Re: PA50 CARB

Re: PA50 CARB

Give us the dope.

Does it run?

Does it run but not idle?

Does it idle but not run fast?

did you assemble the fuel bowl in the correct direction? it fits on two ways but only one is correct. cleaning is simple. tear it apart, run wire thru every hole in the carb body and all its parts, follow up with blasts of carb cleaner, reassemble.

Re: PA50 CARB

heres the dope, as one of yous adequectly put it, the ped will run beautifully from half throttle to full throttle but below half it runs horribly and dies. the fuel bowl is on right it (thye carb) been cleaned three times and looks like new, all the holes are very clear in everything that we can see and we've blasted stuff through it. we dont know if a small brass gas/air mixing tube is in right and we dont know what it should look like so if u have any clues/ suggestions as to how it sholud go tell me it all

thanx

if the bowl is installed backwards, the float binds. this can explain your idle issue if the engine is flooding. you should also look for an air leak at the intake manifold, cylinder base gasket, and crank seals. www.partsfish.com should have an exploded view of your carb.

Re: PA50 CARB

The little mixing tube (emulsion tube) goes in only one way.. One end of the tube opens up to a bigger hole.. this end of the tube is also slightly smaller in diameter.. this end goes upwards. (The other, bottom end has the cross-drilled hole near the end of the tube.)

Once the tube is seated up in the emulsion chamber, it's tip extends slightly into and can be seen in the carb's throat. The main jet seats it and holds the tube up in there.

Since you've got low speed trouble, something related to low speed running may be clogged.

There is an idle jet pressed into the carb body. It is under the flat-headed cover screw (below the idle speed screw). This jet's bore hole is very tiny. Find the thinnest strand of straight wire you can.. and poke it into the jet's bore to assure it's open. A single strand of throttle cable may be small enough. The bore hole is so small and deep in there that you may have trouble seeing it or getting the wire into it.

Although this jet is an "idle" jet, it does contribute fuel to part throttle operation untill about half throtle.. it and the whole idle pathway must be clean and clear.
