Title: Is throttle-starting (non-choke) bad for the engine?
Post by: Darkstar on April 26, 2016, 03:08:04 PM
I dismantled and cleaned my carbs over the winter, but failed to clean the choke circuit. So it won't start with the choke, but it will if I open the throttle wide for the first second, and then hold it at 3000rpm for the remainder of warmup. Doing this races it to about 7000rpms but only for a short moment...but the oil is still thick. Is this bad for the engine in any way?  I'd rather chew glass than tear the carbs apart again right now...

7000RPM can't be good on a cold engine;I'm reluctant to choke my cold bike past 2500RPM.....if it was me I'd make the glass choice.

Me too.

If these engines didn't need a choke...then they would have not designed them with a choke....

Fix it right...then you cry only once....otherwise you  cry every time you try to start!

Actually, I just checked and it's 4000rpm, but I suppose you're right. I should take the damn thing apart again. ugh

Just an idea, starting at WOT leanss out the mixture at starting. Maybe you are way too rich which is why the choke does seem to work. What colour are your plugs?

I live in Florida so its never really "cold" my choke revs my bike up to 4000 every time and I only need my choke for literally 30 seconds then I can let mine idle without stalling. I also get the distinct feeling this isnt quite normal.

I've tired using the throttle to warm it up  and it just stalled my bike.

The Wadsworth Constant strikes again... Very cool video nevertheless. Videos like this really make you stop and appreciate just what amazing pieces of technology, knowledge, and engineering engines are. They are fascinating pieces of machinery!

Update: there's nothing wrong with the carbs, I had the idle set too high, so it was too rich. Backed it off and now everything is AOK. Thanks guys
