Hi all,
I have a 1600 twin port in my 71 early bay, running a 34 PICT 3.
It's a newish 'chinese quality' unit but it was easy to set up and seemed to be ok.
Only done 1000 miles in it as I don't do a lot of mileage.
I think the carb is ok.
We're based in London and on the way to the Latitude festival in Suffolk this year we broke down.
We were running fine and then we started bunny hopping.
I pulled over and the van stalled.
I got it restarted but it was coughing and spluttering with not much throttle response.
Then it cleared and we drove another 5 miles with it intermittently coughing and stalling, then restarting, clearing and driving fine.
My initial thoughts was dirt in the carb.
I called the AA anyway and they got us running by clamping the fuel supply, 'sucking the dirt through the carb' and then setting off- but with the choke full on (held by a cable tie). Got us to the campsite, 45 minutes and probably 30 miles away. That was Thursday.
On Saturday, i started the van , it ran fine for a few seconds, then spluttered and died.
I took the carb off, took the float chamber cover off, cleaned the chamber out (think there was black stuff in there), blew the jet in there through and put it all back together.
Started first time all fine.
On the Sunday at Midnight (going into Monday) it started fine and we drove home- 3 hours and a hundred and fifty ish miles in the dark. Didn't miss a beat, which I was thankful for!
Monday AM, I used the van to drop the kids locally to school- on second drop off, about a mile into the journey, ten minutes after start up, same issue, rough running, spluttering, died.
Took the carb off, couldn't see dirt, blew the jet through, put it all back on.....same issue! Spluttering, stalling.
Tried it a few times, eventually it worked and i drove home, no issues.
I bought an unknown condition second hand Bocar carb. Cleaned it, put new main gasket on it and put it on the van.
Same issue. Exactly.
I'm not sure where to start.
I'm not totally convinced it's dirt though- filter looks clean.
Can a fuel pump run intermittently?
Or the coil?
Points?
Any ideas on my next steps ?
Any help appreciated.
Thanks
Kevin
