Just put new engine in and although it starts up I am looking for some help with the settings and tuning it.

For instance, do I start with all the screws all the way in and then back out so many turns?

Is the choke on when starting and then off when warmed up? Off as soon as it starts?

Thanks,

Mark

It should start up and simply run seeings you didnt do any modifications.....

Take the airfilter off and look at the choke flap...flap in front of hole means chokes closed..No choke flap in hole means choke is open/

On my bikes its "up" to set choke and down to turn it "off"...

On that engine you pictured its opposite.....ON/OFF is imprinted on the airfilter by the choke knob ..

To Start the engine...:Its just like a weedwacker/backpack blower..

Youre supposed to pump the primer bulb 5-8X

Set choke

Pull pullrope til engine starts then turn choke off 5-10 seconds after the engine starts

or

If the engine gives a strong reaction stutter but wont start like its too rich turn choke off and pull a couple more times and it should start-up..

After it starts up if needed set the idle screw...

Good Luck

Right now it seems like I need to set choke about half way to get it started and then have to move choke up or down to keep it running. Still do not have it set so that it idles correctly, especially without moving choke up or down.

Seems to me like youre having similar problems as the old engine..

How did you make your first mix for first start-up?

What octane fuel did you use?

Was the fuel fresh and recently bought?

Pull the sparkplug and see what it looks like...Those Torch and Chinese brand sparkplugs aren't very good and its recommended you swap it out for a quality sparkplug like NGK...

As a goof grab the old engine set the choke and start it up on a bench with just the fuel in the carb....It may surprise you by running ………..

Most times what seems tuning related could sometimes become electrically related..

I have a feeling this is one of them times...Good Luck
