ps please explain again how i check for worn timing chain.
Popping through the carb can be from the timing being retarded, or a jumped timing chain, or a lean air/fuel mixture.
CCW advances timing, and vise versa.
To begin with (assuming it hasn't jumped time) the points have to be adjusted to 0.016"-0.018". You need to have a strong blue spark at the tip of a grounded spark plug when the engine is cranked. If you don't have a good hot spark, get a new set of points and a condenser.
Use some starting fluid. This eliminates fuel delivery as being a problem. Having a helper makes this easier, but it can be done alone. You do not need a big cloud of starting fluid, just a spritz down the throat w/the choke open.
Some engines are very dependent on the choke to start. The spray also eliminated that from being the problem, but the engine may still want some choke to start cold.
• Timing chain wear
• Install distributor
