dieseling can be caused:
1. Built-up carbon in the ignition chamber can glow red after the engine is off, providing a mechanism for sparking unburnt fuel. Such a thing can happen when the engine runs very rich, depositing unspent fuel and particles on the pistons and valves. Similarly, non-smooth metal regions within the piston chamber can cause this same problem, since they can glow red. It has also been suggested that an improperly rated sparkplug can retain heat and cause the same problem.

2. A carburetor that does not close entirely can contribute to running once the engine is off, since the extra fuel and oxygen mixture can combust easily in the warm piston chamber. Similarly, hot vaporized oil gases from the engine crankcase can provide ample fuel for dieseling.

3. Incorrect timing.

4. An engine that runs too hot or too lean may produce an environment conducive to allowing unspent fuel to combust.

5. An idle speed that is too fast can leave the engine with too much angular momentum upon shutdown, raising the chances that the engine can turnover and combust more fuel and lock itself into a cycle of continuous running.

I am going to say something is wrong with carburator or your timing is way advanced.
check the timing first. after that move on to the carburator and make sure it idles around 800-90. make sure the gas pedal cable isn't too tight. loosen it up and check for idle. make sure the throttle plates close up. check and recheck everything.

be nice.

it is fixed.

woot...anyways.....i dont think a header would solve his problem....that is more of a mechanical problem then geting the head to flow better.

well, weber supposed to be bolt on upgrade, but it is not like that. you still have to make sure it is working right and tunned properly.

EGR valve would have nothing to do with dieseling. all it does is actually sends exhaust back into intake. it should reduce dieseling.

My Weber did it too. The mixture was off. I pulled the screw out a half turn and it took care of it.

Kinda funny that you tell someone to learn how to spell, then you leave out all correct punctuation and correct capitalization.

hey man...as long as the words are spelled right i have no problem....its like trying to understand a 2nd grader when the words are not spelled right. i dont see anyone on here that capitalizes a word...lol :welcome:

[2ndGenGuy]

I do... but thanks for the welcome. :lol:

hay guys i know why its deseling
my cooling fans are not working. the heat switch for the fans is dead. and my car over heated today and the fans never kicked in.:violin: but shes ok she is still in runnig order.


thanks for the help

mine does that too sometimes, but I know it's because the snake injection system is screwed up. it will be gone shortly though,retired to a box in the loft.
