Re: Mystery non-start issue. Help needed!

Hi all, Apols for delay - life has got in the way, as it tends to. Had a chance to get the carb mostly apart this afternoon to check if it was gummed solid, and although the fuel does seem a bit yellow, there's no sediment in the float bowl, the float moves fine and actuates the needle, which itself...

Re: Mystery non-start issue. Help needed!

Definitely confirmed fuel pump running fine as directed the input to carb into half a Coke bottle which it filled at a good rate. Fuel looks a little yellow but certainly seems petrol-like. Having taken air filter off, carb piston does seem to have a bit of a buildup of black gunk on the side, I've ...

Re: Mystery non-start issue. Help needed!

Carb is indeed non-standard. A few years back a mechanic friend of mine swapped on a 1275 head and this 1.5'' (HS4?) SU for a bit more poke. Have never had to fiddle with it at all and always ran fine. Silver braided hose is fuel inlet into carb. I've removed it to check fuel trickles through, but w...

Update: Had a chance today to have a tinker. Followed advice and did the following: Plugs out, rocker cover off, dizzy cap off Rotated engine on starting handle until could visibly see piston rising in no.1 spark plug hole.

Re: Mystery non-start issue. Help needed!

Appreciate the responses, thanks. @Bill - still running points & condenser. In fact just to rule them out I changed them over for a new set from a service kit just in case one had been fried/otherwise by the alternator messup. @Stephen - I wondered the same. Hence checking where cyl 1 TDC was, t...

Re: Mystery non-start issue. Help needed!

Good thought, but sadly I had already checked the fuel getting to the carb, and it's not stale, no sediment. Just to make sure I popped a couple of quids worth in a jerry can at the local garage and chucked that in the tank, too.

Mystery non-start issue. Help needed!

Hi all, Looking for a bit of help from the Morris Minor hivemind.. Have had a '68 Minor 1000 2dr for the last 12 years or so. Bought as a bit of a passion project, and enjoyed many years of driving it all over the country, giving it small tweaks and upgrades etc. Sadly due to changes in circumstance...
