Quick update
Started bike several times today.  Revel up to about 4000 once when running but had it idling several times.  Vast improvement from what it was doing.  ďRepairing ď the o-rings fixed part of the problem, so we are on the  right track. Next will be to remove carb, check manifold for leaks, and maybe replace the carb with another one.
Thanks again for your help and patience with me,

Bonus,  progress.

If, like me, your hearing is not the best,  another pair of ears might help you locate the area of the leak.

Found the leak.
Finally got back to working on the trike. Pulled the intake manifold off and sure enough one of the manifold connectors was broken ( not sure of the proper name of the rubber piece between intake and head ). Ordered one on eBay, should be here by Tuesday, back together and progress will be made.

Thanks for all the ideas and assistance,

Re-assemble everything, put the Weber 32/36 back on it, a little shot of spray start, fired up and sat there and idled beautifully.  Almost ready to ride. What a relief.

Thank you one and all for your ideas and assistance.

Ride on............

Good one.

I know it's a tall order,  but it would be good to see a video when you get to ride it.

For a Neanderthal like me, that might be a tall order. These modern devices are still new to me. Iíll just have my grandson film me and the trike.
Had the back wheels off ( on jack stands ) and ran it through the gears . Shifted good, accelerated great, but I donít have rear brakes yet so I donít know how it will stop yet. Waiting for a master cylinder to arrive from Summit. Then I can give it a real try.

Ride on............
