Re: help engine stalls

check where you have 12v.maybe you fitted the wrong coil and did you replace points and condenser.a cheap multi-meter on the boat is a godsend and keep it on there.

Check for spark first, simply because that is easy. If you have spark, then it is time to check your fuel. But one thing at a time. ;) Check for spark and tell us what you find.
