Twin Weber Carb Issues
Posted: 31 Oct 2018, 09:11
Morning all,
I've been having a few carb related issues lately, (see this previous post http://forum.club8090.co.uk/viewtopic.php?f=37&t=165925" onclick="window.open(this.href);return false;), with the van being very hard to start when hot and then flooding and it's been getting steadily worse, it now happens on short trips as well. Cold start is fine. It was initially thought that maybe the fuel was getting hot whilst sitting in the carb. Whilst having clutch slave cylinder replaced I got my local specialist to have a look at the carbs, which are only 3 years old (Spanish one's not Chinese), and their opinion was that the float may be sticking, so the chamber is filling up whilst it's stopped and stationary (eg putting petrol in) and the throttle spindle is also warn. I spoke to Gower and Lee, who I bought the carbs from and apparently, spindle wear is quite common due to the pressure of the throttle linkage. So it seems I have 2 options, a rebuild kit, which apparently doesn't include a throttle spindle (assume this is the throttle shaft on the ICT34 diag), or get another couple of new carbs. The cost of both options will be similar, as the labour to do the rebuild will come out similar to the cost of getting new ones and having them set up.
It's very annoyng that these new carbs have only lasted 3 years (less if you include the period I've been having problems!). Has anyone else suffered similarly with new webers? Any advice opinions will be much appreciated. I will be asking the mech to try and make sure the throttle linkage is set properly to ease the pressure as much as possible this time as well. I live in Hastings, so also if anyone knows a local carb specialist that would be great.
Cheers,
Peter
