Number will not firer

<< < (2/2)

Yes

McCabe-Thiele (Ted):
You will know the expression if there is fuel, compression & spark at the right time the cylinder should fire.

Is it a nice strong spark or could it be failing under load?

Oddjob:
I’m betting number 2 carb is flooding and causing the cylinder not too fire as there is just too much petrol in that cylinder. Try taking the plug out of no2, turn off the petrol, leave it for a day or so to allow for any excess petrol in the bore to evaporate and without turning on the petrol refit the plug and see if it starts then.

If it does you know it’s carb related.

Harrier want to be:
Thanks I will give that a try

Harrier want to be:
It turned out the carbs were so out of sync that number 2 wasn't  sucking
