I cant see any pics ?

Mark, whats the story with your website?

Why ? dont you like it ?

Hi All

I have had a few enquiries regarding engines leaning out after a jump, this will be beneficial to racers and bashers alike. What you find is when you gas it off a jump the idle rips up bringing the nose up, then you compensate with brake to tip it back .. sometimes this dosent always work out.. Especially those with sensative brakes. Most people will notice this happen suddenly after a few litres of run time and go everywhere looking for the leak ... Everywhere but the CARB BOOT ! ( dramatic orchestral stab ) OOOH ! pennies dropping ?

What happens is the carb boot is probably not made of a quality nitrol base and will soften and expand , this can happen on any engine as it is expensive to make one from nitrol .. about 11 cents more per unit !

SO ! what you need to do is seal the carb boot with a small thin cable tie where it reaches the carb stopping any air getting in ... You can put a dab of silicone around the base before the cable tie if you like , this should eliminate the problem , if it dosent then check it closely for tears and replace.

NOW ! why does it cause this problem ?

What happens is when you jump you are essentially clearing all excess fuel out of the engine , leaving not much in there, when you are in the air and the throttle is at neutral its closing the carb. The residual suction of an empty engine scavenges for fuel, if the boot is loose the air will be re directed through the side and by pass the inlet . that suction is wasted and creates a lean engine till you blip it again.

Now there are other problems that can cause these symptoms so make sure if you have it to check everything .

Hope this helps !

so massive, you recon seal up the carb boot with a bit of glue maybe? i was thinking of doing this to my engine

Glue, ya enviromental bandit Tom. lol
I thought you Greens would be using tree bark chewed by 30 virginal Nymphs of the forest (security provided by a Yowi), after a little ceremony to thank the tree gods for aiding in the enhancement of your aura and lifting of your inner being, you know, to protect the overall karma of the whole ritual.

DuDe ! im trying to type from the floor LMAO !!! Chewed bark ! lol A Yowie lol

Simon you have missed your calling lol

No , glue is as far as i know heat sensitive and it may crack from vibration .. the other thing Kev Lewis suggested is an O Ring .. which is a great idea !

Neil's the name, Markov. I'm the good looking fella with anorexia from Newy. (didn't think I was that forgettable, go'n ta slash me wrists) lol

Has the O Ring you suggest bin vibration tested on the Massive Mods vibration tester (if you don't have one, get the one that Larry is using to satisfy the girl in the photo, lol)

Hey Tomo,
heard you prepared an environmentally friendly viagra for him, made by the druids out of hemeroids, goat gism and ginseng? lol

lol WTF??!!

ay Neil, Mark said he was after some "O ring" action, he said the O ring keeps it tight... WTF!!?? he said he will be going to Bali, or as the locals call it, "Barri"to hook up with one of Lazza's GF's friends

man dead set, i leave for 5 minutes and it becomes Jibber city here!

Ah Neil ! thats right i always got you two guys confused, you look so similar lol

And Tom what do you mean beginning to be a gibber city , this is GIBBER CENTRAL !
