Walbro carburetor settings

Recommended Posts

Hi mark, do i make those turns on the H and L from the position they are in. I've not touched anything from purchase so assumed it would be tuned already from manufacturer. Now it won't run on idle, keeps cutting out. I did the first four heat 15 min heat periods on idle then ran it for 15 mins on quarter power but since bringing it home it won't stay running on idle even though I've not adjusted anything. Nightmare. Can you help? Explain in detail what I've got to do on carb to tune it. Soz for my questions etc.

The settings I give a factory settings there is no perfect settings I can give as there are so many variations but they won't be far from factory, to keep it running turn the idle screw in.ย 

It would also be a good idea for you to grab another spark plug as they can get fouled whilst running in๐Ÿ‘๐Ÿป

Btw the plug is a Ngk CMR7H

Hi mark, i cannot get the car started and its really annoying me.ย  Ive replaced the sparkplug with an NGK CMR7H,ย  it's sparking but it just won't fire up.ย  Should i buy a new lead that goes from coil to sparkplug and if so where do i get one from?ย 

ย 

Many thanksย

When i took the plug cap off for the first time the copper spring part that sits on the sparkplug came out of the cap itself. I stuck the spike back in the hole on the cable and fed it back into the cap and according to tutorial i watched I've fixed it. The cap goes on the sparkplug just fine now.ย  It still wont start......HELP ๐Ÿ™‚
