Straight spark plug head

[WINDY CITY BOB]

I've read your plug (or o should say I looked at it) I sometimes have trouble understanding things on paper. I have swapped out carbs completely still have problem.

Ill get to the bottom of it

Its a air leak in the carby intake. I've already made a gasket I willl put it on tomorrow. Made out of metal tape layered upon layers.

its either an E thread length (19mm) or its a P tip(projected).

the cj8 is actually slightly better than the b5Hs as the thread is marginally shorter, about one thread less...

yep, unfortunately that damn nipple doesn't unscrew like an NGK does. doesn't work with my plug boot

ive got an elderly cj7 that does unscrew...yerp, dont think i have seen any small engine plug that unscrews in ages. approved for aircraft use

swap the boot for one off the brushcutter, they have that funky spring inside...no brass bits to vibrate apart! no threads at all...

or use the entire lead and boot off a car.

*has mental image of someone sticking rear panels of car on bike...it doesnt fit!*

trunk? we call em the boot no idea why...boot. where the f did the name boot come from?
