You'll have to wait till next week for that test drive Kev.
Chris came over today, while I was still at work, & moved the accelerator pump cam to the second position. When I got there we took it for a quick blat up the lane & through the local village. It definitely accelerated slightly better, but is now spitting, backfiring & generally driving like a bag of poo. Odd cos it wasn't doing that when I took it to the diner a couple of days ago. Feels like a fuel problem, or maybe an air leak, (at the carb, rather than the exhaust). There's fuel in the filter, just before the carb & it looked reasonably clean. There's a second filter between the tank & fuel pump.
He took the fuel metering block off. The various jets & passages appear clear & the power valve's working, but there was a layer of yellowy, chalky gunge on the inside faces -possibly gum residue from old fuel? We used 2 different brands of tank sealant in the fuel tank, so it's possible it's dissolved & found it's way into the carb, but hopefully not. Loony dunked the metering block in his sonic cleaning tank with a splash of thinners, which seemed to work.
Anyway, Chris ended up taking the carb off & has taken it back to his workshop to strip & properly clean.
While he's doing that I'll pull the exhaust headers off & reseal them against the heads with some Gun Gum to stop any air leaks there, as well as putting a smear of blue sealant under the carb spacer block that sits on the inlet manifold.
Lots of bodywork jobs to do over the next week, as well as drilling out & rebolting the caliper/mudguard mounts using larger, shouldered bolts. So plenty to be getting on with.
You know you're more than welcome any time though Kev.
Nice to see Old Newbie too by the way, though I didn't get to chat to you much mate. Hang in there with the trike paperwork -it'll all fall in to place soon!
