Help!!! Engine Won't idle!

[Martin L]

Re built engine over Christmas. Have done around 300 miles trouble free driving so far. Got it out yesterday, will not tickover! Any ideas where to start first.....going to Ninove Friday! Hopefully.

Has it been sat a while? I had the same problem, ran it a few miles and it was fine.

No.
Since putting engine back in after rebuild have been driving it twice a week, getting a few miles on it before heading to Belgium. Has been absolutely fine on every drive. Not touched /messed with anything and yesterday morning once off choke will not tickover!
Worst timing..... my B'day this weekend and have lots of plans to see family and friends so haven't got much time this weekend with plans in place.

As Davidoft said what carb are you running and give as much info as possible in the setup

What carb are you running?

Solex 30 PICT 2
Flamethrower Coil
Electronic points
Standard HT leads

I'm leaning towards fuel problem, maybe blocked jet!

I would get a service kit if you can from eurocarb. Give all the jets a good soak in a brake cleaner. I know you have limited time.

Id look at the idle bypass circuit on the carb. In the engine bay it faces your main battery, and runs in an extrusion on the side of the carb. It runs from the small diaphragm pump horizontally , then kicks upward at right angle. There is a small jet at the top, take it out and clean only with carb cleaner. This kept blocking on mine and I had to take the carb off and clean the whole passageway, back to the diaphragm pump. There’s a small pin partway along. If you pull it out and carefully turn the carb upside down you will find a small all bearing drop out. If you’re lucky you won’t need a carb rebuild kit.

Crisis averted. Took idle jet out and cleaned......running fine now. Just being a Mary and panicking!!! Really looking forward to Ninove next weekend and would have been more than gutted to have missed it.
Thanks for advice everyone.

Have a nice safe journey. Hopefully I can be there for next year.
