Stalling spree

[banshman]

but this thing only has 240 miles on it and its never been molested? what should I do?

[Bear45-70]

It is a 1986 piece of equipment with only 240 miles on it, which means it sat a long, long time. Sitting is bad, unless someone with the know how, pickled the engine for storage. It almost never happens, I have only ever had 2 engines that were stored properly and were a snap to get running again. It is never easy to revive something like this and it will take patience and trial and error until you find what is wrong.

I actually changed the gas and cleaned the carb and it started right up.What I mean is How would the float adjustment get screwed up?Does that needle have clip adjustments on it?I dont remember.

Negative. I doubt your problem is in the float. Your symptoms describe that tiny hole you have already discovered. It will start, but lacks oomph and bogs. It sometimes stalls on decelaration. When you blew air through the passage, you did more harm than good. IF there is any varnish in that hole, instead of the compressed air pushing it on out, it will ball it up and make the plug worse. Carb cleaner is best way to clean and test. BTW, be careful with these cleaners as some are very strong and burns like lighter fluid. Not good for the eyes are even skin for that matter. Gunk brand seems to be the most unfriendly to the skin.

The interesting thing about that hole, it is the smaller, primary, jet. But it seems to impact secondary performance (acceleration) more than idle.

i'll let you know how it works.

Please explain how you came to your conclusion.

"I doubt your problem is in the float."

Since the engine starts and idles fine, both hot and cold, then the hole is not an issue. The engine dies after running down the road then stopping for a traffic light or sign. How on earth can the engine idle fine except when he brings the machine to a stop and have the itty bitty little hole be the issue since that hole is the IDLE CIRCUIT?

Please explain how you came to your conclusion.

Elementary my dear Watson. I've had those same issues in combination and solved it by cleaning the hole, not once, but twice. The motor will idle from the main jet but bog on throttle.

What is elementary is that the itty bitty little hole is the idle circuit's fuel supply and without that fuel the engine WILL NOT idle, ever. So your theory has , excuse the expression, a major hole in it. Engines can not idle on the main fuel circuit because there is not enough air flow thru the carb's venturi (AKA vacuum) to initiate the fuel flow thru the main fuel circuit, that is why there is an idle circuit to begin with. Idle circuit's outlet is always behind the throttle valve or slide so at idle it has a high vacuum to draw the fuel thru the idle circuit. This is basic carb theory.

This is basic carb theory.

I don't know so much about that. What it is, is what it is. I know what my problems were, and I know that a Hondasan with 20 years experience told me how to fix it. I cleaned the small passage and it solved my problem. You can't argue with success. I understand theory, but sometimes theory needs to be reexamined to make sure it's right. That passage may have a different purpose.

Yeah, but physics doesn't change and this is physics at work.

According to physics, it is impossible for the bumble bee to fly... But somebody forgot to tell the bumble bee.

I have never heard a physicist say that about a Bumble Bee. I also know that a C-124, a big old piston cargo plane with B-29 wings and engines supposedly won't flew either. But the morons that claimed it wouldn't fly, did not remember to include the lift created by the fuselage. But even if the Bumble Bee thing is true still doesn't mean your theory doesn't suck worse that a carb at idle.

[devenex]

Bumblebee flight is very explainable, so long as you don't use linear approximations (i.e. try to solve the physical systems on a napkin):

[portets]

wow guys, haha

this is totally off subject from the carb argument.

i think you both won. or both lost.........

[banshman]

I have created a monster.Why dont I try to clean that hole and Ill let everyone know.I have tommorow off and thats first on my list.
Thanks to everyone for the input.
