Difficulty restarting after journey...

[bigbulli]

I'm having difficulty restarting after journeys. It appears the choke /engine is flooding. My mate held open the accelerator lever to get more air in and it started ok. What do I need to do to fix it? Didint have this problem till I rebuilt fuel pump and cleaned carb, would turning the auto choke make a difference?

how long between when you shut it off and when you try and start it again?

Check your fuel pressure. I've had the same problems.

It seems that as long as you motor is warmed up good and it isnt super cold than for that short of a time period your choke shouldn't be kicking back on. If it is that might be the problem. You could also be dealing with a vapor lock issue, strange as it might sound. My old '58 would vapor lock if I let it sit after driving it but opening up the carb would get it flowing again.

Check the adjustment of the choke valve.

sounds like the float level is too high, and it is draining the gas down the carb. that will make it hard to start between 5 and 30 minutes after it has run, but it will start right up after it turns off, or if it has had long enough for the fuel to dissipate.

Check the crankcase oil to see if it has the odor of gasoline.
Maybe the float has a crack in it.

Or you can add a washer underneath the needle valve...

or the gas cap is not vented.......rebuilt carb,set float level,new fuel pump and used pressure guage to set fuel pressure..still had hard start after running just like you..........got a vented cap and it all went away...............phil

[bigbulli]

What height should the float be at and where do you measure it?

Cheers

Someone will point it out if I am wrong but I've rebuilt VW carburetors (30 PICT-1 to 34 PICT-3) and they have all had plastic floats, so there was no way to bend them and adjust them, and no mention of it in the directions with the rebuild kit or in my motor manual. The 28 PICT carburetor has a different float so I don't know about it.
The float needle valve that is in the rebuild kit comes with a washer (the washer moves the float needle valve down, a little, so the float won't be able to float up as high) but I can't remember in what cases it is to be used.
To check the float needle valve for any leaks, remove the top body from the carburetor, press up lightly on the needle in the needle valve, and blow air into the fuel inlet. If air comes out of the needle valve, replace it.
To check the float for a leak, push it down in some hot water; if there are any air bubbles, replace the float.

OK, so I bent the float up, replaced the needle valve with a solex one and pre loaded the fuel pump. Again started and drove really well, once stopped and left for 15 mins wouldn't start. I took the fuel pipe off from the fuel pump and turned the engine over by hand, no fuel, I then got father-in-law to turn the engine over by the key and after more than a few turns petrol came thru. I left it 15 mins and it started again. Not convinced it fixed so I will try again tomorrow to see if I can get it not to start, if that make sense....any idea's?

as someone else stated. next time it happens take off the gas cap and listen to see if you can hear a swoosh or sucking sound as you take the gas cap off. your gas tank might not be venting

or drive the bus around with the gas cap off and see if this still happens. dangerous to a point but you might find out you need a different gas cap

The carb in the '56 westy sometimes has the choke butterfly stick.
It happened worse after I cleaned out the carb.
The moving bits need to be oiled from time to time. That helped. But sometimes it still sticks.
When it doesn't start, I have to go open the engine lid, manually move the arm that turns the choke butterfly so it is free again. Kinda annoying.

I intend to put a manual choke 30 pict carb on it, so have just been dealing with it so far.

Maybe this helps (?)
