor problem does anyone know what kinda problems 150F have and how to fix it

your right it can be carburator( dirty or adjusting ) but usally when its carb it will bogg and miss a little( with no consistancy) could also be valves need adjusting,valves should be checked every 6 months for proper clerance ( 0.003-0.004 on filler gage.) signs of valves needing adjusting are slight popping thru exhaust when letting off throtle.and decrease in performance..... also check your air filter( might be restricting air to carb.) always start with the easy and cheep things and work your way up!!!!

My kmx is losing power it's like hesitating especially uphill and .lack of throttle play

So adjust for some throttle play at the adjuster nut at the top of the carb.. Remove and clean the carb. Move the clip on the jet needle down one notch. This should take care of the problem.
Best wishes.

1983 Mazda RX7 lacks power rough or no idle

Sounds like carb idle air or fuel jets are clogged.. Test pressure with a gauge to be sure. Float level and drop needs to be exact.. Operation of the whole carb relies on this. Probably why you are not getting any change in your air/fuel adjustments.
