STARTS FINE NO PROBLEMS..GO UP THE ROAD , WITH A LOAD ON ENGINE , STARTS SPITTING & FARTING LIKE ITS NOT GETTING GAS..I PULL THE CHOKE OUT 1/4 AND IT RUNS LIKE A TOP..!!!!!

I DID NOT HAVE THIS CARB REBUILT OR EXCHANGE IT WITH JOHN AT MIDWEST ...I LEFT IT ALONE WHILE I DID THIS RESTORATION AS IT RAN FINE ..NOS FUEL VAC PUMP , RELINED ORIGINAL TANK , ALL NEW VENT AND FUEL LINES..!!!

TIME TO EDUCATE ME ON IT..???? WHAT DO I NEED TO DO ??

hillbilly, Is the tank vent clear of obstruction? also, have you checked for good fuel flow before the carb?
they're have been reports of some re-lining their gas tank that seem to fail and accumulate debris in the carb.

Vent is clear as pick-up is NOS..I blew with air hose in & out of it..

Flow is solid pipe , pulled fuel/vac looked for any signs of debris -NOTHING

I also thought the new reline would have something to do with it but it is still in tact..

I removed line to carb ..turned it over sprayed gas into cheese cloth clean as a bell !!

Will it run smoothly at 50 MPH when on level ground and not accelerating?

the need for choke is your getting to much air......vacuum leak ? have you checked around the base of the carb. also, make sure all the fuel line connections are tight.

I had the same problem and realized I forgot to tighten a clamp on a hose connection before the (Elect) fuel pump....,

6 hours of scratching and all I needed was a screwdriver.

For it turned out to be the simplest and obvious .

RUNS LIKE A TOP WITHOUT GIVING IT GAS ..I HONESTLY HAVENT PUSHED IT TO 50 MPH YET WES K.... STILL TAKING IT EASY ON A BREAK IN 35-40 HAS BEEN IT...


GOOD POINT MODIFIED WILL CHECK THIS OUT..I AM SURE I DONT HAVE A FITTING LEAKING AS IT WOULD DRIP..WILL CHECK CARB AND GASKET IN THE AM..

Are you running stock military ignition?

YES SIR ....

Take a look at your diaphragms for the metering rod and the accelerator pump.

Check the centrifugal advance in the distributor.

Check each spark plug lead for leakage (shorts to ground)

Here is what I found ....


Carb nuts where loose ???

Also the valve for the PCV valve was closed ,, dont know if that has anything to do with it...

Will have to wait until early am to go for test ride....

sheriff dept. doesnt move around here until 9 am..

She will run poorly after awhile when the fording valves are closed.

RUNS LIKE A CHAMP NOW !!!!!!!!!!!!!!!!


THANKS GUYS FOR THE INPUT..........
