lack of spark

[bodge00ñ3]

Hi. This may be a weird request
I have a small 2 stroke engine attached to a jet wash.
I have only had this working once.
The spark is very weak and I have now changed the coil and plug. The spark is still weak.
Could this be caused by a weak magnet in the flywheel.???
if so could i improve the magnetic power by placing a electro magnet by the flywheel and hope this would improve it.???
Hope you can help

at hand-crank speeds, the spark can often look weaker than when it finally starts & runs - I'd spend some time looking elsewhere for the problem

Thanks for that . I will investigate further. Perhaps I will see if I can increase the length of the pull cord to get more revs.

first thing i attack on any small engine is the carb. tear it down, blow it out, reassemble. works about 80% of the time.

easy way to work out which way to go?

take carb off. pour a bit of fuel down the intake hole. then try starting it.

if it dont start...its spark or something inside the engine. if it does start...its the carb.
