The Scrambler Won't Start

[PaulBIskup]

Thanks to everyone in this group for all of the useful information you've posted that I've used in the past. Now unfortunately I have to post a question as my 1967 305 scrambler won't start. The other day I was starting my bike for the first time in maybe 8 months. The engine started and revved like crazy as the left carb valve had stuck open. As it was running and before I figured out what was happening, I regulated the rpm by moving the choke up and down so it would sputter then rev, up and down. I didn't run it for long like this and sputtered it out. After it stopped a bit of oil ran out and onto the shop floor. I've cleaned the carbs and they are moving great. I've cranked it and it almost starts sometimes but it will not start now. Does anyone have any ideas on what may have happened that would make it not want to start at all now? Thanks everyone.

Clean the carbs, especially the pilot jets, clean and adjust point and timing, replace spark plugs.

I would check the timing, especially if it backfired during the 'reving up'. Sometimes that can cause the advance to stick on.

Cheers,

Thanks for the pointers. I was wondering if the timing could get knocked out of whack, and it did do one minor backfire. I'll check it out and see if that's the case. Any tips on timing the thing? All I have is a Clymer Vintage Japanese Street Bikes guide to go with. Thanks.

couldn't hurt to check the valve clearances while you're at it...from my own experience...

Paul,
To do it correctly and eliminate any chance of having problems follow Ed Moores (Loud Mouse) tune up instructions. You will find them on the left side of this page in the yellow column under FAQ. Follow exactly as written and you should have your CL running again as long as the cam chain and the other mechanical items are properly installed. Cliff
