Cold starting - Tiger 650

I have been trying to replace / repair some old parts this winter on my 1969 Tiger 650 to be ready for spring

Replaced the points with an EI system - great now !
Replaced the old Amal carb with a new one (slide was worn out) and am having the old one rebuilt for a spare.

Tried to start yesterday (temp around 48 F) and it was very hard to start. I ended up squirting some carb cleaner into the intake to get it going and it ran great after that. Any ideas why it would be so hard to start or is this just a classic cold starting issue

Seemed like maybe just not getting fuel up to the carb. Maybe jets are too small? Vacuum leak? Runs fine after it's warmed up and has no issues.


Thanks,


Jeff

Classic cold starting.

You need to tickle the carb till it starts to dribble out, then activate the enricher lever (turn it to SLACK OFF the cable, not pull it up tight)

Should fire right up w/o starting spray.

I would add that with electronic ignition,it may not start if your kick is not fast enough.A lot down to experience and usually no choke needed.If all else fails,easy start is your best friend.

It kicks easy once I hit it with some carb cleaner spray in the carb on first kick.

I am wondering if I tuned it with the choke on and now it's too lean when I start it cold.

If you did, it might be.

Start it again with Pauls instructions.If not first kick,it should start by the third attempt.Tiny bit of throttle applied as you kick it over and when it fires,a little bit more.Not a great big handful.

Thanks too all !

I will double check the choke and make sure it's slack on starting and I didn't tune it with in "ON".

Seems like it just needs more fuel on the cold start and once I shoot some carb cleaner in there it gets the vacuum going and fuel is sucked in?

It's a new carb and was running fine until this start after the last tune in the summer. Maybe some fuel got gummed up in the idle or pilot line?

I have a 1971 Tiger 650. Cold starting procedure is..... clear the clutch, decent tickle, kick over three times with ignition off, tickle again, ignition on and away it goes !! Have done this on many an occasion on weekends away with the Club at country pubs at 10 degrees C or less.
good luck....

Pauhig has hit on something............close the choke, tickle the carb, and with the key off, pull in the clutch and kick it over until it kicks with no resistance; this has the double benefit of freeing up the clutch and drawing fuel into the motor, then re-tickle the carb, turn on the key and kick it over with just, what the Brits would call, a "whiff of throttle". It should start with no problem.
