1962 A10 GF Kick Back on trying to start up

[CheeserBeezer]

To eliminate mixture issues, have you tried using the choke when hot?

OK, at the weekend I checked the ATD and now that she's lubricated, she looks to be working, she retards when kicking her over. Check points gap and timing and reset it again, closed her up and she started first kick on full choke. Didn't run smooth on choke, but when warm ticked over nicely and picked up well. Left her for 30 mins and started, but not well. So I'm thinking it must be fuel starvation, so that's my next investigation

Worth checking the taps and carb are not blocked.  I cleaned and cleaned my tank but still after a few runs one tap was blocked solid and so was the carb gauze.  Remind me, which carb?

Hi Terry,
Starting and stopping in the garage will lead to more difficulties due to the plugs getting fouled and not hot enough to burn themselves clean. It is a consequence of the crap petrol that is on the market now

drained the yonda carbs the other day and within a couple of minutes it was milky with moisture , it is horrible stuff

Its is, the only way I can get my chainsaw to run is to drain the fuel after every use, never used to have to do that.

No such problems using E5 with a splash of 2 stroke oil. The chainsaw can be left for months and starts with a couple of pulls. Same with the 4 stroke lawn mower which is left all wet season.
With the bikes I run them with the petrol turned off leaving the carb dry.
Good starting followed by poor starting could be a cry for help from the mag.

Yes, even though the symptom isn't what we'd normally associate with a poor mag, it is such an easy swap it's worth doing to eliminate it. I'm happy to lend a mag if that helps.

Thanks CheeserBeezer, but the Mag was Recon in 2021 by API Magnetos Ltd and the previous owner never put it in the bike. I've installed it and it appears to work fine a good spark on both cylinders. I'm now moving the bike out of the Workshop this weekend and hopefully take her out on the road, so we'll see

How old is the petrol you are using?  I had a bike severe spitting back and it was cured with new petrol.

dont know what ethanol content you have we are on E10 here in Canada I never leave it in anything over winter always drain carbs and tank ....ethanol has a short shelf life and attracts moisture best thing ever invented for small engine shops .
