Due to the amount of recent posts about hot starting, robB had a good idea that we should list here who has hot starting problems and who doesn't, everyone can join in so we can try and see some sort of pattern.
Please list

Model & year
Air filter Std or other
type & manufacturer of spark plugs
Jet size or carb mods if any
Exhaust system
anything else which may contribute

if we all list in the same manner it will be easier to sort.

mine has to wind for longer than I like but certainly not 10 minutes waiting time

random hot starting problems aswell as lots of other problems with my lemon. [edit/update>>] since new coils, no more problems starting warm, but when hot it either needs, a few quick blips of the starter or open throttle. anything other than hot, straight of the button. [<<edit/update]

basically will not start off the button when hot

I suspect this is just increased friction on the starter gear due to incorrect gasket (combination of cereal packet and mank) on the alternator cover.

ordered a new gasket, will see!

Can we start listing if you have carb heaters? Or if you have already posted edit your post. Youll know carb heaters as there will be a tube that links from the pipe by the genny cover upto the carbs and then out the other side and back into the engine block.

looks like this, see the green bottle type thing? Thats the tube thats routes coolant to the carbs to heat them up.

good point robB

updated mine aren't those carb heater pipes standard tho, or jus some models?
